Quartz Composer OpenCL Snow Leopard Tips and Tutorial: Heightfield with CL Kernel - with VideoImage Extrusion Example Composition
This video is a run down of some tips about some new examples files available at the Apple Developer Center website.
I take the text extrusion example, and show how to reconfigure it to use the OpenCL kernel setup to process video in a way that is similar to the Rutt Etra, or Kineme3D Heightfield, but which seems to work especially well with shadows (notwithstanding any other shadow limitations). This file is located at kineme.net/composition/gtoledo3/QuartzComposerOpenCLSnowLeopardTips HeightfieldCLKernelVideoImageExtrus ionExampleComposition
I also talk about and show the Apple 2d fluid example "2D Smoke.qtz", as well as the composition mesh warping and Interaction patch driven compositon "Pages Jiggle.qtz", and a small bit about how they work and are also part of the OpenCL zip from the Apple Developer Connection.
