Navigation functions

CAVENavLoadIdentity (void)
CAVENavTranslate (float x, float y, float z)
CAVENavRot (float angle, char axis)
CAVENavScale (float xscale, float yscale, float zscale)
Operate on the current navigation matrix. These functions are similar to the corresponding GL functions.
The transformations are in physical CAVE coordinates (they are post-multiplied).

CAVENavWorldTranslate (float x, float y, float z)
CAVENavWorldRot (float angle, char axis)
CAVENavWorldScale (float xscale, float yscale, float zscale)
Operate on the navigation matrix, but are pre-multiplied. These transformations thus are in world coordinates, rather than local CAVE coordinates.

CAVENavTransform (void)
Applies the latest navigation transformation.

CAVENavConvertCAVEToWorld (float inposition[3], float outposition[3])
CAVENavConvertVectorCAVEToWorld (float invector[3], float outvector[3])
Converts a position or direction vector from physical CAVE coordinates to navigated world coordinates.

CAVENavConvertWorldToCAVE (float inposition[3], float outposition[3])
CAVENavConvertVectorWorldToCAVE (float invector[3], float outvector[3])
Converts a position or direction vector from navigated coordinates to physical coordinates.

The tracking functions CAVEGetPosition(), CAVEGetOrientation(), and CAVEGetVector() can also return values in navigated, rather than tracker, coordinates. To do this, append _NAV to the name of the value being requested.
For example:

	CAVEGetPosition(CAVE_HEAD_NAV, headpos);
