An Invitation to 3d vision 一书的配套源代码，对3d视觉和3d重建感兴趣的可以看看(Source code accompany <An Invitation to 3d vision >, anyone who is interested in 3d vision and reconstruction should see this.)

说明：  大规模地形渲染, 大规模地形渲染, (terra render)

VTK里面的对点云进行降采样的程序，可以直接使用。(VTK point cloud inside the down-sampling procedure can be used directly.)

说明：  三维重建是指对三维物体建立适合计算机表示和处理的数学模型,是在计算机环境下对其进行处理、操作和分析其性质的基础,也是在计算机中建立表达客观世界的虚拟现实的关键技术。(Three-dimensional reconstruction refers to the establishment of a mathematical model suitable for computer representation and processing of three-dimensional objects. It is the basis for processing, manipulating and analyzing their properties in the computer environment. It is also the key technology for establishing a virtual reality to express the objective world in the computer.)
