Computer Plotting of Quadric Surface
Quadric surface is an important part of complex object and free form object, showing its graphics is hot research of computer graphics and 3D data visualization. Researching quadric and deducing the process of its classification. Taking three 3D graphics commands contour3,ezmesh and ezsurf as main line, it is analyzed that 3D drawing function of Matlab7.It comes true that programming is to draw 3D graphics of all kinds of quadric, and it was compared that various graphics results, it can provide reference for computer mapping of any other surface objects.
