= 2,	Parallel view defined (gDefineParallelView())

vstate.cflag
View centre flag

= 0,	No view centre defined

= 1,	Default view centre defined

= 2,	User defined view centre (gPosViewCentre())

vstate.upflag
View up direction flag

= 0,	Default view up vector (0.0,1.0,0.0)

= 1,	User defined view up vector (gSetViewUpDirection())

vstate.dir

Description

The routines gSetViewParams() and gSetViewState() set the viewing parameters to the values stored in the appropriate structure. The current settings are obtained through the routines gGetViewParams() or gGetViewState(). The new settings may subsequently be modified by using one of the viewing routines but are only activated after updating the current view using gUpdateView().
