Hi Robert,
any chance that you merge this into the next dev-release?
Hi Robert,
I've just implemented part of the GL_EXT_draw_buffers2 extension in
osg::BlendFunc, which is necessary especially for deferred shading
use. It enables developers to decide which of the multiple rendering
targets (MRT) can be affected by blending function. Those targets
disabling blending are always treated as to save extra geometry
attributes in all 4 channels rather than opacity.
This submissions is originated from the following topic in the mail list:
http://forum.openscenegraph.org/viewtopic.php?t=13057
And about the extension:
http://www.opengl.org/registry/specs/EXT/draw_buffers2.txt
A new osgblenddrawbuffers example is also submitted to show the
importance and usage of the new functionalities.
Cheers,
Wang Rui
