Import detail

from ansys.geometry.core.shapes.curves.line import LineEvaluation

Property detail

property LineEvaluation.line: Line

Line being evaluated.

property LineEvaluation.parameter: float

Parameter that the evaluation is based upon.

Method detail

LineEvaluation.position() → ansys.geometry.core.math.point.Point3D

Position of the evaluation.

Returns:

Point3D

Point that lies on the line at this evaluation.

LineEvaluation.tangent() → ansys.geometry.core.math.vector.UnitVector3D

Tangent of the evaluation.

Returns:

UnitVector3D

Tangent unit vector to the line at this evaluation.

Notes

This is always equal to the direction of the line.

LineEvaluation.first_derivative() → ansys.geometry.core.math.vector.Vector3D

First derivative of the evaluation.

The first derivative is always equal to the direction of the line.

Returns:

Vector3D

First derivative of the evaluation.

LineEvaluation.second_derivative() → ansys.geometry.core.math.vector.Vector3D

Second derivative of the evaluation.

The second derivative is always equal to a zero vector Vector3D([0, 0, 0]).

Returns:

Vector3D

Second derivative of the evaluation, which is always Vector3D([0, 0, 0]).

LineEvaluation.curvature() → float

Curvature of the line, which is always 0.

Returns:

Real

Curvature of the line, which is always 0.
