For Mobile Devices Of Realistic Graphics Processing Algorithms

In recent years, graphical display technology is composed of 2D plane model shows that the transition to 3D graphics, 3D technology has been widely applied in animation, online games, city planning etc.. Photorealistic rendering refers to in the real world scene on the computer display. In the real world objects with shape features,optical properties, surface texture and different degree of difference, and the relative position between things and things inherent characteristics of occlusion.There are several problems in the design of mobile device oriented realistic graphics processing system: first, realistic graphics rendering needs faster speed; second,realistic graphics rendering can not have too high power consumption; third, rendering techniques can be applied to all types of mobile devices. This paper analyzes the present situation of the domestic and foreign realistic graphics rendering technology, puts forward the rendering needs to be based on the "realistic" and "moving" characteristics,from the design of realistic graphics processing system for mobile devices from the modeling of.In this paper, in-depth study based on realistic 3D graphics processor to mobile devices are in decline, the speed increase, the chip power consumption and increasing the flexibility as the goal, design a realistic graphics 3D graphics processor with low complexity, low power consumption, high performance of the algorithm, using the algorithm to enhance the speed of the hardware implementation, the mobile device can draw graphics computing power required by the user.In this paper, the algorithm of realistic graphics rendering is a serious discussion,the key algorithms including coordinate geometry phase transformation, illumination,clipping, scan algorithm, grating phase screen anti aliasing algorithm, texture mapping algorithm and hidden surface algorithm. Optimization strategies include the following:cutting operation to reduce the amount of storage space, number of visits, the purpose is to realize the operation speed, reduce the chip area and power consumption of the chip to reduce the.In order to verify the algorithm successfully, this study also uses C language simulation and verification are completed. According to the OpenGL ES interface, to achieve the function key is to write all the geometry and not part of the grating.Compare the simulation optimization algorithm in after rendering and volume rendering OpenGL. To verify whether the algorithm to realize the optimization of the real meaning of the.
