add overloads for NODE::Add( ... ) taking pointers to specific item types (retain old private add-Functions, they will come in handy later)
LINE overloads now take by reference, to document their special treatment.
updated code throughout affected by these changes
The DRC also runs per-segment tests, not just segment-segment, so the last
segment needs to be tested as well, with an empty list of segments to test
against.
* When Pcbnew is launched in the stand alone mode with no board file command
line option, the project path is set to the current working directory. The
user may not have write access to the current working directory which would
cause the auto save to generate an error. If the user does not have write
access to the current working directory, set the path to a platform specific
temporary path that the user has write permission.
* When Pcbnew is launched in the stand alone mode with no board file command
line option, the default BOARD object has no file name. Set the file name
to "noname.kicad_pcb" to fix incorrect auto save file name and set the path
to the user's platform specific document folder.
* Delete orphaned auto save files when closing without saving due to broken
auto save file generation logic which prepended the file name with "$" rather
than "_autosave-".
* Fixes: lp:1596382
* Split and rewrite the preview window and canvas.
* Create a new class for handling the board information.
* Adds new render targets: openGL, legacy, and ray tracing.
* Render targets take full advantage of the new 3D plugins system and 3D cache
for a fast 3D model loading.
* Faster board loading.
* New OpenGL render is faster than the old one.
* New ray tracing render target with a post processing shader.
* Use of new 3D plugins (WRL, X3D, STEP and IGES) and 3D model caching.
* Preview of 3D model while browsing the file name.
* 3D preview of the footprint while adding / align 3D shapes.
* Render of 3D models according to attributes: Normal, Normal+Insert, Virtual.
* Pivot rotation centered in one point over the PCB board.
* Shortcuts keys improved for XYZ orientation..
* Animated camera.
* Switched hashtables.h over to std::undordered_map from boost version.
* Added new macros DECL_VEC_FOR_SWIG() and DECL_MAP_FOR_SWIG() in macros.h.
These along with future DECL_HASH_FOR_SWIG() unify the declaration to swig
and C++ so that the resultant type name is common in both languages, and
the types AGREE.
* Fixed swigging of NETINFO_ITEM and NETINFO_LIST via magic.
* Newly exposed (python wrapped) are: D_PADS, TRACKS (was TRACK_PTRS),
NETNAME_MAP, NETCODE_MAP, wxString (without constructor purposely, read
comment in wx.i), MARKERS, ZONE_CONTAINERS, NETCLASSPTR, KICAD_T types.
* std::vector<SOMETHING*> tends to end up named SOMETHINGS in C++ and python.
Having the name consistent between like types is helpful, and between
languages. std::map<> ends up as SOMETHING_MAP.
* NETINFO_LIST::m_netNames and NETINFO_LIST::m_netCodes are now std::map
instead of hashtables, because swig does not yet support std::unordered_map.
* You can now get to any netclass or net info. NETNAMES_MAP and NETCODES_MAP
are traversable basically the same as a python dictionary using a python
string (not wsString) as the key! The wxString typemap converts python
string to wxString before the lookup happens. Iteration also works.
* Factor out PROPERTIES object from the PCB plugin code and move it into
common so it can be used by both the Pcbnew and Eeschema plugins.
* Add schematic I/O plugin manager for loading and saving schematic and
component library files.
* Add initial attempt at a parser for current schematic file format. This
parser will be infinitely more strict than the current parser which is very
forgiving in what it parses.
* Make minor changes to the base bitmap class to support the new parser.
* Add find root sheet support to sheet object to allow fetching the root
sheet from any sheet in the stack.
It is especially true in some Window Managers like KDE, but can be true in any WM, when initializations are made by TransferDataToWindow() method, called by the default wxInitDialogEvent handler.
This revised nginx.conf holds the cache for one week, truly. For some reason there are
two tuning knobs required to make one adjustment (cache duration). Without this fix the
cache was only held for 10 minutes. The most important change is the "inactive=1w" which
as I implied, is the *second* reference to one week. Sorry for this oversight.
Nginx can be run on something as simple as a raspberry PI. I run it on a network file
server attached to my desktop via copper ethernet. By caching the footprint libraries
from github, I can load all github libraries in about 2.5 seconds, making github the
fastest plugin of any kind.
