(...) Looks good. Should we create a new primitive with the next dimensions:? 2 24 0 0 1 0 1 1 2 24 1 0 -1 0 1 -1 2 24 0 0 1 1 0 -1 2 24 0 1 1 0 1 -1 and a POV-quadric version in the coming L3PPARTS. As the outer twisted surface of the parts with (...) (20 years ago, 25-Apr-05, to lugnet.cad.dat.parts)

(...) Nice, I like the idea of the quadric primitive, but we want to add some curvature to the LDRAW version, right? I fiddled a bit with the part a few days ago, starting with the two triangles outlined by your primitive. I didn't exactly finish, (...) (20 years ago, 25-Apr-05, to lugnet.cad.dat.parts)

(...) The following are the appropriate conditionals for Don's surface. Playing with it you can have angles where the conditionals seem to go too far, but it's certainly much better than the current ones. (Note that the last 4 conditionals are only (...)

(...) Hey, thanks testing it out. You're right about the conditionals zig-zagging a bit. I still have the feeling that if the surface were pinned down to the concave green line those zig-zags would go away. But I couldn't decide whether to divvy it (...)

(...) Good idea with a twist primitive (twist.dat ?). Perhaps it would be simpler if it were only in one octant: 2 24 0 0 0 0 0 1 2 24 0 0 1 1 1 1 2 24 1 1 1 0 1 0 2 24 0 1 0 0 0 0 POV code would be: //x - yz = 0 quadric { <0,0,0>, <0,0,-1>, (...) (20 years ago, 27-Apr-05, to lugnet.cad.dat.parts)

(...) Ok so it's been a few years, but I took another look at this. Did anybody ever make a twist primitive? It appears like all you need to do is something like this. Don 0 Wedge 4 x 2 Sloped Left 0 Name: 43721.dat 0 Author: Donald Sutter 0 (...) (14 years ago, 22-Sep-10, to lugnet.cad.dat.parts)

(...) Very interesting! (URL) I am not so much comvinced by the improvement for flat shading. Looks like we trade triangular artefacts in one direction with artefacts in the other one. But it drastically improves the very ugly condlines artefacts! (...) (14 years ago, 22-Sep-10, to lugnet.cad.dat.parts, FTX)

(...) Unfortunately it messes up unless you inlude FTX line breaks, or fixed code box characters (pipe). Unfortunately, both make it harder for people using email or newsreaders, so probably best to do it as you did, browsers can just click "View (...)
