Core Animation culling problems / 3D layers

On the Parmanoir blog (creator of JSCocoa), we can find a rework of the Core Animation NanoLife example originally developed by Theocacao’s Scott Stevenson (particles dispatched on animated layers, 80 total), as with goal to describe these particles in 3D. The encountered problem (layers ordering with the new z dimension, that is ignored by Core Animation) seems to have been resolved by Scott Stevenson (provided the fix), and Core Animation behaviour finally seems right.

The orginal article provides interesting informations on these subjects : Core Animation and Core Image filters, conversion between NSImage, CIImage, and CGImageRef, full screen mode for NSView.
