Detailed Description

Convert VRML to vrmlshape class.

The VRML is restricted to points and normals as triangles.

Example

  vrmlshapeparse p;
  p.readfile("p3.wrl");

  vector<vrmlshape> s;
  vrmlconvert()(s,p);

Note that no optimization occures. If a software package exports crap VRML - for example every triangle is an indexed face set this converter stores each triangle as a vrmlshape. I suggest using something to compile the static geometry (eg OpenGL display lists) after it has been converted.
