METHOD AND APPARUTUS FOR SELECTIVE TESSELATION

摘要

Provided are a method and an apparatus for selectively tessellating by using a two-pass rendering pipeline. Disclosed is the method for selectively tessellating which comprises the following steps: generating a domain visible stream representing whether at least one domain of an input patch is visible or not when the domain is rendered; generating domain information on a visible area of the input patch by using the domain visible stream; and performing domain shading on the visible domain based on the domain information.
