What is rthdribl ?
|
Rthdribl is a
"Real-time High Dynamic Range Image-Based Lighting" demo.
DirectX(R) 9.0
high-precision texture formats and version-2.0 of Pixel Shader
represent real-time true
HDR rendering.
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.
The Glare, Motion Blur, Fresnel Reflection and
Depth of Field
effects work properly by rendering with the
HDR
(see Fig.1-3).
Fig.4
shows the
"Automatic Exposure Adjustment".
And
Fig.5
images are are variety of the
Glare
patterns that can be generated in the demo.
These effects are still expensive for real-time rendering like games,
but will hopefully be of practical use in the near future.
Enjoy the future real-time rendering!

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 the image quality and the frame rate will be down :-(

Tips
|
Maybe you feel that frame-rate is slow.
Follows are some tips for increasing the frame-rate.
- Disable Multisample
- Disable Depth of Field effect
- Change "Glare Type" to "Natural"
The demo loads initial setteings from
rthdribl.ini
or the first command line argment of
rthdribl.exe.
Please make reference to
rthdribl.ini
and
rthdribl_large.ini.

Problems
|
- Cause system crash on some enviroment with fullscreen mode.
Cause of this problem is unknown.
Running with windowed mode is recommended.
- To drag-and-drop the .ini file to rthdribl.exe may cause an application error.
Cause of this problem is unknown.
