摘　　要：以二次曲面的等灰度实时成像算法为基础，研究了以二次曲面为图元拼接曲面物体的两类情况。第一次提出了适合于大多数情况的二次曲面图元拼接形体的实时成像方法，该方法简洁、高效，完全能满足实时要求。Based on the equi-intensity principle on real-time imaging, the paper is devoted to a research on two classes of piecing together solid objects with typical quadric surfaces, advancing for the time an effective method of its kind applicable in most cases. In addition, the paper verifies the algorithms mentioned above by generating an aeroplane shading in the C language in computer.
