You can use the setClearMask() function of the camera class. Normally you would 
provide the buffers which you want to be cleared. In your case you can just 
pass it a null or only clear the depth buffer. For example:

viewer.getCamera()-setClearMask(GL_DEPTH_BUFFER_BIT);

Hi Leandro,

The osg::Camera::setClearMask(..) is what you want to use.  Have a
look at the osghud example to see an example of it's use.

 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!
