Reseach And Implement On Three-dimensional Effect Synthesis Based On Textured Material

With the rapid development of computer graphics technology in recent years, there has been a rapidly increasing in computer hardware performance, people’ requirements for realistic visual effects are also getting higher and higher. In fields such as games and movies, photorealistic rendering effects are becoming increasingly important. To keep up with the progress of the times, to meet the people’s growing demand, research for new graphics algorithm thus also become increasingly important.Synthesis of three-dimensional effects has been a hot topic in the field of computer graphics. In the past, the synthesis of three-dimensional effects, mostly synthetic approach used is based on three-dimensional modeling, the advantage lies in the synthesis of realistic effect is strong, but the disadvantage is equally obvious that the calculation is too big. The textures based rendering technology, which has result not inferior to the realistic modeling of three-dimensional rendering of too many cases, greatly reducing the amount of computation rendering process, which greatly improved the rendering speed. For this advantage, the three-dimensional effects synthesis technology based on texture, improved conventional synthetic techniques to make it more adapted to modern society graphics technology requirements.This thesis describes and researches some advanced computer graphics technology such as the synthesis based on feature profile and relief map, and history of the development of related technologies. In the implementation process, the paper first processed the input grayscale with extraction algorithm(PPA), and then realized the image synthesis feature based on feature profile. Next, the paper realized the transition from grayscale to a normal map. In the end, through the use of relief mapping technology, this paper achieves a realistic simulation of the three-dimensional effects synthesis. This paper studied the previous advanced theory, combined three-dimensional effects synthesis with texture technology innovatively, in the case without damaging the realistic effects to enhance the overall rendering speed.
