Claim One:
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, wherein the classifying of the tiles comprises: extracting properties of primitives in the tiles; and determining, among the tiles, a tile including a primitive having one of a reflectivity and a refractive index greater than 0 as the first tile, by using the extracted properties of the primitives, wherein the extracting of the properties of the primitives in the tiles comprises: performing binning to determine a tile in which each of the primitives is included from among the tiles; generating information about mapping between the respective tiles and the primitives; and acquiring list of the primitives in each of the tiles by using the mapping information, to extract properties of the primitives in the list of primitives.
