Frame
- class compas.geometry.Frame(point, xaxis, yaxis, **kwargs)[source]
Bases:
Primitive
A frame is defined by a base point and two orthonormal base vectors.
- Parameters
- Attributes
point (
Point
) – The base point of the frame.xaxis (
Vector
) – The local X axis of the frame.yaxis (
Vector
) – The local Y axis of the frame.zaxis (
Vector
, read-only) – The Z axis of the frame.normal (
Vector
, read-only) – The normal of the base plane of the frame.quaternion (
Quaternion
, read-only) – The quaternion from the rotation given by the frame.axis_angle_vector (
Vector
, read-only) – The axis-angle vector representing the rotation of the frame.
Notes
All input vectors are orthonormalized when creating a frame, with the first vector as starting point.
Examples
>>> from compas.geometry import Point >>> from compas.geometry import Vector >>> f = Frame([0, 0, 0], [1, 0, 0], [0, 1, 0]) >>> f = Frame(Point(0, 0, 0), Vector(1, 0, 0), Vector(0, 1, 0))
