HasNormals Property (Multipatch)

In This Topic

Gets a value indicating if this multipatch has normals.

Syntax

C#
Visual Basic (Declaration)

public bool HasNormals {get;}

Public ReadOnly Property HasNormals As Boolean

Remarks

The normals of a 3D object are used for lighting. They define the direction that each face will reflect light. They are usually perpendicular to the geometry but can also be defined in other directions.

Example

Get the normal coordinate of a multipatch

// <summary>
// This method gets the normal coordinate of a multipatch and does something with it.
// </summary>
// <param name="multipatch">The input multipatch.</param>
// <param name="patchIndex">The index of the patch (part) for which to get the normal.</param>
public void DoSomethingWithNormalCoordinate(Multipatch multipatch, int patchIndex)
{
  if (multipatch.HasNormals)
  {
    // If the multipatch has normals, then the number of normals is equal to the number of points.
    int numNormals = multipatch.GetPatchPointCount(patchIndex);

    for (int pointIndex = 0; pointIndex < numNormals; pointIndex++)
    {
      Coordinate3D normal = multipatch.GetPatchNormal(patchIndex, pointIndex);

      // Do something with the normal coordinate.
    }
  }
}
