Blur screen node
Posted: Sun Jun 01, 2008 12:32 am
Hi
I'd like to create a glow on a screen node with OpenGL (simple rectangle) it seems this can be done by RTT and GLSL shaders but I'm not smart enough to get it working
I'm wondering if anyone else has done something similar and can give an example of the .cpp and vert/frag (note: I don't want to use a billboard)
here is an example from FX Composer and the Nvidia shader library of the effect I'm after it does multiple passes and uses a glow-map RTT method:

Thanks Heaps
