High Dynamic Range Effects

This project has the following features and post-processing effects implemented:

• High Dynamic Range environment maps
• Global tone mapping using parallel reduction to compute the average luminance at each frame and auto adjust exposure
• Cubic lens distortion
• Lens flare approximation
• Bloom effect
• Refractive shader material

The source code is available under MIT license on github.

Cubic lens distortion shader with chromatic aberration:

Procedurally generated texture used for sampling the lens flare starburst, it's a kind of radial noise that jitters the bloom to approximate glare:
