void vdsSetThreshold (vdsFloat thresh)

Set the simplification threshold for the standard simplification callback

Set the simplification threshold for the standard simplification callback. This threshold corresponds to a fraction of the angular field of view (as specified by vdsSetFOV). The standard simplification callback directs nodes whose on-screen extent exceeds this fraction to be unfolded, while nodes smaller on screen than the threshold are folded.

Parameters:

thresh - the fraction of the angular field-of-view below which nodes should be folded.
