h2e

marxs.math.utils.h2e(h)

Convert homogeneous coordinates to Euclidean coordinates

This functions works for points at infinity and for points in real euclidean space, but it expects that each time it is called h contains only the one or the other but not a mixture of both.

Parameters

hnp.array

Input homogeneous coordinates. This can be multidimensional, but the last dimension must be of size 4.

Returns

enp.array

Euclidean coordinates. Same shape as e except that the last last dimension is now has 3 elements.
