@see viewingSpace.

view4dToWorld(input: Point4d, out?: Point3d): Point3d Convert a point from CoordSystem.View as a Point4d to CoordSystem.View  
view4dToWorldArray(viewPts: Point4d[], worldPts: Point3d[]): void Convert an array of points from CoordSystem.View as Point4ds to CoordSystem.World  
viewToNpc(pt: Point3d, out?: Point3d): Point3d Convert a point from CoordSystem.View to CoordSystem.Npc  
viewToNpcArray(pts: Point3d[]): void Convert an array of points from CoordSystem.View to CoordSystem.Npc  
viewToWorld(input: Readonly<WritableXYAndZ>, out?: Point3d): Point3d Convert a point from CoordSystem.View to CoordSystem.World  
viewToWorldArray(pts: Point3d[]): void Convert an array of points from CoordSystem.View to CoordSystem.World

worldToNpcArray(pts: Point3d[]): void Convert an array of points from CoordSystem.World to CoordSystem.Npc  
worldToView(input: Readonly<WritableXYAndZ>, out?: Point3d): Point3d Convert a point from CoordSystem.World to CoordSystem.View  
worldToView4d(input: Readonly<WritableXYAndZ>, out?: Point4d): Point4d Convert a point from CoordSystem.World to CoordSystem.View as Point4d  
worldToView4dArray(worldPts: Point3d[], viewPts: Point4d[]): void Convert an array of points from CoordSystem.World to CoordSystem.View, as Point4ds  
worldToViewArray(pts: Point3d[]): void Convert an array of points from CoordSystem.World to CoordSystem.View  
createFromViewport(vp: Viewport): undefined | ViewingSpace Static Create from a Viewport.
