the same skull model but with a metalic texture and a new light enviromnent.
- What is rthdribl
Rthdribl is a technical demo of "High Dynamic Range Image-Based
Lighting". DirectX® 9.0 high-precision texture formats and
version-2.0 of Pixel Shader represent real-time true HDR rendering.
Light sources and reflected or refracted lights that are very bright
cause Glare.
Technical features of this 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 Reflection (Specular Reflectance, Metallic Color-Shift)
etc.
The Glare, the Motion Blur, the Fresnel Reflection and the Depth
of Field effects work properly by rendering with HDR.
These effects are still expensive for real-time rendering like
games, but will hopefully be of practical use in the near future.
- System Requirements
- Intel® 80x86-compatible CPU
- Microsoft® Windows® 98, ME, 2000, or XP
- DirectX® 9.0 or later
- A video card that supports Vertex Shader 2.0 and Pixel Shader 2.0
Additionary, 16-bit floating point per component and 16-bit
integer per component texture formats that can be rendered are
highly recommended. If the current D3D driver doesn't support any
floating point texture formats, the Depth Of Field and the Halo
effects will not work. And if doesn't support any high-precision
texture formats (at least 16 bits per component), both of the image
quality and the frame-rate will be down :-(
