I can't speak for the others who are excited about the possibility of
creating a BrickML, but to me it kind of seems like a logical successor to
the LDraw file format, given that it could handle meta-data elegantly and do
everything that the LDraw file format can do, plus more.
The practical capabilities that a BrickML would add include:
- The ability to convert a part to both LDraw's .ldr file format and to
POV-Ray's .inc file format -- from the same master part specification.
BrickML could include, for example, a cylinder primative which could be
output at a POV-Ray cylinder object or as a set of LDraw triangles
approximating a cylinder. It could include a color specifier which would
output as the appropriate RGB color for POV-Ray or as the appropriate LDraw
color for LDraw. It could be a really nice way to unite LDraw, POV-Ray, and
other 3D systems.
- Ease of including meta-data and outputting it as LDraw or POV-Ray comments.
- Possibly easier to validate syntax than .ldr for new tools. (This is
marginal, though.)
The big win would be native suport for things like cylinders, spheres,
cones, meshes, and textures. And it could do CSG. A conversion to .ldr or
.pov would be accomplished by using whatever primatives were available, so
that the result would be of the highest quality.
