About this 3D model

You know in those Japanese anime movies where the character gets question marks above their head, and their cheeks go red when they're embarrassed? I had a smack your head moment as I realized that OpenScad has a polyhedron object!This thing is a very slight modification to the test_bezier.scad file. It includes a DisplayBezSurface(mesh) routine which will actually draw the surface using polyhedron to place the triangle patches.That makes the final stage a whole lot easier. Now, instead of trying to use the polygon, and project it into position, I can simply use the polyhedron, and construct an appropriately shaped polyhedron to get the patches at the desired thickness!So, once I do that, I'll go to version 0.9, and 1.0 will be when it's all nicely packaged up into a couple of clean library files.One more step, one more pretty picture.With this technique, now any parametric surface is possible, including b-spline and the like.
