Geometric Object Types

Every QuickDraw 3D geometric object has an object type, which you can determine by calling the Q3Geometry_GetType function. Q3Geometry_GetType returns one of the following constants, or kQ3ObjectTypeInvalid if the type of an object cannot be determined or is invalid.

#define kQ3GeometryTypeBox              Q3_OBJECT_TYPE('b','o','x',' ')
#define kQ3GeometryTypeCone             Q3_OBJECT_TYPE('c','o','n','e')
