Each fragment processor fetches and adds values from input textures and stores the result of the addition in the target texture C.
To test our algorithms, we used an NVIDIA GeForce 7800 GTX (24 fragment processors, 580 MHz core clock cycle, 1750 MHz memory clock cycle, 512 MB GDDR3 memory, 256 bit bus) and an Intel Xeon 3.
To make the scenes realistic, texture mapping is performed by fragment processors, which color or shade the fragments using textures specified by a bitmap pattern.
