I tried the python end of things, and found this unusually pleasant effect with the Quartic example! If I got inside the Quartic shape, all sorts of cool things happened when I messed with line# 101 of the Quartic_Builder.py file! I changed: p = -0.375*c12 + c2; the -0.375 to other values like, -0.5, etc. which drew this picture. The normals of the raytracer seemed to flip over wildly! (Those extra lines are the reflections of the simple "Glass Building" material, as a particularly cool value of -0.5.) Positive values seemed to invert the closed default Quartic shape into the hyper-bowl of itself, as it were. I thought that an interesting and short featurette of this room and the way it changed, especially when sweeping the value gradually through its zero reversal, was warranted. But the resource utilization reminded me of skynet! With each pass, the CPU labored at a geometric rate!!! Alas, this lowly, blocky facsimile of an image, a flounder stuck in a receding tide, was all that could be rendered (drunken troubleshooting aside.) Cheers!!
