(...) I understand that. But the question specified that the number of triangles (actually polygons, but feel free to assume triangles) is fixed. (...) So size of the polygons doesn't matter. Hmm. I'll have to remember that. Steve (22 years ago, 3-May-02, to lugnet.cad.dat.parts.primitives)

I don't know about all situations (POV, etc), but for real-time rendering in OpenGL, the fastest rendering generally occurs with the fewest number of triangles (assuming that the triangles specify the same final geometry).

(...) Not necessarily. We usually stick with units of 1 because they're the most easily scaled, and most easily implied (ie, if every ring has a n:(n+1) ratio of radii, we don't need to state both radii in the filename). OTOH, boxes have side length (...) (22 years ago, 3-May-02, to lugnet.cad.dat.parts.primitives)

Hi Everyone, Been a while since I've visited :) I noticed the two parts I submitted last year are still under review. I have fixed the duplicate line in 30046 'Window 1 x 2 x 2 & 2/3 Pane Lattice Diamond with Rounded Top'. I will resubmit that soon. (...) (22 years ago, 3-May-02, to lugnet.cad.dat.parts)

(...) Yes, otherwise you get anomalies like this one: (URL) the outer ring of the tile got high-quality-ified but the fill in (non primitive?) circle didn't, leaving gaps.
