Abstract
Techniques for anti-aliasing for geometries are described. In at least some embodiments, a graphical image is reduced to a collection of polygonal geometric primitives (“geometries”). The individual geometries are processed according to techniques discussed herein such that anti-aliasing is applied to the geometries when the geometries are displayed as part of the graphical image. For example, anti-aliasing of a general-purpose geometry is achieved via an associated collection of quadrilaterals and bevels that can be dynamically transformed when the geometry is rendered for display. In at least some embodiments, quadrilaterals and bevels generated for a geometry enable the geometry to be dynamically transformed and re-rendered multiple times to achieve a variety of visuals.
