Property detail

property LineEvaluation.line: Line

Line being evaluated.

property LineEvaluation.parameter: float

Parameter that the evaluation is based upon.

property LineEvaluation.position: ansys.geometry.core.math.point.Point3D

Position of the evaluation.

Returns:

Point3D

Point that lies on the line at this evaluation.

property 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.

property 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.

property 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]).

property LineEvaluation.curvature: float

Curvature of the line, which is always 0.

Returns:

Real

Curvature of the line, which is always 0.
