EvaluateNormals (Geometry) *

Introduced

5.0

Description

Evaluates the normals at the surface locations defined by the point locator data. The returned normals are in geometry's local space reference.

In the case of PolygonMesh, various computation methods are available.

An example using this method can be found in PointLocatorData object's description.

Scripting Syntax

    Geometry.EvaluateNormals( PointLocators, [ComputationMethod], [Indices] )

C# Syntax

    Object Geometry.EvaluateNormals( PointLocatorData in_pPtLocators, Int32 in_ComputationMethod, Object in_pPointLocatorsIndices );

Parameters

Parameter | Type | Description
PointLocators | PointLocatorData | Point locators to be evaluated.
ComputationMethod | siNormalComputationMethod | Normals computation method. Default Value: siInterpolatedVertexGeometricNormals
Indices | 1-dimensional Array | Indices of the point locators to be evaluated (all in not specified).

Return Value

2-dimensional Array, (the first dimension contains the x,y,z values).
