An additional question about
fog:
Again,
density seems to have absolutely no effect.
Given
a scene with a static "fog end" distance, as the "fog start" distance is
set closer and closer to the camera, the fog gets thinner and
thinner.
Is
there a finite number of fog density steps [256?] that are used to span the
space between fog start and fog end? This would explain the thinning as the fog
span gets bigger.
Is the
fog rendered differently in directX and openGL?

Rob
Hello,
Can
someone elaborate on the fog in Virtools?
The
density setting seems to have no effect.
The
fog end value acts like a camera clipping plane [nothing is visible beyond
it].
Is
it possible to set a ceiling for the fog?
The
sample recently posted [re:multitexturing and fog] seems to have fog with a
ceiling. Is this simply an optical illusion?
I am
experimenting with using particles for fog so I can control it and make it
dimensional. Has anyone else tried this with success?
Regards,
Rob
