Re: [osg-users] Dynamically changing all textures in a scene

Regarding the option 2: Post process the rendering back end's osgUtil::StateGraph replacing StateSet after the cull traversal has run. Where would the point of intervention be to get access to the stategraph, in order to change the different statesets? Linus

Re: [osg-users] Dynamically changing all textures in a scene

A long long time ago somebody posted source code for osgDepictions, which allows you to do a texture/stateset switch for a complete scene. I could not find it in the mailing list archives though... -- Roland -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On

Re: [osg-users] Dynamically changing all textures in a scene

The proper way to go about this would be using an alternate shader for the infrared view. That way you can pull in any source texture (one that is already mapped on an object), and generate the infrared composite image on the fly. For example, if you want all of the walls (and other cold
