Q3Polygon_GetData

You can use the Q3Polygon_GetData function to get the data that defines a simple polygon and its attributes.

TQ3Status Q3Polygon_GetData (
TQ3GeometryObject polygon, 
TQ3PolygonData *polygonData);

polygon

A simple polygon.

polygonData

On exit, a pointer to a TQ3PolygonData structure that contains information about the simple polygon specified by the polygon parameter.

DESCRIPTION

The Q3Polygon_GetData function returns, through the polygonData parameter, information about the simple polygon specified by the polygon parameter. QuickDraw 3D allocates memory for the TQ3PolygonData structure internally; you must call Q3Polygon_EmptyData to dispose of that memory.
