Constructor & Destructor Documentation

vtHUD::vtHUD (  bool  bPixelCoords = true  )

Create a HUD node. A HUD ("heads-up display") is a group whose whose children are transformed to be drawn in window coordinates, rather than world coordinates. You should only ever create one HUD node in your scenegraph. Parameters: bPixelCoords  If true, the child transforms should be interpreted as pixel coordinates, from (0,0) in the lower-left of the viewpoint. Otherwise, they are considered in normalized window coordinates, from (0,0) in the lower-left to (1,1) in the upper right.

Member Function Documentation

void vtHUD::Release (   )  [virtual]

Releases a node. Use this method instead of C++'s delete operator when you are done with a node. Internally, the node is reference counted so it is not deleted until all references to it are removed. Reimplemented from vtGroup.
