Origin
(point, xaxis, yaxis)[source] Bases:
compas.geometry.primitives.frame.Frame
Reference frame represented by an instance of
Frame
.An origin is defined by a base point and two orthonormal base vectors.
- Parameters
point (point) – The origin of the origin.
xaxis (vector) – The x-axis of the origin.
yaxis (vector) – The y-axis of the origin.
Examples
>>> from compas.geometry import Point >>> from compas.geometry import Vector >>> o = Origin([0, 0, 0], [1, 0, 0], [0, 1, 0]) >>> o = Origin(Point(0, 0, 0), Vector(1, 0, 0), Point(0, 1, 0))
