Feature request details

cylinder() already has parameters bottomCap and topCap. But there's no way to just draw the cap(s). I'm suggesting adding another optional parameter sideWalls default to true, but when false doesn't draw the side walls of the cylinder.

Would placing two circle()s already cover this case?

[blackboxlogic]

I didn't see a way to use circle() in 3D space, with webGL. I want to change its xyz, rotate it in 3D, apply lighting etc

[davepagurek]

For all 3D shapes, you can call translate(...) or rotate(...) before your call to circle() to change the position and orientation of whatever you're drawing. I believe that should also include normals, so if you enable lighting and materials before drawing the circles, they should apply.

[blackboxlogic]

I assumed, read, or misunderstood that 2-D shapes couldn't be used in 3d space. I've verified that circle() does exactly what I want. Thank you.

ok nice! yeah, that's something that maybe could be made clearer in the docs or tutorials too.
