CurveEvaluator2D.getTangent Method
Parent Object:
CurveEvaluator2DDefined 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
"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
| boolean |
Returns true if the tangent was successfully returned. |
Parameters
| 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. |
| tangent |
Vector2D |
The output tangent vector at the curve position. |
