(...) If I understand correctly you shouldn't be checking on the projection, only on the full 3D transformed points. That means you should check after stage 2.5. You'll need the Z value to work out which side things lie on. Tim (18 years ago, 14-Dec-08, to lugnet.cad.dev, FTX)

(...) I think I need help. I thought I was using gluProject for the conditional calculations, but discovered that I'm not. I multiple the projection matrix by the model-view matrix to get my transformation matrix, then run the points through that to (...) (18 years ago, 14-Dec-08, to lugnet.cad.dev, FTX)

(...) Looks like you found another LDView bug ;-). Zoom out and it works fine. It only doesn't work when the control points are clipped by the edge of the window. I'll have to figure out a way to fix that. (...) It's difficult, but by using polling (...) (18 years ago, 13-Dec-08, to lugnet.cad)

(...) Hopefully you have primitive substitution set to two (second notch), since 1 provides 8-sided circular primitives. As for separating the stud logo from the primitive substitution, the logo is an implicit part of the substituted stud. It's not (...) (18 years ago, 13-Dec-08, to lugnet.cad)

When the curvature is the only concern, then yes, but I have to take the screwshape into consideration, the closer I am to the ideal curve, the easier it is to calculate the screwshape and avoid holes in the part.

I made a quick try - and it doesn't work very well, even when it should (between a cylinder and a cone). Example: (URL) (cedge primitive is here included). Cedge seems to behave correctly on the more sloped cone, but not on the other, it appears (...) (18 years ago, 13-Dec-08, to lugnet.cad)
