[osg-users] Avoid cleaning drawing buffer

[Leandro Linardos]

Hi,

Is there any way to avoid cleaning the drawing buffer? 

I want to get a behaviour similar to the preserveDrawingBuffer in Three.js (http://threejs.org/docs/#Reference/Renderers/WebGLRenderer) to leave traces behind a moving object.

Thank you!

Cheers,
Leandro
