If you are on RE2 or even better IR you could use texture paging from the frame
buffer (texture_copy) if the channel resolution is low enough.
This is how it works:
- Render the scene in one color channel
- Copy the framebuffer to texture
- Render back a polygon with the above texture and TLUT on.
TLUT could contain a transfer function, that if closed-looped with values of
previous frames could be used as gain control for the sensor.
Some people even use multiple bands of the sensor on single passes and
resolving multiple TLUTs to accumulate the results.
Also IR provides some additional features with hw acceleration (such as
creation of TLUTs from framebuffer content ...).
This is a common use of the TLUTs that is also being use by hw in the loop
arena and many other applications ...
On IR you could get extra bit resolution for some frame buffer visuals.
