hi all,
new mail, old problems...
good enough my cubemap is working... just it is 8 bit converted. I think
it isn't possible to take advantage of 16 bit framebuffers 4 the
visualization part yet.
Anyway, i'd like to extract the actual light infos from the image
itself... somehow. I think my target is to get the Y part out of the rgb
half values. Is it right? the formula is Y=R*w+G*w+B*w?? Y is the light
intensity radiated from that direction?
Difficult subject for my limited brain :)
thx all!!