This feature was not reliably available: neither pl_editor nor GAL supported
it. It has been replaced over the past few commits with a new zoom-to-selection
tool available in all applications and modes.
While defining functions in another namespace is technically allowed as
long as the definition can be matched to a declaration, this can lead to
ambiguous resolutions, such as here (GAL vs KIGFX).
This feature cannot work reliably for reasons explained in lp:1463505. Remove
the option on OS X builds and force cursor to the small one.

Coverity: CID 147344 Unchecked dynamic_cast
If a file that parses validly in Parse() but does not return a BOARD is loaded,
no exception will be thrown but the dynamic_cast will return NULL. This NULL
is tested by wxASSERT(), which does not actually halt anything (especially in
release builds), and then we proceed to board->SetFileName().
This can be demonstrated quickly by renaming a .kicad_mod to .kicad_pcb and
trying to load it. pcbnew will crash.
Currently, kicad_pcb files have a (version ...) tag, but it is ignored. This
commit does the following:
1. Parse the version. If it's later than the last supported version, present an
alternative error message suggesting an upgrade if the file does not load
correctly. The version will be interpreted as an integer YYYYMMDD to suggest
a KiCad release date.
2. Accept a (version ...) tag also in kicad_mod files, but do not write them
yet. If no version tag is present in these files, assume the version to be that
of the current format version at the time of this commit.
This is meant to be merged to the 4.x stable series, and preps for KiCad 5
which will start emitting version tags also in footprints - users with what
will then be 'old stable' will not get a parse error when we introduce this for
footprints, and we can safely increment the format version later.
It should help if (or when) the internal angle unit used in kicad will be changed from 0.1 degree (a relic of code written for PCs without fpu) to degree ( a more natural unit).
* Always hide footprint text when the layer that the text resides is disabled
in the layer manager. There is no longer a difference between the value and
reference text compared to other field text.
* The usual smattering of coding policy fixes and general code cleaning.
* Paths defined via pcbnew->Preferences->Configure Paths are now included in
the 3D file browser's drop-down list except for KICAD_PTEMPLATES, KIGITHUB,
KISYSMOD, any paths resembling a URL, and any non-existent paths. When an
absolute path is shortened using one of these path aliases, let's say
'KISYS3DMOD' then the name appears in the pcb file as "${KISYS3DMOD}/blah.wrl".
If a user defines and actual environment variable with the same name, then
that user defined variable will have precedence over the internally defined
variable.
* Paths relative to the current project directory are no longer represented
as "some/path/to/file.wrl". For compatibility with previous KiCad versions
it shall always be stored as ${KIPRJMOD}/some/path/to/file.wrl.
* Various restrictions on alias path values have been removed since the
imposed restrictions could result in corrupted user data as aliases are
silently dropped.
* Overall the patch should improve back-compatibility by providing a ${ENV_VAR}
mechanism for supporting different model root directories and ensuring that
paths relative to KIPRJMOD are expressed in a way that is compatible with
earlier KiCad versions. This allows users more flexibility and the ability
to work in a way that ensures 3D model files can be correctly resolved in
earlier versions of KiCad. Users who do not care about back-compatibility
may prefer to use the newer alias system.
Fixa also a corner case which crashes Pcbnew: if the dialog is opened, and the board was changed (reloaded, cleared), pcbnew crashed because many pointers stored in dialog become invalid. Now the dialog is just closed.
- When the Kicad manager is iconized, all other child frames are iconized (normal wxWidgets behavior)
- For viewer frames in modal mode, there is a more annoying issue: they have the wxFLOAT_ON_PARENT frame style on unix, and wxSTAY_ON_TOP on Windows.
wxFLOAT_ON_PARENT frame style is incorrect (although on most WM it works) because the parent frame (Kicad manager Frame) is not the caller. It is usually a main editor frame.
It does not work on Windows (wx STAY_ON_TOP is used).
* Now each editor frame has a null parent.
Therefore iconizing the Kicad manager frame does not iconize other frames.
* Viewer frames have null parent in normal mode and the caller parent in modal mode (therefore wxFLOAT_ON_PARENT frame style is always and correctly used)
* References to opened/closed main frames are no more managed by the (complicated) kicad code. Instead of, a non critical and more easy to understand code just uses FindWindowByName to know if a main window exists or not.
