Abstract
A hybrid rendering method includes subdividing a two-dimensional (2D) frame into virtual tiles (hereinafter, referred to as ‘tiles’); classifying the tiles into first tiles which include an object having reflective or transparent properties and second tiles which do not include the object having reflective or transparent properties; storing geometric information of a primitive in the first tiles in a graphics processing unit (GPU) internal memory; and generating a first image by rendering one or more of the first tiles via ray tracing using the geometric information, generating a second image by rendering one or more of the second tiles via rasterization, and outputting a final image by merging the first and second images.
