Abstract
A method and apparatus for defining a smooth shading across an object for display on a raster output device. The method including converting the object to a mesh, rendering the mesh displaying the object having a shading defined by the mesh and editing the mesh until a desired result is achieved in the displayed object. The method may include a method for defining a gradient across an object for display on a raster output device where the object includes a boundary comprising multisegment edges in which the method includes selecting the object and finding the boundary for the object. Thereafter a bounding box is created including four corners that encloses the object boundary. Four points on the boundary of the object are identified that are closest to the four corners of the boundary box. A single patch mesh may be constructed from the four points and segments connecting pairs of the four points. The single patch mesh may be further divided to create a series of patches defining the gradient where patch boundaries correspond to segment vertices in the multisegment edges of the boundary of the object.
