Abstract
An approach is described for using hardware devices to generate modified geometry objects based on instructions provided by extension objects. An extension object is associated with a sequence of components, such as a modifier stack, that are used to modify a geometry object to generate an initial representation of the geometry object. Instructions that are based on the extension object are associated with the initial representation. A graphics device, such as a hardware shader, is used to generate a final representation of the geometry object based on the instructions and the initial representation. The instructions may be executed by an application program interface to provide instructions to the graphics device for generating the final representation of the geometry object. The instructions may be generated based on the extension object, and a graphics card may execute the instructions to generate the final representation of the geometry object.
