It’s worth noting that if you get the POV-Ray camera info from LDView and render in POV-Ray, you should get exactly the same view there (assuming you use the same aspect ratio).

I was thinking of that. I tried it briefly the other night but I must have had a different aspect ratio, because the rendering appeared far outside the ship. I’m getting up to speed on POV-Ray, though, so I’ll definitely try it again.

  
   Travis, since I already had the LDView code set up I reduced the strafeAmount and motionAmount values used in ModelWindow::processKeyDown to 0.05. This made it much easier to make fine adjustments to the camera position; even smaller values may be useful. Perhaps it would be worth adding a Preferences setting to control these values?

The sensitivity is pretty messed up. It doesn’t properly track the frame rate, so if you have a high frame rate it goes too fast, and if you have a low frame rate, it goes too slow. I think the proper solution would be for me to fix that.

Ah, I see. Sounds good. Yes, initially the camera would jump across or out of the cockpit at the slightest touch. I changed the value so I could nudge it around easier within that area.

If you have the same aspect ratio, you should should get nearly pixel-perfect alignment of all polygons that don't (...)
