* This program takes an IDF base name, loads the board outline
|
|
* and component outine files, and creates a single VRML file.
|
|
* The VRML file can be used to visually verify the IDF files
|
|
* before sending them to a mechanical designer. The output scale
|
|
* is 10:1; this scale was chosen because VRML was originally
|
|
* intended to describe large virtual worlds and rounding errors
|
|
* would be more likely if we used a 1:1 scale.
