网格简化程序基于3D三角网格简化，代码简单实用，而且非常有效的节省时间(meshsimplification is a C++ library and set of utilities for input, output, and basic manipulation of 3D triangle meshes. The goals of the code are ease of use and efficiency, possibly at the expense of some generality.)

unreal engine 4的虚拟现实模板，用UE4.5版本实现，并供大家参考，且亲测可以使用，无密码。(Engine unreal 4 virtual reality template, with the UE4.5 version to achieve, and for your reference, and pro test can be used, no password.)

说明：  一个widget内分开处理两个actor(one widget handle two saperate actor)

计算点云数据的法向量和局部特征,以备三维重建运用(The normals and features can be computed from a point cloud using the NormFet software)

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.)

三维点云的伪彩色显示示例。自带5片点云用于测试。可平移、旋转、缩放视图；可单色、伪彩色显示点云。(An example of pseudo-color display of three-dimensional point clouds. It has five point clouds for testing. It can translate, rotate and zoom views; it can display point clouds in monochrome and pseudo-color.)

这是用open cascade来实现绘制简单的B样条曲线和样条曲面的程序。可以用来对open cascade的入门学习。(This is used to achieve open cascade easy mapping of B-spline curves and spline surfaces procedures. Can be used to open cascade of study entry.)
