I'm trying to make HDR light, but not sure I'm on the right path. I use Accum buffers at the moment. Can someone tell me if this is the right method? Here is my first try Regards Sveinung

I thought it was usually done with a shader, theres an example that Ogre uses (see the compositor demo)

HDR is image based lighting.

Which is why its easier to use a shader (on the full rendered image)

Then I need to learn OpenGL shaders. Thanks allot. Sveinung

Are we talking about a simple Bloomshader or about real HDR?

Both... :) Sveinung
