The main contents of this research are the following : ( 1 ) the technology of graphic and image - based modeling and rendering is adopted , and 3d model of virtual campus system were accomplished . the geometry modeling of complex object is explored in vr , and commonly means were summed up such as trees , flower and grass etc . this paper also analyzed texture mapping problems of big and small geometry object , which can reduce workload of building scene ( 1 )采用图形与图像混合建模技术,实现了vcs虚拟校园系统的三维建模,并对虚拟世界中复杂物体建模技术进行了探索,总结出了树木、花草等复杂对象建模的一般方法,分析并解决了几何体的纹理映射问题,极大地减少了场景制作的工作量。
It proves that the improved bp network model solves the nonlinear mapping problem of the color space transformation . the model will have certain significance to the further study of color management , and the corresponding screen color calibrator will have certain meaning and applied value 改进之后的算法很好地解决了色空间转换中的非线性问题,对今后色彩管理的深入研究具有一定的理论意义;利用这一算法研制的计算机屏幕色彩校准器具有重要的理论意义和实际应用价值。
Computing brain resistivity parameters by using the wavelet neural network method the eit inverse resolution is a non - linear mapping problem . here it is presented that the brain resistivity parameters is computed by using the wavelet neural network method . not only can it resolve non - linear mapping problem , but also overcome the shortage of non - convergence and expending long cpu time in other reconstruction algorisms 提出并实现了用小波神经网络求解脑内电参数提出应用小波神经网络求解脑内组织的电导率参数,构造了用于脑电eit问题的小波框架,并用于脑电参数的求解,较好地解决于阻抗成像的非线性映射问题,避免了其他重构算法中迭代优化收敛差、耗时长的缺点。
