A quick question, if you will. I'd like to use a 3-layer 3d texture (the textures are highly pixelated to begin with) to simply represent either grooves / holes in a surface, or bumps/protrusions. Getting 3d textures to work will probably be some work (I do already 'correctly' texture 2d quads) so mainly I just want to know, for anyone who has made use of them or knows their effect, whether or not it will be worth the trouble? Can I get a reasonably blocky effect from a 3d texture, that will not overly complicate lighting?
And I guess if so, (I'd imagine you can turn to GL_NEAREST for depth(R) blending as well as T and S blending) does the texture loader work well with 3d textures? I've noticed most examples show making a special 4-dimensional buffer (color,x,y,depth) and filling it with the image data. Does slick-util help with this or will I need create the buffer to load the PNG's into the buffer manually?
So many questions. Why can't I hold all the questions
