This repository is a collection of assorted demos and examples using openFrameworks. There is no theme, except that they each demonstrate a technique that doesn't really fit in any other repository.

• BarnesHut: basic 2d implementation of the Barnes-Hut quadtree particle system optimization, good for simulating large force-at-a-distance systems.
• BinnedParticleSystem: basic 2d binning optimization for particle-particle interaction.
• BulgeEffect: magnification effect with GLSL for generating and applying the displacement map.
• BulgeEffectMulti: magnification effect for many points by rendering displacement images into a big displacement FBO before applying them.
• GLSLParticleSystem: example of using shaders to compute one-to-many interaction.
• LutExample: applying a 3-channel lookup table to a live stream using a fragment shader.
• NoiseFlocking: "Clouds are Looming" style noise flocking simulation.
• P52OF: port of a simple noise flocking simulation from Processing, done by pasting the code directly and creating a PApp class that wraps OF to make it look more like Processing.
• RemapExample: per-pixel displacement example using a fragment shader.
• VideoRecorder: demonstrates how to use ofxQTKitVideoGrabber on OSX to preview a webcam feed, record a video, and then load and play it back.
• VideoShuffler: loads a collection of videos from the videos/ folder as specified by the videos.xml file.
