NoiseGLSL Noise and Extrusion - KinectI made a blog post about setting up a GLSL shader to do an extrusion function and noise function, inspired by the gl point/noise look of the cool plugin from _1024 / franz, posted yesterday, setup for using the kinect tools output. http://www.georgetoledo.com/2010/12/glsl-extrusion-and-noise-example-kin... Hopefully, the shader based approach is of use, and is a good jump off point for customization. Many thanks to franz for the inspiration on look; I'm saying happy holidays with another "snow storm"! :) Letter Noise (Composition by gtoledo3)
This is a bit of a double post: I'm posting a non-Value Historian version of this "Letter Noise" qtz that's based on Chris's sample for Freeboard, so that it can be pulled up from the Repository. I think it's a neat twist on integrating audio reactivity and typography with one another. It needs Kineme3D as well as Freeboard to work. Perlin Noise CIKernel (Composition by smokris)
Here's a CIKernel implementation of the Improved Perlin Noise algorithm, based on the reference implementation http://mrl.nyu.edu/~perlin/noise/ . Drop "Perlin Noise CIKernel.qtz" into "perlin.qtz" is an example of how to use it. This is fairly inefficient, as Core Image Kernel Language doesn't support arrays (!), so I ended up dumping the Perlin permutation array into an image (see "perlin-tga.c") and then loading the image into QC and sampling it. Suggestions regarding how to improve performance are welcomed. |
