(...) Defining the material would be one side of the issue. We (ie, the LSC) could adopt/adapt the LDLite COLOR statement to handle materials. My question is really on the technical side: I'm somewhat aware of the technique of texture-mapping, but I (...) (22 years ago, 1-May-03, to lugnet.cad)

(...) Create a 0 MATERIAL extension instead, where you can define the properties of the surface (smooth, bump, rubber, etc.) and keep the color selection using the standard LDraw way so we don't break compatibility. (...) This is a case by case (...) (22 years ago, 1-May-03, to lugnet.cad)

(...) I like this. It would allow you to define a bunch of materials up front and then apply them to some of the surfaces. Could we use this for printed textures as well, or would that be better with a different meta-command? How would you apply the (...) (22 years ago, 2-May-03, to lugnet.cad)

(...) I was thinking we would have a pre-defined set of materials, so we don't need to define them. (...) That's what I had in mind. (...) You need texture coordinates to be able to apply textures but you don't need them for smooth, rubber and (...) (22 years ago, 2-May-03, to lugnet.cad)

(...) I appreciate that. But the only software I've seen use texture mapping has been based on raytracing. Well, actually I don't know how most gaming engines work. BUT, I still want to know -- is there a texture-mapping algorithm that mere mortals (...) (22 years ago, 10-May-03, to lugnet.cad)

(...) Yes, I think it would be good to not encode the materials in the rendering programs. There are always going to be new materials, just like LEGO keeps coming up with new colors. (...) That would work for some things, like bumpy surfaces on (...) (22 years ago, 10-May-03, to lugnet.cad)
