Design, 3d Graphics Components Based On Vxworks

With the import of the Embedded system, the behindhand development method of Embedded system is improved, the development speed is accelerated and expansibility is enhanced. Along with the development of the multi-media information technique, network and consumed electronics product, due to the low memory require, cutter ability and stability, Embedded system operation system is extensively used. Embedded equipment such as mobile telephone start to use the large quantity multi-media of the audio contents and video contents. Multi-media applications require the high image quality, which require high quality 3D draw function. Te meet this challenge, we should study how to make the application of 3D graphics algorithms with Embedded system.This thesis analyzed the structure level of the 3D graphics library, introduced the 3D graphics library function's function and the theory and algorithms needed to implement each function. Then refer to the transact flow of OpenGL, realized the 3D effect required module based on the VxWorks operation system's in existence 2D graphics development module WindML, which include all the functions to draw the basic geometry drawing(dot, line, polygon), cut out functions, matrix transform functions, color, illumination, texture, bitmap functions and so on. On the design process, we analyzed how to test the 3D algorithms. Be dead against Embedded system's requirement with storage and run memory, high reliability, portable and configure ability, we adopt some simple and high efficiency 3D algorithms to reduce storage and run memory. The 3D algorithms designed use C to develop, have a good portable, code is stable and reliable, and the it's interface is easy to use, Finally the thesis use the designed module to compile and run 3D test program on the VxWorks operation system, and test the 3D effect of the module.
