[osg-users] How to simulate camera distortion ?

[Robert Osfield]

Hi Jishen,

Have a look at the osgdistortion example, this use a render  the 3d
scene to a texture, then a rendering this texture to the screen using
a distorted mesh.   Alternatively you can do wha Bjorn suggested and
use a simple quad and shader to do the distortion during the second
pass.
