Hello performers,

I have an infrared camera image that I'd like to project into a scene
with other textured geometry. I would like to perform an addition
between the projected image and the textures on the geometry to produce
geometry texture that looks brighter (i.e. higher intensity) in the
'hot' (or white) spots of the infrared image. In the gl demo 'projtex.c'
blending of the textures is controlled thru direct manipulation of the
multipass process. Is there some combination of blending functions that
would give me this desired effect?

thanks for any and all help,

Dan
