extrusion

contrast image extrusion

fiebigc's picture

hey, i'm new to qc and kineme - and well i just want to get something to work like every stupid newbie :)

so my question is: is it possible to extrude black areas of a high contrast image to an 3d object - which also could be manipulated by a noise patch?!

I'm looking for it for quite a while but maybe it's really simple and I just can't see the forest for the trees?!

I really would appreciate any hint or help!

This video is a run down of some tips about some new examples files available at the Apple Developer Center website.

Then, I take a 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).

I also talk about and show the Apple 2d fluid example, "2D Smoke", and the composition "Pages Jiggle" in action.

This is a composition that makes use of the Kineme3D HeightField patch and particle systems. It can achieve a fairly wide variety of looks, including very liquid like objects, flows, spiky textures, light beams, tunnels, wire frame, and GL Point based particle systems.

This is a composition that takes an image and warps it using GLSL, a Sphere renderer, and Kineme3D HeightField. It also incorporates Kineme GL Tools Polygon Mode.
