研究了文物剖视图和等值线图绘制方法,提出了基于剖切平面的文物剖视图和等 值线图的快速绘制方法,该方法有效利用剖面轮廓线的连续性,提高了绘制速度。实验结果证明线条流畅,绘图结果准确

This program implements four different mesh simplification algorithms. After loading a mesh, the user can easily remove triangles from the mesh and the results are displayed in real time. The mesh can also be rotated and moved closer to or farther away from the viewer. The goal of mesh simplification is to display a 3D polygonal mesh with fewer triangles while retaining the same shape. In the example above, the original cow model (upper left) is made up of over 5800 triangles. We can easily remove thousands of triangles from this mesh and still display a very similar cow model. While the 500 triangle cow is a cruder representation, this may not make a difference if the cow is far away from the viewer.

设计一个类似于windows附件中绘图板的程序 ，画直线状态下点鼠标左键位置为直线的起点，松开鼠标所在位置点为终点。 画圆状态下圆心，松开鼠标所在位置点为圆上一点。
