(...) Well actually what txt2dat does is a slightly different problem - it has a few simple closed loops and has to triangulate the complex polygons bounded by them (it uses the excellent (URL) triangle library> to do that). Renderers on the other (...) (18 years ago, 6-Mar-07, to lugnet.cad.dat.parts, FTX)

(...) OK, I stand corrected. Technically a program can fix things a load time. However, you might be surprised at how long it takes. It's "only" O(n^2), but each iteration is slow. You have to search the current line segment against all other line (...) (18 years ago, 6-Mar-07, to lugnet.cad.dat.parts, FTX)

(...) Well... Technically it is true. The rendering program ought to be able to scan all the points in each part and look for intersections with every edge in the part. Then break up the offensive T-joins automagically and render it perfectly. (...) (18 years ago, 6-Mar-07, to lugnet.cad.dat.parts, FTX)

(...) Arguably it's probably the algorithms and/or numerical proccessing that are at fault. Certainly when you design scientific code algorithms they should usually be created in such a way that it minimises numerical error. Of course I don't expect (...)

(...) I'd really appreciate it if you didn't blame it on the rendering programs. There's really nothing that they can do to fix the problem. I can understand why you might feel that they are at fault, but it really isn't true. As such, you might (...) (18 years ago, 6-Mar-07, to lugnet.cad.dat.parts, FTX)

(...) I try to minimise file size whenever possible myself and have nothing against T juctions. While the gaps can be annoying I feel that they are a fault of the rendering program rather than the parts. (18 years ago, 4-Mar-07, to lugnet.cad.dat.parts, FTX)

Well I submitted my entry: (URL) It was pretty fun, and I got to teach myself a few more POV tricks (like loops mainly). Nothing was changed in the MPD and I used L3PAO to convert to POVRAY and then I used Mesh-Enhancer on the minifig's hair to (...) (18 years ago, 6-Mar-07, to lugnet.cad.dev.org.ldraw)
