Some screen space image effects implemented in Unity3D.
Some of the effects are demonstrated on a still from Big Buck Bunny, (c) copyright 2008, Blender Foundation / www.bigbuckbunny.org.
Currently Implemented:
- Edge detection shader
- Supports 3 sampling kernels (Sobel, Scharr, Prewitt).
- Either display the gradients or add or subtract those from the input image.
- Pixel based cel shading effect by limiting the number of available colors.
- Multi-pass Gaussian blur, support for varying radius and standard deviation.
- Bloom, using the Gaussian blur to create bleed-over from bright parts of the image.
Display of the gradients as found by the Sobel filter
