Detailed Description

Each VEX shader can have a transform bound to it. This transform is used by the ptransform(), ntransform(), etc. functions to look up "world" or "object" space.

Variables in the shader are defined to be in "current" space. The CVEX context allows you to specify various transforms from the current space to another space. The other spaces are defined by the built-in VEX spaces:

• "space:world": Transform current space to "world" space
• "space:camera": Transform current to "camera" space
• "space:object": Transform current to "object" space
• "space:light": Transform current to "light" space

It's also possible to specify a "lookup" helper class which can be used to look up user defined spaces.
