I do not see the attachment. However, the PNG format can store 4-channel images (RGB plus alpha). I make these all the time with Gimp. You'll need to investigate how to create these with whatever image manipulation program you are using. -- Terry Welsh www.reallyslick.com Message: 6 Date: Tue

Re: [osg-users] Questions about OSG

not using OSG for is particles. OSG has osgParticles, but I haven't looked at it for a few years. It might have more of what I require now. I'm also using SDL and SDL_mixer. Together with OSG, these libraries reliably provide most of the heavy lifting of other game engines. -- Terry Welsh

Re: [osg-users] Cannot resize when rendering to FBO

Thanks Farshid. Camera::setRenderingCache() is the secret sauce. It works perfectly now. I hadn't come across that function yet, so I don't know if I ever would have found it. -- Terry Welsh www.reallyslick.com Hi Terry, I use osg::Camera objects to render FBOs that are the same size

Re: [osg-users] tight integration of virtual file system

suggestions? I still haven't tried converting everything to zlib in order to remove the libzip dependency. I'll get to that one of these days. Currently I'm trying to use this infrastructure to load my .wav and .ogg files, but that's not an OSG problem. -- Terry Welsh mogumbo 'at' gmail.com
