Hi Alex, Perhaps you're right, but I think the circle texture is drawn by call to drawSprite2d(). Eg. texCircle.bind(); sPainter.drawSprite2d()
(sorry I don't have the code in front of me.) The drawCircle routine sets up an array of 180 vertices (Vec3D) and then calls glDrawArray(), so I think the geometry comes from the vector passed as argument, not the texture. Maybe I need to set up some normals or something? I don't know much about GL programming but I'm keen to learn. When I get home tonight I'll look in the code for other places drawCircle is used, to try to copy it.
