Would a simple solution just be to move the conditional points right in
close to the original points at parse time? If the length of the conditional
vectors is unimportant then you’d be decreasing the number of conditional
points that lie outside the viewing frustum. With a distance of, say, 1/10th
LDU from the line you’d rarely encounter any problems.

So I think something along these lines (or a better works-mostly solution)
would be better.

I think you’re right. I’ll look into that. It seems like the most
straightforward, and since it’s just a pre-processing step, it shouldn’t affect
the performance for anything other than model loading.

It makes the "Show control points" option under conditional lines less useful, but that's a price I'm willing (...) (16 years ago, 14-Dec-08, to lugnet.cad.dev, FTX)

Eg. if you have a point that is directly behind its line in a perspective free (...) (16 years ago, 14-Dec-08, to lugnet.cad.dev, FTX)
