Hi Rahul. If I recall correctly the color matrix isn't working on most
consumer cards. You need the the GL_ARB_IMAGING extension.
Alternatively you can achieve the desired effect with a shader.

Hi all,
I am trying to use OpenFL color matrix functionality through
osg::ColorMatrix but
Hi Ulrich,
Thanks for the reply, you are absolutely right, color matrix is part of
imaging subset which is used during pixel transfer operation. The
concept just slipped out of my mind ;)
thanks for the correcting my thoughts

Color matrix in OpenGL is used for color space conversion, for example
using color matric you can convert RGB to BGR , RGB to CMY.
Unfortunately i do not have any screen grabs for the moment, but i am
trying to achieve night vision effect using this code ,
