  == What software could you recommend for animated 3D math sketches? ==  Sir, you are awesome, thanks a lot for your clean and deeply precise animation! Could you recommend some tools for creating animated math sketches like yours? I realize that it depends.  * 3dsMax, Maya, Blender seem to be overhead, * CLUCalc is nice, but raster, * to write custom scripts for SVG/pgf/TikZ is to reinvent a wheel.
