Abstract: In a computer graphics modeling system, a method for accurately positioning a cursor on a geometric point of a three dimensional object (such as an object vertex) shown in a two dimensional projected view. The system monitors the position of a movable pointer on a two dimensional projected view of the three dimensional object. When the user desires to accurately position the cursor on the object, the user signals the system via an input device or other means. The system receives the signal, which indicates that the pointer is preliminarily aligned with a geometric point on the object. In response to the signal, the system determines the position of a nearest geometric point to the pointer and moves the pointer to the spatial coordinates of the point's position. To aid in identifying geometric points, they are visibly different in the projected view from non-geometric points.

Abstract: A golf putter head having a polyurethane body with a face, toe and heel, and having weighting material connected to toe and heel. The weighting material is inserted in chambers sealed with a plug, or alternatively is molded into the polyurethane body. The weighting material does not project through the putter face, giving a larger sweet spot and softer feel to the putter.
