SHADING 3-DIMENSIONAL COMPUTER GENERATED IMAGES |
摘要 |
A method and apparatus for shading 3-dimensional computer generated images represents each object in the image as a set of polygons. An image plane on which the image is to be displayed is divided into a plurality of rectangular areas. Data defining the location of each polygon is then supplied. The rectangular areas which are required to show the whole of the polygon are then determined. Then, for each pixel in each rectangular area, the depth value is determined for the distance of a surface of the polygon from the image plane and a determination is made as to whether or not the surface is visible at that pixel. The pixel is shaded on dependence on the result of this determination. |