These changes do not fix all issues about Kicad frames brought to the foreground or the background, but it fixes a few issues, and AFAIK do not add other issues.
The attached patch makes the following changes to import DXF:
1. correctly implements scaling based on DXF $INSUNITS -
at least where INSUNITS is sensible. I ignore units like miles,
gigameters, AU, lightyear, parsec ...
2. correctly implements LWPolylines, adding an ARC segment
rather than a line segment when bulge != 0. A number of users
have been complaining about getting the wrong board shape
(chamfered corners rather than rounded corners) on DXF Import,
now they shouldn't complain.
Following rev 6627 (git 2777182), if a non-duplicatable item was the object of
a Duplicate action, the original item would be picked up, potentially
misleading the user into thinking something was actually duplicated.
Do not assert that the item to be duplicated can be duplicated, just don't
duplicate it. The user can trigger a Duplicate on items that aren't
duplicatable, like field texts - he'll figure out that they can't be duplicated
when they aren't, no need to deliver a scary warning and risk an abort.

TODO: Don't pick up the duplicated selection if none of the items in it were
actually duplicated, it's misleading.
* On MinGW64 and possibly other 64-bit platforms, time_t is defined as a long
long unsigned integer but all of the scanf and printf format specifiers used
to save and load the schematic files are %lX which is a long unsigned integer
which causes compile warnings. Add casts and temporary variables to eliminate
the compile type warnings.
I tried to merge some constants used both in legacy mode and gal mode (which were, before this patch, separate constants).
There is still a serious work to avoid different calculation code for the same text in draw and plot functions.
Work in progress to merge these calculation functions.
* No initial copied object changed (this was a serious bug to modify these objects. Previous version modified references and other texts using a very stupid algorithm).
It also fixes bug 1549231
* only new pads are numbered (therefore renumbering is used only in footprint editor)
* remove not working and useless feature in circular array: now only use number for pads (others options using alphabetical letters are removed: did not work corectly, and were useless)
* a more clear option is used to choose if the pads are numbered from a choosen value, or from the first avaible value
* Adding a warning messsage if a parameter is incorrect.
* Move add_directory()s in main CMakeList.txt after all find_package()
macros are run so all flags in the main CMakeList.txt are propagated
to the sub-folder CMakeList.txt files.
* Remove commented out include of config.h
* Make the link maps only build on linux as -${TO_LINKER},-cref
-${TO_LINKER},-Map=blah just gives warnings on osx w/ clang
* Make the link maps only build with flag -DKICAD_MAKE_LINK_MAPS is
defined during CMake configuration as they are highly specific.
* Moved the code for setting link maps into the main CMakeList.txt
file to avoid duplication.
* Removed -D__ASSERTMACRO__ from osx as its no longer needed
* Removed a couple of other OSX only things that wouldn't work anyway
* Moved set (BU_CHMOD_BUNDLE_ITEMS) to the main CMakeList.txt as
otherwise it would only work for the KiCad build not the other
applications
* Made KICAD_SCRIPTING_MODULES enable KICAD_SCRIPTING as currently if
you have modules enabled without the scripting base it will on build.
This could be changed to a fatal error saying you need to also enable
scripting but it seems unnecessary.
* Removed duplication of pcbnew.py install code under modules and
scripting since you can't have modules without scripting now
* File import: use case insensitive comparison to choose import plugin, from the file extension (It is not always in lower cases, especially on Windows.)
* onleftclick.cpp: fis a minor issue, which happens after switching form GAL to Legacy canvas: sometimes a board item is left selected from GAL, and creates false warning message in legacy.
* Dialog copper zones: Always enable thermal shape settings, because even with no thermal, some pads can use thermal option in local pad settings.
* GAL mode: shows page limits in gray color, like in legacy mode, and according to comments in sources.
* Fix a StrPrintf() %s count mismatch bug
* Better comments
* Use std::string::data() instead of a ref to the first char to get the str::string buffer (should not change anything with GNU lib)
* The resource setting for bitmap2component is too late in the CMakeLists.txt,
and is being ignored. Bitmap2component does not have an icon resource on
Windows. Moving the entire section resolves the issue.
* The other programs only have the mingw special case listed, not the generic
declaration for the resource file so added them.
The standard library requires iterators passed to functions that modify the
container to be mutable iterators, but GCC's implementation accepts
const_iterator in some places where these are only used to mark a place,
but the actual modification happens through a different parameter.
