METHOD AND APPARATUS FOR RENDERING 3 DIMENSIONAL GRAPHICS DATA CONSIDERING FOG EFFECT

摘要

A method and an apparatus for rendering 3D(Dimensional) graphics data in consideration of fog effects are provided to reduce the number of memory accesses for reading textures by performing the texture mapping according to strength of the fog effects which will be applied to the 3D graphics data, and reduce time for the memory access. A rendering method comprises the following steps of: calculating strength of fog effects which will be applied to graphics data; determining whether to perform texture mapping for each of pixels or vertexes of a polygon as a configuration unit of at least one or more objects, indicated by the graphics data, according to the calculated fog effects(106); and performing the texture mapping according to the determination result(107).
