METHOD AND APPARATUS FOR CONTROLLING SPATIAL RESOLUTION IN A COMPUTER SYSTEM

摘要

A computer implemented method of producing output pixels for a graphics system includes the steps of receiving one or more input pixels from the graphics system; performing rendering operations on the one or more pixels, wherein the rendering including the steps of: selecting one or more pixels of interest the resolution of which are to be increased; defining a sampling grid or a sampling orientation; multi sampling the one or more pixels of interest having a first resolution and multiple sampling points; collecting information from each sampled point; storing information from each sampled point as a virtual pixel; defining one or more pixels the resolution of which are one of to remain the same as received from the graphics system or the resolution of which are to be reduced; and rendering pixels of interest in a higher resolution than the their first resolution by rendering each virtual pixel into a physical pixel in a displayable frame or offscreen buffer.

1. A computer implemented method of producing output pixels for a graphics system, the steps comprising:
receiving one or more input pixels from the graphics system; performing rendering operations on the one or more pixels, the rendering including the steps of: selecting one or more pixels of interest the resolution of which are to be increased; defining a sampling grid or a sampling orientation; multi sampling the one or more pixels of interest having a first resolution and multiple sampling points; collecting information from each sampled point; storing information from each sampled point as a virtual pixel; defining one or more pixels the resolution of which are one of to remain the same as received from the graphics system or the resolution of which are to be reduced; and, rendering pixels of interest in a higher resolution than the their first resolution by rendering each virtual pixel into a physical pixel in a displayable frame or offscreen buffer.
