METHOD AND DEVICE FOR GRAPHIC PROCESSING

摘要

PURPOSE: To provide a means and device for visualization which automatically generate an optimum light source information and sight information for a graphic model so as to surely visualize a three-dimensional graphic model for a graphic model that is insufficient in light source information and sight information as to three-dimensional graphic processing of CAD. CONSTITUTION: After two-dimensional coordinate transformation by a rendering module 20, a dark part judging routine 6 for luminance of a display analyzes dark parts of the three-dimensional model and a dark part gravity center position determination routine 7 groups the extracted dark parts and determines their center of gravity. And, a light source setting module 9 sets light source information for visualization for the gravity center position of the dark parts found by the dark part gravity center position determination routine 7 so as to draw the model.
