Toxiclibstoxiclibs
is an independent, open source library collection for computational design tasks with Java & Processing developed by Karsten “toxi” Schmidt (thus far). The classes are purposefully kept fairly generic in order to maximize re-use in different contexts ranging from generative design, animation, interaction/interface design, data visualization to architecture and digital fabrication, use as teaching tool and more. Browse to some examples.

Download Blob Detection library and install (NOT GOOD)
- Download the BlobDetection package.
- Close Processing if it is running.
- Create a folder called blobDetection in processing's libraries folder. Inside this folder, create a library folder.
- Copy blobDetection.jar in this new fresh folder.
- Launch Processing, a new menu item blobDetection should appear in Sketch/Import Library.
- You can manually insert and use the library by inseting the foloowing on top of your main.

GLGraphics Library
SelfPortrait with GLGraphics Library of Processing folder
GLGraphics is a library intended to extend the capabilities of the OPENGL renderer in Processing. It includes classes to handle opengl textures, image post-processing filters, 3D Models, and shaders in GLSL, Cg and CgFX. It also includes an offscreen rendering surface with antialias support. Look at the examples below for the details on how to use GLGraphics.
Study the classes of the library
GLTextureFilter intresting link After you define an object you create with the dictionary
GLTextureFilter pulse, zMap; pulse = new GLTextureFilter(this, "pulsatingEmboss.xml"); // at setup
The .xml file has the following structure
<filter name="pulsating emboss"> <description>Dynamic emboss convolution filter with pulsating vertex grid</description> <vertex>PulseGrid.glsl</vertex> <fragment>DynEmboss.glsl</fragment> <textures input="1" output="1"></textures> <grid mode="direct"> <resolution nx="10" ny="10"></resolution> </grid> </filter>
