AffineTransform

class tri3d.geometry.AffineTransform(mat)

Linear transformation defined by a matrix.

\(x \mapsto M \begin{bmatrix}x \\ 1\end{bmatrix}\)

Parameters:

mat (ndarray)

property single: bool

Whether this is a single transformation or a batch.

apply(x)

Apply transformation to given point or array of points.

The broadcasting rules between transformations and their inputs are as follows:

transform	input	output	brodcast
[]	[3]	[3]	single mapping
[]	[n,3]	[n,3]	broadcast transform
[n]	[3]	[n,3]	broadcst input
[n]	[n]	[n,3]	one-to-one mapping

Return type:

ndarray

inv()

Return inverse transformation.

Return type:

Self
