Projection

class compas.geometry.Projection

Bases: Transformation

Class representing a projection transformation.

Parameters:

matrixlist[list[float]], optional

A 4x4 matrix (or similar) representing a projection transformation.

checkbool, optional

If True, the provided matrix will be checked for validity.

namestr, optional

The name of the transformation.

Raises:

ValueError

If check is True and the provided transformation matrix is not a projection matrix.

Methods

from_entries	Constructs a perspective transformation by the perspective entries of a matrix.
from_plane	Construct an orthogonal projection transformation to project onto a plane.
