Post-processing filters are easily implemented using the Filter object. You
draw tour scene normally but draw calls are surrounded by a `with
Filter(shader) where the shader transform the output.
- filter-pixelate.py
- Pixelating filter with pixelation level controlled by mouse scroll.
- filter-blur.py
- Simple 2D Gaussian blur using two 1D kernels.
- filter-compose.py
- This example show how to compose filters together.
Note
You will find several other very nice filters in the GPUImage repository.
