Round primitives with x/48 fractions - using 16 segs - Tim Gould - 2012-04-02
Hello people/LSC Since it is perfectly possible to make the x/48 (eg. 7/24, 1/6 etc.) primitives on a 16-sided polygon (using eg. my little perl script) provided care is taken (another approach would be to make 1/48 and 2/48 wedge parts that fill in the gap) I was thinking it might be nice to cut the restriction to using 48 sides for such fractions. In particular parts like 30632 would not need such a huge number of faces. What do you think? Tim Re: Round primitives with x/48 fractions - using 16 segs - Philippe Hurbain - 2012-04-03
I don't think it would work well, because when you try to rotate such primitives by 7.5 degrees (1/48 turn) they would not match properly other normal resolution primitives (or you would need to have three times the number of primitives, rotated by 0, 7. 5 and 15 degrees). The wedge 1-48/1/24 approach may be more workable. For the 30362 part (and a lot of similar parts), what I'd like to see is "mixed mode" tori primitives: they would be hires (48 segments) on major radius, 16 segments on minor radius.

Hi Philo, Yes I agree about the rotation, but making just a 1-48 and 1-24 would cover all cases with the existing primitives. Also agree about the torii. Not that it matters a huge deal, but it could be nice. Tim |
