用于点云切片功能的实现，非常好用，可以计算密度、厚度、等内容(For point cloud slicing feature to achieve very easy to use, you can calculate the density, thickness, etc.)

三维图形的切割就是要把三维网格模型进行切割然后以等值线显示切面上的数值。运用适当的三维图形显示技术和可视化C++编成技术来实现的。(Three-dimensional graphics of the cut is to take three-dimensional grid model and then cut the contour values on the display section. Use of appropriate three-dimensional graphics display technology and visualization techniques to compiled C++ implementation.)

说明：  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.)

该程序为立体空间内艾里光束的传播，使用角谱传播定理(The program for the Airy beam propagation in three-dimensional space, using the angular spectrum propagation theorem)

本程序是基于平面图对建筑规模场景进行三维重建。(This procedure is based on the floor plan for the construction scale of the three-dimensional reconstruction of the scene.)

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.)

实现对函数的步长加速法寻优，并作图直观显示寻优过程和效果(The step function to achieve acceleration method optimization and mapping visual display optimization process and effects)

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