It turns out the internal coordinate-systems of some of the Quartz Composer geometric primitive patches are orientated in different directions. These two primitives have the X and Y coordinates of their vertices scales along the Z axis in model-space using a very simple GLSL Vertex Shader, but one appears to be rotated at 90deg. to the other along the X-axis. Odd.

I’ve been doing some work over the past year or so for Nicky Smith, AKA wierdcore, who, among many other things, is in charge of visuals for Aphex Twin’s live shows. Here’s some examples of some of my QC work in use.
Note: not all the QC work in these clips with carried out by me. You might recognise a few things from earlier posts here though.
