Last week I had a chance to be a special guest for the final presentations in Patricio Gonzalez Vivo's GLSL class at Parsons. One of the big take aways from the class was how versatile the language is, with students presenting projects ranging from web based mapping to 3D Unity worlds, realtime data visualizations in openFrameworks, and of course for live visual performance, all driven using GLSL.
One project in particular from student Udit Mahajan of course caught my eye, an A/V performance made using ISF compositions in VDMX, feeding into Unity3D and running alongside Ableton Live creating music.
If you're interested in seeing more about what the class got up to with GLSL, the git repository for the class is online here: https://github.com/patriciogonzalezvivo/ss2015
For anyone looking to learn GLSL, Patricio has started writing an online based textbook “The Book of Shaders” which is a great place to get started. The book has even already been partial converted into ISF for use in VDMX or in the ISF Editor tool.
