Geometry.EvaluateNormals
v5.0
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.
Object Geometry.EvaluateNormals( PointLocatorData in_pPtLocators, Int32 in_ComputationMethod, Object in_pPointLocatorsIndices ); |
oArray = Geometry.EvaluateNormals( PointLocators, [ComputationMethod], [Indices] ); |
2-dimensional Array, (the first dimension contains the x,y,z values).
| 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). |
