Creating a colored cube with each face colored differently?

sachuraju
Hi,

In developing the Rubik's cube, I'm now in the final stage where I need to create a cube with all 6 faces of different colors.

When I look at how one assigns a color to a cube, we create a Material object, and pass it to the TCube. The TCube passes it to its super classes, and finally we hit TMesh, where the material object is put into the MaterialList (at 1).

Then at render time, I see that the method renderPrimitve: ogl alpha: alphaPass is called to render the object, in which the materialList is made use of. Not being a graphics guy myself, I'm unable to figure out what is happening in this function, and so it would be great if someone can put into words what is happening in that method.

This will help me change the method so that I can perhaps use it to render a cube with all faces colored differently.

Thanks.

The TCube may use the same material for all 6 sides if I recall. You may need to create your own object, probably by using 6 TRectangles properly oriented. Each rectangle can have its own material that way. Another possibility is create the cube you want in a 3D editor, export to collada and load it into your scene. Then just make 26 copies (don't need one in the center).

And by the looks of it, I think that doing the latter seems simpler?

Yes. If you have the ability model it, it should be quite a bit easier.
