SurfaceEvaluator.getNormalsAtParameters Method

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

Description

Gets the surface normal at a number of parameter positions on the surface.

Syntax

"surfaceEvaluator_var" is a variable referencing a SurfaceEvaluator object.

(returnValue, normals) = surfaceEvaluator_var.getNormalsAtParameters(parameters)
 

#include <Core/Geometry/SurfaceEvaluator.h

// Declare the output arguments.
Point2D[] parameters;
Vector3D[] normals;
boolean returnValue = surfaceEvaluator_var->getNormalsAtParameters(parameters, normals);

Return Value

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

Parameters

Name Type Description
parameters Point2D[] The array of parameter positions to return the normal at. Each parameter position must be with the range of the parameter extents as verified by isParameterOnFace.
normals Vector3D[] The output array of normals for each parameter position on the surface. The length of this array will be the same as the length of the parameters array provided.
