We are writing a periscope simulation and are currently having problems with Z
fighting.
We are running on an InfiniteReality2 with 1 RM9 Raster Manager and are drawing
to
two displays which both use the same area of the framebuffer ( one virtual
binoculars
1280x1024 180Hz field sequential, the other is a standard monitor 1280x1024 60Hz
).
For the application we need to use an accumulation buffer. The visual that fits
our
needs best is the following ( from findvis). We are using Medium pixel depth
0x6b, RGBA 12/12/12/12, db, Z 16, accum 25/25/25/25, samples 4
Unfortunately that only gives us 16 bits for the Z buffer, and due to the
application
we need to have the near clip plane at 1m at the far clip plane at 50,000m.
Is there a way we can change the framebuffer configuration to reduce the number
of
bits per component in the accumulation buffer and use them to increase the bits
in the
Z buffer?
Any help would be greatly appreciated.
