How to make blur vision?


I'm trying to get the effects of visual impairments or low vision when users seeing scene from HMD. I'm looking for a way in the render system of vizard to blur objects far from users. I tried previous post solution:, but have following problems:

1. I prefer a non-uniform blur which makes further objects more blur.

2. I need this effect to work in stereo.

3. When I ran this script, I got the error said "before Font::Glyph::subload(): detected OpenGL error 'out of memory".

The system spec:
Microsoft Windows XP, 32-bit (Service Pack 3),
DirectX version: 9.0c,
Vizard 3.13.0002

NVIDIA GeForce 8800 GTX -
Driver version: 185.85
Stream processors: 128
Core clock: 576 MHz
Shader clock: 1350 MHz
Memory clock: 900 MHz
Memory interface: 384-bit
Memory: 768 MB

Thanks a lot!

Hello again,

Maybe the better way to think about this blur thing is how to manipulate depth of field. I know our graphic card supports real time depth field effect. Is there any way that vizard render system uses opengl depth field implementation to get blur effect? I'm not sure what I really expect. Uniform blur might work too.
