Detailed Description

Sampler built on top of a CGBitmapContext to allow deformable geometry.

Very efficient when paired with a ChipmunkTileCache.

Method Documentation

Initialize a context based sampler.

Must provide options for a valid context. Find out more here in the Quartz 2D Programming Guide.
