(...) Yeah, me too, but opengl requires it. I didn't make them automatic because the ldlite parser draws as it parses, so it doesn't have access to the bounding box of the model. I'll fix it for the l3 parser to default the clipping planes just (...) (20 years ago, 25-Oct-04, to lugnet.cad.dev)

(...) I just wasn't sure what to do with -z and -Z. LPub has to manage ROTSTEPS and such, so it pre-rotates the model into the desired view angle. It also centers the model in the process. The default value of -z10 clips the front of the car off. (...) (20 years ago, 25-Oct-04, to lugnet.cad.dev)

(...) Yeah, that 60000 number plays havoc with a bunch of things. You get a lot of z-bleeding because the clipping planes are spread so far apart. Maybe I get less depth bits on the offscreen buffer. Gotta check. And I suppose I should borrow the (...) (20 years ago, 25-Oct-04, to lugnet.cad.dev)
