如何在mplot3d中禁用透视图? [英] How to disable perspective in mplot3d?

问题描述

在mplot3d中进行绘制时是否可以禁用透视图，即使用正交投影?

Is it possible to disable the perspective when plotting in mplot3d, i.e. to use the orthogonal projection?

推荐答案

排序，可以在绘制之前运行以下代码段:

Sort of, you can run this snippet of code before you plot:

import numpy
from mpl_toolkits.mplot3d import proj3d
def orthogonal_proj(zfront, zback):
    a = (zfront+zback)/(zfront-zback)
    b = -2*(zfront*zback)/(zfront-zback)
    return numpy.array([[1,0,0,0],
                        [0,1,0,0],
                        [0,0,a,b],
                        [0,0,0,zback]])
proj3d.persp_transformation = orthogonal_proj
