Question

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解决方案允许我在给定一组顶点和三角形的情况下计算投影，而无需绘制3D网格

谢谢

您可以使用view命令旋转轴并更改视点。方位角和仰角以度为单位（有关更多信息，请参阅文档）。下面是一个小示例：

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])

Projections on different 2D planes

X-Z

Y-Z

X-Y
