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.