As this breaks implementations that use the passed iterator to modify the
container (e.g. because they use a different data organization), this is
not portable; because we already have a non-const reference to the
container anyway, this is trivially fixed as well.
In the C++ standard, this function is only defined for floating point
types, and integers cannot be implicitly converted. Using explicit
conversions avoids a GCC specific extension to the standard library.
This was apparently left in from debugging earlier, and should no longer be
needed. Since it uses a GCC extension, it makes compilation on others fail.
In the autorouter code, the value 0x80 is assigned to MATRIX_CELL, which is
an overflow for a signed 8-bit type. As this type is used as a bit mask,
there is no point in having a sign bit anyway.
The C++ preprocessor is actually not required to process "true" and "false"
correctly. This works in C if <stdbool.h> is included, because these are
then macros themselves, and resolved correctly, but C++ requires them to be
keywords, so no such macros exist, and the preprocessor can treat both as
undefined/zero.
Mostly cosmetic change, although there are compilers that choke on this.
The C++ standard specifies that classes contain themselves as members,
probably so they shadow any other definition of the same name for their own
member functions, but there is really no reason why the class name should
be duplicated here.
* Prevent libcurl from inadvertently being initialized twice.
* Dynamically load libcurl only when required.
* Reduce the number of worker threads when loading footprint libraries to
prevent issues with the GitHub plugin.
This simplifies the pad DRC significantly and fixes a bug when two pads
are close to each other in a right angle, when the edge distances are
below the clearance, but the corner distance is actually above the
clearance:

<Chris> Pad DRC has handling for trapezoid pads and handling for square
pads. This patch looks relatively low-risk to me, as square is a subset
of trapezoid and the handling for trapezoid pads is not specific to that
pad type.
* Remove download and build Boost from source and all CMake boost source build
dependencies.
* Make FindCairo.cmake use pkg-config when it's available not just all
platforms except windows.
* Add version checking to FindCairo.cmake.
* Change find GML version to 0.9.5.1 which is the current version in Ubuntu
14.04 LTS.
* Update required Cairo version to 1.12.1.
1. Fixed an assumption somebody originally made in the plugin that std::string had contiguous storage. This is not specced behavior pre C++11 so we gamble by calling .reserve() which should give a far better guarantee.
2. Added copy to clipboard information for curl
3. Removed some openssl references in compiling.md
4. Renamed struct vars to be uppercase to match "public var" code style policy
* fix minor coding style issues.
* remove unused member in modview_frame.
* use different frame names in ctor of modview_frame and viewlib_frame depending on the fact they are built modal or not modal (allowing identifications when calling wxFindWindowByName)
* change questionnable code in class_libentry.cpp.
* remove unused code in class_treeproject_item.cpp
Including the inline of the Output directory and its text field/browse button.
Moving the plot format to the left of the plot options as the plot options depend on the plot format.
In polygon calculations (combining polygons, fracture) the mode of calculation (fast or strictly simple polygon option) as no more a default value, because choosing the best mode is better to optimize the calculation time.
1. incorrect orientation of components on the bottom side of the board
when the #D model rotation is non-zero
2. failure to export when some components have no model set
Pcbnew: auxiliary axis shape: use the same look as GAL, to be consistent with GAL.
Minor change in dialog_env_var_config (use the wxStdDialogButtonSize for usual OK, Cancel and help buttons)
* Fix segfault caused by invalidation of the end item by
PNS_LINE_PLACER::UpdateSizes().
* GAL zone drawing tool updates the ratsnest after zone drawing is complete.
* Fixed performance issue in zones processing using strict simplification
only for the final filled area.
* Replace the term module with footprint.
* Use default dialog size to allow sizers to determine the size of the dialog.
* Fix a few alignment and spacing issues.
* Fix some minor grammatical issues.
* Use front and back for board side instead of top and bottom to be consistent
with layer naming scheme.
2. Whole bunch of pointless casts removed
3. Unused variables removed
4. Fix bug caused by JP on April 25, 2015 where strings were adjusted for translation and the hotkeys section table accidentally swapped the footprint editor title with tag, resulting in "footprint editor" being exported instead of "[footprinteditor]"
No functional changes besides #4, technically it'll "break" imports hotkeys files but April 25 broke imports as well.
