Animating sketches via kinetic textures

A non-transitory computer-readable medium storing program instructions that, when executed by a processing unit, cause the processing unit to generate an animation, by performing the steps of:

• generating a first sketch element within a sketch animation, wherein the sketch animation includes one or more static line drawings;
• generating an emitter element within the sketch animation, wherein the emitter element includes at least one line segment or point;
• causing the first sketch element to move from a first position within the sketch animation to a second position within the sketch animation, thereby causing the first sketch element to traverse a first portion of the sketch animation;
• and
• rendering the sketch animation for display on a display device as the first sketch element traverses the first portion of the sketch animation.

A system configured to generate an animation, comprising:

• a memory unit;
• a processing unit, coupled to the memory unit and configured to:
• generate a first sketch element within a sketch animation, wherein the sketch animation includes one or more static line drawings,
• generate an emitter element within the sketch animation, wherein the emitter element includes at least one line segment or point, and
• cause the first sketch element to move from a first position within the sketch animation to a second position within the sketch animation, thereby causing the first sketch element to traverse a first portion of the sketch animation, and
• render the sketch animation for display on a display device as the first sketch element traverses the first portion of the sketch animation.
