Introduction

This gem presents an extension to image refinement algorithms by incorporating adaptive refinement: an image based on priority.

The generation of pixel values, whether by an abstract process (rendering) or by empirical sampling (scanning), is a sequential process. For interactive purposes, this does not provide the user a “thumbnail” preview of the entire image. Fast production of reduced-quality image is of value both in previewing systems and in production of frames whose objects show rapid, dynamic changes.

A previous gem (Hollasch 1992) addresses the issue of providing an overall ...
