[osg-users] Sidescan sonar image

[Dario Minieri]

Hi,

I would to implement a rendering pass which emulates a sidescan sonar. In practice I would to rendering an image of current frustum view "colored" in base to distance of objects.  Can you suggest to me a good way to achieve that? I think I have to work about depth map but maybe you can suggest to me some example which works around this problem. 

Thank you!

Cheers,
Dario
