Re: [osg-users] Render To Texture with osgFX

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, Look into osgHud and osgShadow for examples of RTT. You don't need osgFX, only a Camera and an FBO to set as the appropriate buffer, color or depth. You might want to use osgFX if multitexturing is involved when using the textures you generated.

If you want to just move the position of a texture on a fixed geometry, an alternative is to use a TexMat node (texture matrix) that will be multiplied with the texture coordinates. Updating is done just as Thibault suggested, with a callback. To see it in action check osgtexturerectangle exam
