Apparatus and method for direct calculation of clip region outcodes. |
摘要 |
<p>An apparatus and method for calculating outcodes directly from an integral representation of a floating point number defining a certain coordinate of a point of an object to be displayed. Such calculations under software control are absent any Boolean conventional branch instructions which impede system performance and utilize an integer unit rather than a floating point unit so as to enable transformations of viewing parameters and calculations of outcodes to be performed in a concurrent manner.</p> |
