Hi everyone, I have a simple question regarding pre/post render cameras:
- suppose I have a scene graph under a viewer camera - the scene data for this camera starts with a root group. - somewhere in that root group, I add a pre_render camera, to render a texture on an FBO, and as a child of that pre render camera... I use the root group itself !... What would be the behavior in that case ? - Would OSG notice that the pre_render camera is to be rendered before but render it only once - Or would OSG fail to notice this and prepare "pre-pre-pre... pre-render" stages forever ? (and actually freeze completely) ? Or is there a way to achieve what I want to do here properly if this option is known to block ? Basically, I want to render a "World view camera" but also the view of a helicopter embedded camera on the complete world... (and the helicopter itself is in the world obviously...) Cheers, Manu.
