CurveEvaluator3D.getTangents Method

Parent Object: CurveEvaluator3D
Defined in namespace "adsk::core" and the header file is <Core/Geometry/CurveEvaluator3D.h>

Description

Get the tangent to the curve at a number of parameter positions on the curve.

Syntax

Python
C++

"curveEvaluator3D_var" is a variable referencing a CurveEvaluator3D object.

(returnValue, tangents) = curveEvaluator3D_var.getTangents(parameters)


#include <Core/Geometry/CurveEvaluator3D.h

// Declare the output arguments.
double[] parameters;
Vector3D[] tangents;
boolean returnValue = curveEvaluator3D_var->getTangents(parameters, tangents);

Return Value

Type	Description
boolean	Returns true if the tangents were successfully returned.

Parameters

Name	Type	Description
parameters	double[]	The array of parameter positions to return the tangent at. Each parameter value must be within the range of the parameter extents as provided by getParameterExtents.
tangents	Vector3D[]	The output array of tangent vectors for each position on the curve. The length of this array will be the same as the length of the parameters array provided.
