ingar@bibsyst.UUCP (ingar) (06/24/91)

 I have tried to program a ray tracing program, but now when 
i almost have finished I have discovered that my lines isn't lines,
they are curves! Can anybody help me??
If you have some source I would be glad.

I am not sure of this, but someone told me that gamma correction is used to
compensate for the curve of a monitor, so maybe your gamma correction is off
for your monitor.  Someone please correct me if I am wrong.

If straight lines look curved in your ray-traced images, you've probably got
your eye point too close to the viewplane.  Back the eye away from the
viewplane, and back the whole camera away from the scene.
