No. The way that conditional lines work is that if the two control points lie on the same side of the conditional line on the screen (in (...) (16 years ago, 14-Dec-08, to lugnet.cad.dev, FTX)

(...) 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 (16 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 (...) (16 years ago, 14-Dec-08, to lugnet.cad.dev, FTX)

After messing around for a few months, I gave up and began working on the EMU. Now that I have almost finished the EMU, I have worked out how to do the nose of the SMU. (URL) should be public soon - I hope. (16 years ago, 14-Dec-08, to lugnet.trains)

(...) OK, round 3. The black background is just due to the fact that I rendered it with an alpha channel so it is transparent. My animation software made this black by default, but it is easy to change. So with that in mind.... I've made a new one (...) (16 years ago, 14-Dec-08, to lugnet.technic, FTX)

(...) 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 (...) (16 years ago, 13-Dec-08, to lugnet.cad)
