HDR Tone Mapping Technique

post

about

In 3D Computer Graphics, high dynamic range rendering (HDRR or HDR Rendering), also known as high dynamic range lighting, is the rendering of computer graphics scenes by using lighting calculations done in a larger dynamic range. This allows preservation of details that may be lost due to limiting contrast ratios. Video games and computer generated movies and special effects benefit from this as it creates more realistic scenes than with the more simplistic lighting models used.

Tone mapping is a technique used to map colors from high dynamic range (in which lighting calculations are performed) to a lower dynamic range that matches the capabilities of the desired display device. Typically, the mapping is non-linear - it preserves enough range for dark colors and gradually limits the dynamic range for bright colors.

notes: All PS and VS to 3.0. hope this fixes ATI cards problems

sounds great but its all black on ati with vvvv23...

awesome, buddy! :)

@hrovac: try setting all compile targets to ps/vs 3.0 model by editing the appropriate lines in the shaders. e.g.:

VertexShader = compile vs_1_1 VS();
PixelShader  = compile ps_2_0 PS();

becomes

VertexShader = compile vs_3_0 VS();
PixelShader  = compile ps_3_0 PS();

i have no ati here right now to try it on this shader, but this generally worked for me on most shaders.. (ati fx compiler is said to be more strict than nvidias)

Brilliant!

thanks guys, i'm sorry about ATI problems. i'll just recompile all the shaders in 3.0.
