    GetMaterialShininess Method
    In This Topic
    Gets the shininess of the specified material.
    Syntax
    public int GetMaterialShininess( 
       int materialIndex
    )
    Public Function GetMaterialShininess( _
       ByVal materialIndex As Integer _
    ) As Integer

    Parameters

    materialIndex
    The index of the material. Must be greater than or equal to zero and less than MaterialCount. Get the index for a patch by calling GetPatchMaterialIndex.
    Exceptions
    ExceptionDescription
    The material index must be >= 0.
    The material index must be less than the number of materials in the multipatch.
