Does BlitzMax use 3D meshes? Or 2D meshes, for that matter?
Define: 3D meshes and 2D meshes. Does it, for example, render triangles, or only images?
Triangles. I don't think you can render "only images". Is there an AddVertex command, for example?
Not directly, no. Does BlitzMax render images/triangles at specific pixels, or at arbitrary coordinates like with Blitz3D's Graphics3D?
Specific pixels.
