Abstract
The present invention allows for rendering, with a micropolygon renderer, motion blurred images of objects modeled and animated with the most commonly used class of implicit surfaces. The invention introduces the technique of automatic implicit differentiation to automatically compute the time derivatives of points on the combined surface from the time derivatives of the constituent surface elements while evaluating the combined field function that defines the composite surface.
