Hit Path Structure

You use a hit path structure to get group information about the path through a model hierarchy to a specific picked object. A hit path structure is defined by the TQ3HitPath data type.



 
typedef struct TQ3HitPath {

    TQ3GroupObject                      rootGroup;

    unsigned long                       depth;

    TQ3GroupPosition                    *positions;

} TQ3HitPath;

rootGroup: The root group that was picked.
depth: The number of positions in the path. If the picked object is not in the model hierarchy, this field contains the value 0.
positions: A pointer to an array of group positions. This array is allocated by QuickDraw 3D.
