What is rthdribl ?

Rthdribl is a "High Dynamic Range Image-Based Lighting" demo.
Technical features of the demo are:
True HDR (High-Dynamic Range) Rendering
IBL (Image-Based Lighting)
Glare Generation (Afterimage, Bloom, Halo, Ghost, and Star)
Automatic Exposure Adjustment
Iris shaped Depth of Field blur
Realistic Motion Blur
FSAA (Full-Scene Anti-Alias)
Fresnel Effect (Specular Reflectance) etc.
Glare, Motion Blur, Fresnel Reflection and Depth of Field effects work properly by rendering with HDR (see Fig.1-3).
Fig.4 shows the "Automatic Exposure Adjustment".
And Fig.5 images are are variety of Glare patterns that can be generated.
System Requirements

Intel(R) 80x86-compatible CPU
Microsoft(R) Windows(R) 98, ME, 2000, or XP
DirectX(R) 9.0 or later
A video card that supports Vertex Shader 2.0 and Pixel Shader 2.0
Additionary, D3DFMT_A16B16G16R16F and D3DFMT_A16B16G16R16 texture formats that can be rendered are highly recommended. If the current Direct3D driver doesn't support any floating point texture formats, Depth Of Field and Halo effects will not work. And if doesn't support any high-precision formats (at least 16-bit floating point or integer per component), both of image quality and frame rate will down.
