Holographic Radiance Cascades Demo

Holographic radiance cascades (HRC) implementation, with ray extensions and single-channel transmittance.

This is currently a poor demo of all of what this technique is capable of, due to a lack of brush color variation, but functionally shows radiance, occlusion, and volumetrics.

Controls:

• Left click paints light
• Right click paints semi-transparent occluders
• Escape to clear canvas
• Arrow Key Up/Period to render the next cascade up
• Arrow Key Down/Comma to render the next cascade down
