Maciej Suminski 9c4e02379a Added the 'cached' parameter for VIEW_LAYER. The parameter decides if items drawn on the layer should be cached or drawn in immediate mode.
Removed m_useGroups from VIEW, as now groups are enabled per layer.

Maciej Suminski ef865aab68 Grid settings apply to GAL based rendering. 2013-06-24 14:33:02 +02:00
Maciej Suminski fd6ab6003d Bug fixes:
- VBO_CONTAINER::allocate() was returning wrong value in case of error
- framelimiter had wrong formula for computing destined period between frames
- removed _padding field from VBO_VERTEX, as it was not speeding up, but wasting memory

Maciej Suminski 929a849b99 Added a framerate limiter.
Now it does not use all the CPU power while panning even on simple boards.

Maciej Suminski 876bf75d89 Added GAL_TYPE_NONE as an indicator of GAL uninitialized state. 2013-06-18 16:19:30 +02:00
Maciej Suminski 04b4f236be Switching to OpenGL using shaders backend on the fly (changed keyboard shortcuts: different backends are available using Alt+F9..F12). 2013-06-04 16:18:33 +02:00
Maciej Suminski 28511cf4fe Introducing shaders.
Shader's parameters are stored in VBO_ITEM. Changed VBO_ITEM data structure. Added UseShader() function for selecting shader for a given VBO_ITEM.
Added one main vertex & fragment shader program to be used for with all kinds of items (type of shader is selected using attributes that are stored in VBO). Currently available shaders are: at-least-1px-width line, filled circle and stroked circle.
Removed unnecessary param (aDepthOffset) from a few functions (OPENGL_GAL::drawSemiCircle(), OPENGL_GAL::drawLineCap()). Removed function OPENGL_GAL::DrawRoundedSegment(). Changed some asserts to debug info or error log.

Maciej Suminski 806dd7d8ec Items are not recached until GAL is changed (earlier it was done on every rendering backend switch). 2013-05-15 09:17:42 +02:00

Maciej Suminski e8f33ac903 Fixed memleak, removed excessive recaching, still there is a problem with Cairo caching 2013-05-10 16:05:40 +02:00

Tidied up event handlers.

Maciej Suminski bee0d69289 Cleanup 2013-04-16 11:16:27 +02:00
Maciej Suminski 820e6e5e16 Introduced Cairo-based rendering backend using GAL.
Moved switching canvas routines to pcbnew, as they are used only there right now (otherwise libgal would have to be linked to every Kicad application).

Maciej Suminski 0d85444062 Fix for compatibility with wxWidgets 2.8 & 2.9 at the same time. 2013-04-10 10:09:23 +02:00
Maciej Suminski e262b32198 Introduction of Graphics Abstraction Layer based rendering for pcbnew.
New classes:
    - VIEW - represents view that is seen by user, takes care of layer ordering & visibility and how it is displayed (which location, how much zoomed, etc.)
    - VIEW_ITEM - Base class for every item that can be displayed on VIEW (the biggest change is that now it may be necessary to override ViewBBox & ViewGetLayers method for derived classes).
    - EDA_DRAW_PANEL_GAL - Inherits after EDA_DRAW_PANEL, displays VIEW output, right now it is not editable (in opposite to usual EDA_DRAW_PANEL).
    - GAL/OPENGL_GAL/CAIRO_GAL - Base Graphics Abstraction Layer class + two different flavours (Cairo is not fully supported yet), that offers methods to draw primitives using different libraries.
    - WX_VIEW_CONTROLS - Controller for VIEW, handles user events, allows zooming, panning, etc.
    - PAINTER/PCB_PAINTER - Classes that uses GAL interface to draw items (as you may have already guessed - PCB_PAINTER is a class for drawing PCB specific object, PAINTER is an abstract class). Its methods are invoked by VIEW, when an item has to be drawn. To display a new type of item - you need to implement draw(ITEM_TYPE*) method that draws it using GAL methods.
    - STROKE_FONT - Implements stroke font drawing using GAL methods.
                          
Most important changes to Kicad original code:
    * EDA_ITEM now inherits from VIEW_ITEM, which is a base class for all drawable objects.
    * EDA_DRAW_FRAME contains both usual EDA_DRAW_PANEL and new EDA_DRAW_PANEL_GAL, that can be switched anytime.
    * There are some new layers for displaying multilayer pads, vias & pads holes (these are not shown yet on the right sidebar in pcbnew)
    * Display order of layers is different than in previous versions (if you are curious - you may check m_galLayerOrder@pcbnew/basepcbframe.cpp). Preserving usual order would result in not very natural display, such as showing silkscreen texts on the bottom.
    * Introduced new hotkey (Alt+F12) and new menu option (View->Switch canvas) for switching canvas during runtime.
    * Some of classes (mostly derived from BOARD_ITEM) now includes ViewBBox & ViewGetLayers methods.
    * Removed tools/class_painter.h, as now it is extended and included in source code.
                         
Build changes:
    * GAL-based rendering option is turned on by a new compilation CMake option KICAD_GAL.
    * When compiling with CMake option KICAD_GAL=ON, GLEW and Cairo libraries are required.
    * GAL-related code is compiled into a static library (common/libgal).
    * Build with KICAD_GAL=OFF should not need any new libraries and should come out as a standard version of Kicad
                            
Currently most of items in pcbnew can be displayed using OpenGL (to be done are DIMENSIONS and MARKERS).
