Dear Enrico,

i need to render my viewport to a texture,
and i was wondering how it can be done in opensg.
Possibly i'd like to "shot" a picture in 16bit floats.
Any ideas? I mined a bit into the old mailing list topics,
but could not find any clue. Thank you,
At the moment, I'm playing around with this and someone pointed the
rendertexture lib out to me (since I need to render into a floating
point buffer). It's available here:
http://www.markmark.net/misc/rendertexture.html
For Linux, you'll need the glew library
http://glew.sourceforge.net
as well. It basically provides a (sort of) capture mechanism to get
any arbitrary OpenGL stuff happening into a pbuffer instead of the
normal renderbuffer. Seems to work for me, however there also seem to be
issues (possibly just minor things I've overlooked since I didn't spend
more than a couple of minutes on it) like messed up depth.
If you manage with it I'd b glad to hear from any problems / solutions
you might come across :)
Best regards,
-.jan.-
