Returns the Position and optionally U tangent, V Tangent,Normal at a given normalized UV value.

Note: This method uses output arguments. C# and some scripting languages (such as JScript and PerlScript) don't support arguments passed by reference. However, there is a alternate version of this method which is considered safe to use with C#, JScript and PerlScript: NurbsSurface.EvaluateNormalizedPosition2.

NurbsSurface.EvaluateNormalizedPosition( Double in_dUValueNormalized, Double in_dVValueNormalized, Object& out_pPosition, Object& out_pUTangent, Object& out_pVTangent, Object& out_pNormal );

NurbsSurface.EvaluateNormalizedPosition( UValueNormalized, VValueNormalized, [Position], [UTangent], [VTangent], [Normal] );

Parameter	Type	Description
UValueNormalized	Double	The normalized UValue(0.0 to 1.0) at which we want to evaluate the surface.
VValueNormalized	Double	The normalized VValue(0.0 to 1.0) at which we want to evaluate the surface.
Position	SIVector3 (contains the position)	Position at the given UV.
UTangent	SIVector3 (contains the U tangent)	Tangent in U at the given UV.
VTangent	SIVector3 (contains the V tangent)	Tangent in V at the given UV.
Normal	SIVector3 (contains the normal)	Normal at the given UV.

VBScript Example

set oRoot = Application.ActiveProject.ActiveScene.Root
set oSphere = oRoot.AddGeometry( "Sphere", "NurbsSurface" )
oSphere.ActivePrimitive.Geometry.Surfaces(0).EvaluateNormalizedPosition _
	0.5, 0.5, oPosition,oUTangent,oUTangent,oNormal
LogMessage "The position at 0.5, 0.5 is x :" &  oPosition.x	& " y: " & _
	oPosition.y & " z: " & oPosition.z
