GetFacetData Method

Description

Returns the number of facets and the number of points on the facets for the referenced object. If Tolerance <= 0, then data is returned from the geometry cache, and not from Parasolid.

Syntax

Visual Basic
Public Sub GetFacetData( _ ByVal Tolerance As Double, _ ByRef FacetCount As Long, _ ByRef Points() As Double, _ Optional ByRef Normals As Variant, _ Optional ByRef TextureCoords As Variant _ )

Visual Basic

Public Sub GetFacetData( _
   ByVal Tolerance As Double, _
   ByRef FacetCount As Long, _
   ByRef Points() As Double, _
   Optional ByRef Normals As Variant, _
   Optional ByRef TextureCoords As Variant _
)

Parameters

Tolerance: Chordal tolerance between a curve and its facet edges, i.e. upper bound on distance from chord to the curve it approximates. This distance is in Meters.
FacetCount: Returns the number of facets for the referenced object.
Points: Returns the number of points for the associated facet on the referenced object.
Normals: Returns a safe array that contains the facets' normals.
TextureCoords: Returns a safe array that contains the facets' u,v coordinates.
