Before running these samples for the first time, it's recommended to run KGEConfig, which is provided by KlayGE, to complete the configuration first.

Distance mapping

Distancemapping

Distance mapping from chapter 8 of GPU Gems 2. In pixel shader, precomputed distance field is used to do local sphere ray tracing. The extension here is the silhouette can be presented well.

Techniques

1. Distance mapping
2. Silhouette detection
3. Normal map compression (since 3.4.0)

Requirements

• Geforce FX+ or Radeon 9500+. Geforce 6+ recommended.

Rendering plugin supported

• D3D11/OpenGL/OpenGLES2.
