SplitPolygon

Splits the given set of polygons using the split pattern passed as an argument (e.g.: cross, diamond, triangles, etc).

Note: This command uses output arguments. C# and some scripting languages (such as JScript, PerlScript and Python) don't support arguments passed by reference. Normally you can get the output arguments via either XSIApplication.ExecuteCommand method (C#) or the ISIVTCollection (scripting languages), but this command already returns a value.

The only available workaround in this case is to create a VBScript custom command which returns both the output arguments and the return value in one array. For details, see What Happens when the Function Already Returns a Value?.

Return Value

Parameters

Parameter	Type	Description
ConnectionSet	ConnectionSet	Specifies the polygons to split. See Operator Presets for details on the connection set required for this operator. Default Value: Currently selected components are used. Warning: An error occurs if the connection set is invalid. Please verify the connection set required for this operator to avoid breaking your scripts.
TanX	Double	X parameter w/r to the local frame of the polygon(s) where to put the split point
TanY	Double	Y parameter w/r to the local frame of the polygon(s) where to put the split point
TanZ	Double	Z parameter w/r to the local frame of the polygon(s) where to put the split point Default Value: This is effectively a signed distance from the polygon plane where the split point is. This only makes sense if SplitPolygonType is "siByTheVertices"; otherwise the polygon will become nonplanar.
SplitPolygonType	siSplitPolygonType	type of split Default Value: siUnspecified
ImmediateMode	siOperationMode	Specifies whether or not the operator should be immediately frozen. Default Value: siPersistentOperation
NewPointID	Integer	ID of the new point created at (TanX,TanY) by the operation (-1 is returned if SplitPolygonType is "siDiamond..." as no point is created)

Examples

1. VBScript Example

NewScene
CreatePrim "Cylinder", "MeshSurface" 
SplitPolygon "cylinder.poly[12-36]", 0.0, 0.0, 0.5, siByTheVertices, True

2. VBScript Example

' Create a grid and split some polygons by the Edges MidPoints 
NewScene
CreatePrim "Grid", "MeshSurface"
SetValue "grid.polymsh.geom.subdivu", 4
SetValue "grid.polymsh.geom.subdivv", 4
SplitPolygon "grid.poly[0,2,5,7,8,10,13,15]", 0.0, 0.0, 0.5, siByTheEdgesMidPoints, True
