Abstract: Input is received that selects an animation aspect associated with an object within an animation. The animation involves the object and an original frame of reference through which the animation is displayed, and the selected animation aspect is one that changes over time with respect to the original frame of reference. The animation is displayed through a new frame of reference defined by holding the selected animation aspect constant over time. During the animation display through the new frame of reference, input is received that manipulates the object to create a new animation aspect associated with the object. The new animation aspect associated with the object is recorded in the animation.

Abstract: Methods and apparatus, including computer program apparatus, implementing techniques for processing digital artwork. In one aspect, the techniques process aggregations of artwork where both the aggregation and at least some of the aggregated artwork have attached styles. The techniques handle various combinations of conditions resulting in applying style elements to the aggregation before or after applying style elements to underlying artwork. In another aspect, the techniques implement editable path objects having multiple attached fills and/or strokes. The techniques provide user interfaces for using the foregoing features.

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.

Abstract: A method of producing a frame sequence file from a two-dimensional virtual canvas includes receiving control instructions from a user and thereafter, producing frame sequence file frames by repeatedly mapping a virtual camera frame upon the virtual canvas in accordance with the control instructions, processing virtual canvas information within the mapped virtual camera frame in accordance with the control instructions, and saving the processed virtual canvas information as one frame in the frame sequence file. Additionally, the canvas artwork may be animated during frame sequence file generation.
