Experimental real time 2D raytracing with various applications.

Render pipeline compatibility

The Built-in Render Pipeline is Unity’s default render pipeline. It is a general-purpose render pipeline that has limited options for customization. The Universal Render Pipeline (URP) is a Scriptable Render Pipeline that is quick and easy to customize, and lets you create optimized graphics across a wide range of platforms. The High Definition Render Pipeline (HDRP) is a Scriptable Render Pipeline that lets you create cutting-edge, high-fidelity graphics on high-end platforms.

Additional compatibility information

Fragment shader implementation, so performance is highly resolution-dependent. Optimal resolution is 720p or lower. Performance and various applications can be teseted in WebGl demo.

Real time 2D raytracing that can be used for realistic lighting or for creating visual effects, via various settings configurations.

Raytracing works as post effects applyed for objects rendered by LayerMask, that can be rendered directly in to the camera or to the global texture.

This is fragment shader implementation that sould work on any devices because it doesn't use compute shaders and other platform depended stuff. But performance highly dependent on screen resolution.

Technical details

Real time shadows, ray bounces, custom light shapes

Light count don't affect to perfarmance

Fixed resolution for Pixel Art

Settings can be controlled at real time via post process volume or script

Can be used for abstract illustractions or stylized for specific tasks
