Re: [osg-users] Mutex and ReentrantMutex

Hi Paul, The difference is that ReentrantMutex will not block if the caller is already holding the mutex and is trying to lock() it again (there is a lock count maintained); you can therefore nest calls to routines using this type of mutex without fear of self-deadlocking the caller. With

Re: [osg-users] Fade in fade out effect

Do you want to fade to black, change scene, then fade up? Or do you want to fade from one to another? The first option is easiest, just draw a full-screen quad over the top of your scene, changing the alpha from 0 to 1. Then change scenes and reverse the alpha fade. If you want to blend between

Re: [osg-users] Fade in fade out effect

If you want to blend between scenes, when you're ready to blend, you'll have to render the first scene to a texture and draw it as a full-screen quad. Finally fade the quad from 1 to 0 to reveal the new scene. This means you'll be rendering both scenes concurrently during the fade, so

Add the camera to your scenegraph. Straight from the osgprerender.cpp example parent-addChild(camera); osg will find the camera and try to render using this camera as well. /Andreas Lindmark - Original Message - From: deepti g [EMAIL PROTECTED] To: OpenSceneGraph Users