* Removed outdated package maker information, the pmdoc is generated and does
not belong in the KiCad tree, it is also highly specific as seen due to the
references to /Users/marco. This is not used in normal builds nor in the
packaging for KiCad OSX nightly builds.
* Updated identifiers in package marker docs to remove references to sourceforge
and to follow other identifiers.
gen_gerber_and_drill_files_board.py:
* fix to make it compatible with rev 6280.
* allow this script to create files in the current plot folder defined from the board forder, no more only in current working directory.
reasons:
* This option is called "bad practice" in gerber files format specifications and is even forbidden in gerber drill files.
* Generates problems with some board makers because these holes are not identified in a single NC file.
* No one was able to explain us how to identified them in a single NC file.
* Recent change in drill file generation is not compatible with merged holes (minor reason)
Drill report: serious enhancements.
Plot files names for copper layers: build from the user layer name, like in bzr 4022 stable version. no change for other layers.
Pcbnew: Plot files: for copper layers, create suffix from user copper layer names instead of default copper layer names, like in last stable Kicad version (bzr 4022), to build the plot files filenames.
Better test of illegal chars in plot filename, both in plot dialog and functions aclled by Python scripts.
Fix a Plotcontroller issue to make SetUseGerberExtensions() work as expected from Python scripts ( from Henner Zeller'patch with a fix to be sure it works properly from a Python script)
Note also using Protel Gerber Extensions is now a bad practice, because the official Gerber extension is .gbr since X2 Gerber version. But some users still use them)
* The board ratsnest visibility state was being saved in both the board file
and the Pcbnew configuration files causing visibility state issues. Use the
board file to save the board ratsnest visibility state.
* Remove all of the board ratsnest save visibility state to configuration file
code.
* Add code to set the board modified property when layer visibility states
change to give the user a chance to save the state in the board file.
* Some minor code cleaning and coding policy fixes.
* Recognize values with units in more recent gEDA footprint files and scale accordingly.
* Join both parseInt() implementations. This should reduce rounding errors as well as
code duplication.
* Make the about dialog help string consistent across all menus.
* Improve print preview window and print initialization error messages.
* The usual smattering of coding policy fixes.
* Add skip event to notebook page changed event handler. Apparently OSX
updates the selected notebook page in this event instead of the page
changing event used on Window and Linux.
* Improve duplicate net class name error message.
* Use default dialog size to allow sizers to do their job.
* General layout and sizer improvements.
* Remove HTML message window which could not be used when error dialog was displayed.
* Use wxStdDialogButtonSizer for the OK and Cancel buttons.
* Check for design rule validity in TransferDataFromWindow() to prevent dialog from being
closed and all new design rules being lost when an error is detected. This gives the user a
chance to fix any design rules errors before dismissing the dialog.
* Add missing test for extra via drill diameter violations.
* Remove unnecessary OK and Cancel butten clicked event handlers.
* Coding policy fixes in the scripting initialization code missed in my previous commit.
* Remove redundant checks for valid Python library paths in kicadplugins.i.
* Actually install the contents of the pcbnew/scripting/plugins directory on
Windows and Linux
* Move the test for existence of a directory before adding it to the Python
system library paths when loading the Python plugins.
* Rename Eda_FileSelector to EDA_FILE_SELECTOR.
* Add optional pointer to wxString to save the most recently used path to EDA_FILE_SELECTOR.
* Rename Eda_DirectorySelector to EDA_PATH_SELECTOR.
* Replace wxGetCwd() with wxStandardPaths::GetDocumentsDir(). This fixes the windows issue
where wxGetCwd() returns the path where the executable files are located.
* Add code to handle most recently used path to EDA_BASE_FRAME.
* Fix string formatting error in kicad/files-io.cpp.
* Remove setting and restoring current working directory when launching GerbView. Setting the CWD
has no effect on the launched executable which starts with it's own CWD.
* Allow project path to be passed to GerbView when launched from KiCad.
* Note: this is a work in progress. Do not expect every path and/or file selection dialog to properly
update the most recently used path. The correct solution to this problem requires a much more
well though out solution which will not happen until after the next stable release.
* UI capitalization policy fixes.
* Set OK button as the default.
* Use default dialog size to allow sizers to do their job.
* Minor grammar and abbreviation string fixes.
* Make OK button the default in the copper zones properties dialog.
