Hi there,
i'm trying to implement a basic depth of field effect in my scene
using the mipmap method.. (more on this here
http://ducati.doc.ntu.ac.uk/uksim/dad/webpagepapers/Game-18.pdf)..
I'd like to know if there is some way to grab the depth buffer via
opensg.. for what I know, this could be simply done changing the
current GL_READ_BUFFER from the TextureGrabForeground draw() method...
is there something ready to be used?
Thanks!
