Q3TriGrid_GetData

You can use the Q3TriGrid_GetData function to get the data that defines a trigrid and its attributes.

TQ3Status Q3TriGrid_GetData (
TQ3GeometryObject trigrid, 
TQ3TriGridData *triGridData);

trigrid

A trigrid.

triGridData

On exit, a pointer to a TQ3TriGridData structure that contains information about the trigrid specified by the trigrid parameter.

DESCRIPTION

The Q3TriGrid_GetData function returns, through the triGridData parameter, information about the trigrid specified by the trigrid parameter. QuickDraw 3D allocates memory for the TQ3TriGridData structure internally; you must call Q3TriGrid_EmptyData to dispose of that memory.
