Q3Point_GetData

You can use the Q3Point_GetData function to get the data that defines a point object and its attributes.

TQ3Status Q3Point_GetData (
TQ3GeometryObject point, 
TQ3PointData *pointData);

point

A point.

pointData

On exit, a pointer to a TQ3PointData structure that contains information about the point specified by the point parameter.

DESCRIPTION

The Q3Point_GetData function returns, through the pointData parameter, information about the position and attribute set of the point specified by the point parameter. QuickDraw 3D allocates memory for the TQ3PointData structure internally; you must call Q3Point_EmptyData to dispose of that memory.
