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

Description

Get the parameter position that correspond to a point on the surface. For reliable results, the point should lie on the surface within model tolerance. If the point does not lie on the surface, the parameter of the nearest point on the surface will generally be returned.

Syntax

(returnValue, parameter) = surfaceEvaluator_var.getParameterAtPoint(point)
 

#include <Core/Geometry/SurfaceEvaluator.h

// Declare the output arguments.
Ptr<Point3D> point;
Ptr<Point2D> parameter;
boolean returnValue = surfaceEvaluator_var->getParameterAtPoint(point, parameter);

Return Value

Type Description
boolean Returns true of the parameter was successfully returned.

Parameters

Name Type Description
