How to disable perspective in mplot3d?

matplotlib, mplot3d, python

Solution

NOTE: This has been updated see this answer instead.

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

It is currently an open issue found here.

Problem

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