Detailed Description

The range of visible frustum of an orthographic camera is determined by the extent of film plane in world space.

Constructor & Destructor Documentation

inline

In addition to camera position and orientation, an orthogonal camera specifies width and height of the film plane directly.

Parameters

position	Position.
focus	Focus.
up	Rough up direction.
xextent	Width of the frustum in world space.
yextent	Height of the frustum in world space.
tnear	Near clip plane.
tfar	Far clip plane.
