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

  • More FX
  • OpenGL ES, it's based around power of two textures so it should be fairly quick to get working.
