can you tell me what is the HDR exzactly? does it only affect the lighting, or what is affected by it in this video?

[suddensunden]

The environment/cube map is a High Dynamic Range Image, which means that it was acquired with a wider range of values. This makes the values for lighting in the image more accurate. You can't display a HDR image on a normal computer screen because it's dynamic range is too low. So that's why you need to use tone mapping and map the HDR values to LDR values in different ways. For instance, you can adapt the toning so you see what lies in the dark or light areas more clearly.

Ported DirectX dev sample with misc objects added. Oh well, cool. When's the committee gonna release next GL version then? :)

[suddensunden]

Really, I didn't know.

Do you gotta a link?

Much of the shaders i basically just from the OpenGL SL book. Some on the other hand is pure image proccessing with the standards of a game developer, meaning fast but not accurate ;).
