ofxPostProcessing
This openFrameworks addon gives you an easy way of putting together a chain of GLSL post-processing effects.
www.neilmendoza.com/ofxpostprocessing
Features
At the moment, it comes with the following effects (some ported from other sources and some original) that I'll gradually add to over time:
- Bloom
- Convolution (Blur)
- Depth of field (with bokeh)
- Depth of field alternative (more features but heavier)
- Frei-Chen Edge Detector
- FXAA anti-aliasing
- Kaleidoscope
- Noise warp
- Pixelate
- SSAO
- Toon
- Godrays
- Tilt shift
- Fake subsurface scattering
- Many others, please see src directory
Usage
In your OF app declare an instance of ofxPostProcessing...
ofxPostProcessing post;In your setup() function initialise the post-processing class and then add some effects...
post.init(ofGetWidth(), ofGetHeight());
post.createPass<FxaaPass>();
post.createPass<BloomPass>();Call post.begin() and post.end() around the the scene that you want to render...
post.begin();
<RENDERING CODE>
post.end();If you are using an ofCamera pass this to post.begin() and it takes care of the rest for you...
post.begin(cam);
<RENDERING CODE>
post.end();TODO
- Add support for ofGLProgrammableRenderer with version 150 shaders
- More FX
- OpenGL ES, it's based around power of two textures so it should be fairly quick to get working.
