Showing off Virtools™ 4's high end rendering capabilities, this car demo illustrates some of the latest real-time HDR Rendering techniques using multiple shaders. Some of the HDR Rendering features include floating point texture and render target, tone mapping, natural eye adaptation (auto exposure) and glow. This demo also shows Virtools 4's image based lighting shader capabilities, using an environmental texture to compute the car's lighting.

Application: Technical Requirements, Controls and Settings

• WARNING: This demo may not be viewable on all PCs. DX9 and at least a VS_2.0 shader-compliant graphics card is required! Your graphics card must be able to support:
  • Shader model 2.0
  • Floating-point 64-Bit HDR texture render (format: A16B16G16R16F)
  • IEEE Floating-point 32-bits textures (format: R32F)
  • 8 Pixel pipeline is recommended for better performance.
    
• Controls
• Press Tab, Enter or Spacebar to activate the options menu.
• Press Esc to quit the demo.
