ABSTRACT:
A method for drawing a surface model performs modelling for plural primitive surface models, each primitive surface model being a part of the surface model, and applies drawing priority to each primitive surface model. Then, the method draws the primitive surface model with hidden surface removal based on depth values when the primitive surface model has the same drawing priority as the drawing priority of another primitive surface model, and draws the primitive surface model without hidden surface removal when the primitive surface model has a higher drawing priority.
