| | | How the heck do I make good teardrop shapes in POV-Ray? I've tried with all manner of paired half-spheres, but I can't get the right "pinchiness" on the narrow end. I've also tried experimenting with splines and SOR formations, but I can't generate (...) (22 years ago, 13-Nov-02, to lugnet.cad.ray)

| | | | | | (...) A good suggestion! Maybe I can play around with a half-sphere, an open-ended cone, and a smaller half-sphere at the narrow end, but I'd kind of like to retain the roundness rather than the straight surface of the cone. I'll have to (...) (22 years ago, 13-Nov-02, to lugnet.cad.ray)

The first and last points are the endpoints of the segment, and the (...) (22 years ago, 14-Nov-02, to lugnet.cad.ray)
