# project_point_plane

compas.geometry.project_point_plane(point, plane)[source]

Project a point onto a plane.

Parameters
Returns

[float, float, float] – XYZ coordinates of the projected point.

Notes

The projection is in the direction perpendicular to the plane. The projected point is thus the closest point on the plane to the original point 1.

Examples

>>> from compas.geometry import project_point_plane
>>> point = [3.0, 3.0, 3.0]
>>> plane = ([0.0, 0.0, 0.0], [0.0, 0.0, 1.0])  # the XY plane
>>> project_point_plane(point, plane)
[3.0, 3.0, 0.0]
