1. A hybrid rendering method comprising: subdividing a two-dimensional (2D) frame into tiles; classifying the tiles into first tiles comprising an object having reflective or transparent properties and second tiles lacking the object having the 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 of the primitive of the first tiles, 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.
