  • Patent number: 4663616
    Abstract: A technique is provided the user of an interactive computer graphics application which allows the user to attach lines to objects such that when the objects move, the lines will rubber-band to follow the object. The objects are provided with an attribute that describes their "stickiness". If an object is given the "sticky" attribute, then lines which touch or overlay the object will rubber-band to follow the object's movement. It is also possible to provide end points of lines with the "sticky" attribute so that the end points of lines can be attached to objects. Further, objects of arbitrary geometric shape can be attached to other objects of arbitrary geometric shape using the "sticky" attribute. The feature facilitates editing and revision of graphic files.
