|
At what angle and point do the arm/shoulder of the minifig connect to the torso? What is the angle and offset of the bend of the minifig arm and what is the angle of the hand with respect to the pin which connects it to the arm? I don't see how (...) (25 years ago, 5-Apr-00, to lugnet.cad.dev)

(...) This points out that ray traced renderings of the transparent version of these pieces will not render the refraction correctly. In the best of all worlds, the interior surface would be removed. For ray tracing, the model could be replaced with (...) (25 years ago, 5-Apr-00, to lugnet.cad.dev)

| | New Part: Castle Shield with Black Falcon Pattern [DAT]
|
|
I have taken the opportunity to split out the non-decorated surface into a subpart in line with current practice for decorated parts. For this part I have hardcoded the shield as grey, so that the part colour controls the border - blue or yellow. (...) (25 years ago, 5-Apr-00, to lugnet.cad.dat.parts)

(...) I suspected this problem when I reviewed the precision of all the circular primitives, which is why I left them alone at that time. But... I never went back to check thoroughly! Chris (25 years ago, 5-Apr-00, to lugnet.cad.dev)

(...) That's is the (Odd/Even) test, also with Raycasting, but no supersampling, in the supersampling case, you just subdivide the polys further and further, or shoot pseudo-random rays until you find the correct normals for all faces. this does NOT (...) (25 years ago, 5-Apr-00, to lugnet.cad.dev)

(...) Perhaps this approach is a bit naive, but couldn't you use something similar to a point in polygon test? Cast a ray along the normal from the center of each polygon. If it intersects an odd number of surfaces then the normal points toward the (...) (25 years ago, 5-Apr-00, to lugnet.cad.dev)

Is it just me or the sphere primitives have non planar quads ? Or is the sphere distorted to allow for planar quads ? Why where the sphere done in this way instead of the usual (full quads with triangles on the poles) or (all triangles) ? I hope (...) (25 years ago, 5-Apr-00, to lugnet.cad.dev)
