OptiX Toolkit Examples

Example programs demonstrating features in the OptiX Toolkit.

See the CHANGELOG for recent changes.

Simple examples

• OtkHello, a simple "hello, world" example for the OptiX Toolkit.

Demand Loading examples

• DemandLoadSimple shows basic demand loading of resources by page id.
• DemandLoadTexture demonstrates demand loaded textures on multiple GPUs.
• DemandGeometryViewer is a simple demand loaded geometry example.
• DemandPbrtScene uses demand geometry, demand materials and demand textures to render a PBRT scene.
• DemandTextureViewer visualizes texture tiles loaded from a mipmapped texture.
• TextureVariantViewer shows two textures with the same backing storage. One texture uses linear interpolation, and the other uses point interpolation.
• RayCones demonstrates using ray cones to drive texture filtering.
• udimTextureViewer demonstrates demand loaded udim textures.

OmmBaking examples

• ommBakingSimple is a simple example of opacity micromap baking and creating an OptiX triangle primitive acceleration structure using the micromap. No rendering is performed.
• ommBakingViewer is an interactive viewer for a scene using opacity micromaps.

Libraries

• pbrtParser wraps a pure virtual interface around the PBRT scene file parser from pbrt v3.
• PbrtSceneLoader parses a PBRT scene file into a simple scene description.
