Description This subroutine sets the flag for a Faceted Surface that specifies whether the surface should use vertex normal data.
Syntax FacetedSurfSetUseVertexNormals( fsNode, useNormals )
Parameters fsNode As Long Node number of the faceted surface being modified.
useNormals As Boolean Flag specifying whether the surface should use vertex normal data.
Example The following example queries a faceted surface for vertex normal data and then sets the flag for their use as appropriate.
Sub Main Dim fsNode As Long Dim hasNormals As Boolean fsNode = FindFullName( "Geometry.Elem 1.Faceted Surface Test" ) hasNormals = FacetedSurfGetHasVertexNormals( fsNode ) If hasNormals Then FacetedSurfSetUseVertexNormals( fsNode, True ) Else FacetedSurfSetUseVertexNormals( fsNode, False ) End If
End Sub
