angle_points
- compas.geometry.angle_points(a, b, c, deg=False)[source]
Compute the smallest angle between the vectors defined by three points.
- Parameters:
- a[float, float, float] |
compas.geometry.Point XYZ coordinates.
- b[float, float, float] |
compas.geometry.Point XYZ coordinates.
- c[float, float, float] |
compas.geometry.Point XYZ coordinates.
- degbool, optional
If True, returns the angle in degrees.
- a[float, float, float] |
- Returns:
- float
The smallest angle in radians (in degrees if
deg == True). The angle is always positive.
Notes
The vectors are defined in the following way
\[\begin{split}\mathbf{u} = \mathbf{b} - \mathbf{a} \\ \mathbf{v} = \mathbf{c} - \mathbf{a}\end{split}\]Z components may be provided, but are simply ignored.
