Preparation

1. Install sibylengine following its setup instructions.

2. Download the scenes and place them in the /scenes folder.

3. Run the examples:

   • Open the vvmc folder in VS Code.
   • Activate the Python environment where sibylengine is installed.
   • Execute main.py in each example folder.

Examples

• example-rglmat: ratio control variates for BRDF sampling. A material ball with RGL measured BRDF under uniform environment lighting. The material can be switched in editor.
• example-lightbvh: ratio control variates for many-light sampling and MIS. Direct illumination only. 3 test scenes can be switched in main.py.
• more examples later...

Play with the editor
