A FrustumCam is a mixin that provides for frustum (perspective) mode in descendant cameras.

Each camera installed in an engine must inherit from either FrustumCam or OrthoCam.

Method Summary
	`frustum(self, left, right, bottom, top, near, far)` Sets frustum shape members.
	`perspective(self, fovy, aspect, near, far)` Alternate way to specify frustum.

Inherited from OrthoCam
	`ortho(self, left, right, bottom, top, near, far)` Sets frustum shape members.
	`shape(self, left, right, bottom, top, near, far)` Sets frustum shape members.
	`viewMV(self)` Sets eye and center position in OpenGL

Method Details

frustum(self, left, right, bottom, top, near=None, far=None)

Sets frustum shape members. (left, top, near) and (right, bottom, near) map to the diametrical opposite corners of the viewport, in x,y,z coords, modelview space.

near and far params are optional, and if ommitted, prior attribute values remain. all params are floats.

perspective(self, fovy, aspect, near, far)

Alternate way to specify frustum.

Parameters:: fovy - field of view angle, degrees; aspect - height/width (float); near - near side of viewing box (float); far - far side of viewing box (float)

viewProj(self)

Pushes frustum params/settings through to OpenGL

Overrides:: spyre.spyre.OrthoCam.viewProj