* Change the set global text edit properties menu entry so that is describes
what the dialog actually does.
* Make the clean up tracks and vias menu entry description more accurate.
* Track the last used path for the current session.
* Set focus back to OK button after wxFilePickerCtrl button is pressed to change file path
and/or file name so next return key press fires OK event.
* Use default dialog size to let the sizers set initial dialog size.
* Add spacer to improve layout when resizing dialog.
* Use colons for consistency with other dialogs.
* Use default size to allow sizers to determine dialog size.
* Use "segment" rather than abbreviation "segm".
* Use width and height to describe text instead of X and Y.
* Add spacer to improve layout when resizing dialog.
* Use colons consistently in labels.
* Use default dialog size to allow sizers to size dialog.
* Fix control alignment and spacing consistency.
* Add spacer to improve layout when resizing dialog.
* Make control spacing and alignment consistent.
* Use default dialog size and to allow the sizers to do thier job.
* Add colons to per item labels for consistency.
* Fix error message box title capitalization per UI policy.
* Remove hard coded dialog size and let the sizers do their job.
* Minor UI policy text fixes.
* Minor text changes to improve readability.
* Minor tool tip changes to improve readability.
* Split graphic circle objects into two 180 degree arcs to prevent the
VRML_LAYER::AddCircle() function from obscuring objects in the hole
(cut out) area of the circle.
Replace %zu by %d in wxString::Format (%zu format not always known by wxString::Format on Windows, depending on the way wxWidgets was built ) in a few messages
* Mainly the wxDialog that was opened when the wizard is created is now no more created by the wizard frame CTOR. On some W.M. it created a serious issue related to the way Event Loops are managed. Now the user has to call it by the toolbar tool.
* 2 settings not saved in config are now saved.
* a few other minor enhancements
* better icon in footprint wizard frame
Remove a few #define relative to the wxWidgets 2.8 version, no more supported.
footprint wizard frame: now shows messages from footprints python scripts. Especially usefull when a parameter is incorrect. Fix also an other issue (IO exception error) with some python scripts when they are usin a print command to output messages (now they use the new message window.

* Catch all unhandled exceptions derived from std::exception() class in
KICAD_PLUGIN::get_remote_zip() to prevent KiCad from crashing when
exceptions are thrown from the C++ standard library.
* Make boost::system::system_error() catch const and and improve comments
about avhttp library usage in KICAD_PLUGIN::get_remote_zip(). Thanks to
Dick Hollenbeck for these improvements.
PAD_SHAPE_T and PAD_ATTR_T still have a double definition (new names and old names) to be sure python scripts are nor broken by the change.
PAD_DRILL_SHAPE_T does not have a double definition, because it is unlikely oblong holes are used in python scripts.
Double definitions will be removed in the (next) future.
Fix an issue when a .kicad_pcb file contains an incorrect fpid ( containing a '/ ' in footprint section ) . After saving the board the file was no more readable, due to a broken fpid saved in file
(can happens in old .kicad_pcb files, coming from the bzr 4022 stable version, and/or in files converted from an other EDA tool like altium)
Fix 2 very minor coverity warnings.
* The exchange dialog can be now called from the footprint popup menu.
* It can be (as before) called from the footprint properties menu, but in this case, the footprint properties menu is closed before calling the exchange menu.
* Changes in exchange dialog to avoid truncation of long FPIDs
* Changes in exchange dialog to make some texts translatable (Previously, the same English sentence was used in very different contexts)
- PNS_ITEMSET now keeps ownership info (does not rely on PNS_ITEM::Owner(), avoiding the risk of dangling pointers)
- fixed vias losing connected traces when dragging in mark obstacles mode
- fixed rare segfault when board item returned null netclass
* Cleanup namespace in enum ZoneConnection in pcbnew/zones.h to self-explained names unification: PAD_ZONE_CONN_INHERITED, PAD_ZONE_CONN_NONE,PAD_ZONE_CONN_THERMAL,PAD_ZONE_CONN_FULL, PAD_ZONE_CONN_THT_THERMAL
* Adds a "Grid Reference Point" to the VRML export; this allows a user to specify the (X,Y) coordinate which will be the origin point on the output
* Adds a "Grid Reference Point" to the IDF export; this is similar in purpose to the corresponding VRML export feature.
