(...) Not that I know of. I'll think about adding a page to the LDView web site. (I don't think it's really appropriate to add it to ldraw.org, since it's LDView-specific.) (...) The precision is 0.0001. I multiply the coordinate by 10000 and then (...) (16 years ago, 11-Dec-08, to lugnet.cad)

Has anyone been working on this? I used the Peeron partnumber, would that be correct? I have determined that the shape of the "body" of the drill is extremely close to 5+(x+3)^(1/1.58), does any primitives exist that are useable for such a curved (...)

(...) Thanks, Travis. BTW, are there guidelines for part authors that would improve smooth shading? What about precision in coincidence between conditional lines and matching polygon sides? I have seen _many_ instances where a quad should blend into (...) (16 years ago, 11-Dec-08, to lugnet.cad)

(...) I looked at LDDP sources (very clear BTW!). Threshold is compared against square of cross product of each angle of quad. So it depends of size of quad to 4th power! Not very good imho, but since it works for such a long time I used the same (...) (16 years ago, 11-Dec-08, to lugnet.cad)

(...) It depends on what your threshold is but taking the difference (as you do in a cross product) of two big numbers is less accurate (very much so sometimes) than taking the difference of two smaller numbers. Even without this issue it means that (...) (16 years ago, 9-Dec-08, to lugnet.cad)

(...) No, I just take the cross product, and if the length (squared) is 0, I give an error. I don't see how normalizing the length of the two vectors that I feed into the cross product would improve things much here. Sure, it might mean that my (...) (16 years ago, 9-Dec-08, to lugnet.cad)
