Solid-clip methodology and architecture for clipping solid models and displaying cross-sections using depth-buffers |
摘要 |
A method, and apparatus for practicing the method, processes pixels to display a cross-sectioned image of a solid object. The method includes the steps of, for each pixel that projects onto the solid object, (a) determining, as a function of a depth of a clipping plane at a pixel, a parity of the pixel; and (b) for each pixel determined to have a predetermined type of parity, displaying the pixel with a visual characteristic selected to indicate that the pixel is a pixel that projects onto material that is within an interior of the solid object.
