<h2>Description</h2>
<p>This sample demonstrates using OpenGL to composite multiple sources in hardware. It requires NVIDIA GeForce 4 Ti hardware for full functionality. The compositor lab operates on graphic content in various layers allowing one to apply blending effects to each separate layer. One can select layer by clicking on it's content (which can also be moved by dragging the actual content). Layers can be added via the Open menu or by dragging and dropping images or movies directly on the content window. Effects are controlled by the info panel activated via the Tool menu. Comments and bugs are welcome at: <http://developer.apple.com/bugreporter> Requirements: GeForce 4 Ti, ProjectBuilder, Mac OS X 10.2 or later. Keywords: OpenGL, Cocoa, quicktime</p>
