Inheritance diagram for gutz::Camera:

gutz::BaseManip gutz::Counted gutz::Light List of all members.

Detailed Description

The "LOCAL" space for this manipulator is WORLD space.

This object maintains the Projection and View matricies. It also handles VIEWPORT transforms implicitly, you can take SCREEN space points (0-SX)(0-SY)(0-1) and get them either in EYE space or WORLD space. Where:

Tranformation chains (for Manip) interface Manip basically implements a linked list of manipulators that can be strung together.

If you set your parent to be 0, then you effectively nuke the chain above this manipulator. Cameras are special, there can only be one, and it is always at the very top of the chain (ie has no parent). See gutz::Manip for the rest of this interface
