Abstract
A method for forming an image of an object on a display of a computer includes representing at least a portion of the object with a first strip of polygons that is described by a first set of points of a first coordinate space. One or more polygons of the first strip that will be invisible in the image are selected, and these polygons are culled from the first strip to form a second strip of polygons. The second strip of polygons is described by a second set of points of the first coordinate space. The culling is performed before the points of the second set are transformed into another coordinate space that is associated with the image.

A method for forming an image of an object on a display of a computer system, comprising:
- representing at least a portion of the object with a first strip of polygons described by a first set of points of a first coordinate space;
- selecting one or more polygons of the first strip that will be invisible in the image;
- and
- culling said one or more polygons from the first strip to form a second strip of polygons described by a second set of points of the first coordinate space, the culling being performed before the points of the second set are transformed into another coordinate space associated with the image and the culling comprising:
- padding the first set of points with redundant points to form the second set of points.
An article comprising a storage medium readable by a processor-based system, the storage medium storing instructions to cause a processor to:
- represent at least a portion of an object with a first strip of polygons described by a first set of points of a first coordinate space,
- select one or more polygons of the first strip that will be invisible in an image of the object to be formed on a display of the system,
- cull said one or more polygons from the first strip to form a second strip of polygons described by a second set of points of the first coordinate space before the points of the second set are transformed into another coordinate space associated with the image, and
- pad the first set of points with redundant points to form the second set of points.
A computer system comprising:
- a display adapted to form an image of an object, and
- a processor adapted to:
- indicate a first strip of polygons in a first coordinate space to represent at least a portion of an object,
- select one or more polygons of the first strip that will be invisible in the image,
- cull said one or more polygons from the first strip to indicate a second strip of polygons described by a second set of points of the first coordinate space before the points of the second set are transformed into another coordinate space being associated with the image, and
- pad the first set of points with redundant points to form the second set of points.
