CurveEvaluator2D.getTangent Method

Parent Object: CurveEvaluator2D
Defined in namespace "adsk::core" and the header file is <Core/Geometry/CurveEvaluator2D.h>

Description

Get the tangent to the curve at a parameter position on the curve.

Syntax

Python
C++

"curveEvaluator2D_var" is a variable referencing a CurveEvaluator2D object.

(returnValue, tangent) = curveEvaluator2D_var.getTangent(parameter)


#include <Core/Geometry/CurveEvaluator2D.h

// Declare the output arguments.
double parameter;
Ptr<Vector2D> tangent;
boolean returnValue = curveEvaluator2D_var->getTangent(parameter, tangent);

Return Value

Type	Description
boolean	Returns true if the tangent was successfully returned.

Parameters

Name	Type	Description
parameter	double	The parameter position to return the tangent at. This value must be within the range of the parameter extents as provided by getParameterExtents.
