一个VRML的示例，通过鼠标点击可以使场景内的灯管发光(An example of a VRML through mouse clicks can make a scene inside the lamp light)

欧洲winner2的官方3D天线信道模型源程序 内包含十多种场景选择 考虑了角度扩展 k参数等(H=WIM(WIMPAR,LINKPAR,ANTPAR) is a 5D-array of channel coefficients. For explanation of the input parameter structs, see WIMPARSET, LAYOUT2LINK, LAYOUTPARSET, and ANTPARSET. H is a cell array of size K (number of links.SIZE(H{i})=[U S N T], where U is the number of MS (RX)elements, S is the number of BS (TX) elements, N is the number of paths,T is the number of time sample)

说明：  课程设计的主要内容为开发一个实时绘制大规模三维场景的程序系统.必做部分： 1、学习3DS Max 的基本功能，并采用3DS Max 对三维场景进行建模，要求 场景中包含建筑物、道路、天空等基本元素，实现场景的纹理贴图功能。 2、通过3DS Loader 读取场景数据。。 3、学习并使用OpenGL 或DirectX 3D 实时绘制上述场景。 4、提供用户界面，并实现场景的交互漫游功能。 选做部分： 1、在场景中添加了三维地形。 2、实现雾这种气象条件的实时绘制。 3、实现计算机动画技术，飞机在天空中飞，圆环在不停的运转。 4、阴影的绘制 5、在场景中添加了喷泉。 6、实现Billboard 绘制技术。 7、添加了美妙的背景音乐。 (The main content of curriculum design for the development of a real-time rendering system of procedures for large-scale three-dimensional scene (running Interface, refer to Figure 1), including part and the election will be made part (where part of the requirements to achieve Optional 2 to 3 Or more than function). Will be part of: 1, learning the basic functions of 3DS Max, and three-dimensional scene using 3DS Max for modeling, requirements Scene includes buildings, roads, skies and other basic elements, to achieve the texture mapping function of the scene. 2, read the scene data by 3DS Loader. . 3, learn and use OpenGL or DirectX 3D real-time rendering the scene. 4, provide the user interface and interaction to achieve the scene roaming. Optional parts: 1, in the three-dimensional terrain scenes added. 2, the fog that weather conditions to achieve real-time rendering. 3, the realization of computer animation technology, aircraft flying in the sky, circle in)
