如何计算预测的3D网格在MATLAB [英] How to compute projections of 3D meshes in matlab

问题描述

我试图来计算使用MATLAB不同意见的3D网格的2D投影。 我米用现在的解决办法，是绘制三维网格，旋转，并进行了截图。

I'm trying to compute 2d projections of a 3d mesh from different views using matlab. The solution I m using now, is to plot the 3d mesh, rotate it, and make a screenshot.

我想知道是否有任何MATLAB内部函数或任何其他的解决方案，让我，给定一组顶点和三角形的，计算的预测，而无需绘制三维网格

I would like to know if there is any matlab internal functions or any other solution that allow me, given a set of vertices and triangles, to compute the projections without having to plot the 3D mesh

感谢

推荐答案

您可以使用的 视图 命令，旋转轴和改变观点。方位角和仰角以度给出（参见更多信息文档）。这里有一个小例子：

You can use the view command to rotate the axes and change the viewpoint. The azimuth and elevation are given in degrees (ref. documentation for more info). Here's a small example:

ha=axes;
[x,y,z]=peaks;
surf(x,y,z);
xlabel('x');ylabel('y');zlabel('z')

%#projection on the X-Z plane
view(ha,[0,0])

%#projection on the Y-Z plane
view(ha,[90,0])

%#projection on the X-Y plane
view(ha,[0,90])

这是什么样子的：
