Q3GeneralPolygon_GetData

You can use the Q3GeneralPolygon_GetData function to get the data that defines a general polygon and its attributes.

TQ3Status Q3GeneralPolygon_GetData (
TQ3GeometryObject generalPolygon, 
TQ3GeneralPolygonData *generalPolygonData);

generalPolygon

A general polygon.

generalPolygonData

On exit, a pointer to a TQ3GeneralPolygonData structure that contains information about the general polygon specified by the generalPolygon parameter.

DESCRIPTION

The Q3GeneralPolygon_GetData function returns, through the generalPolygonData parameter, information about the general polygon specified by the generalPolygon parameter. QuickDraw 3D allocates memory for the TQ3GeneralPolygonData structure internally; you must call Q3GeneralPolygon_EmptyData to dispose of that memory.
