ApplyDeformByCage

Introduced

2.0

Description

Applies a deformation by cage. Cage deformations allow you to use a low-resolution geometry to drive the deformation of a high-resolution object. They are similar to arbitrarily shaped lattices.

Each point on the deformed object is weighted to the points or polygons on the cage, similarly to how an envelope's points are weighted to its deformers. However, you cannot paint the weight assignments nor adjust them manually. You can also have multiple cage deformations on the same object, unlike envelopes.

This is the equivalent of using the ApplyOp command with the CageDeform operator. For more information on operators and their connection sets, see Operator Presets.

Scripting Syntax

ApplyDeformByCage( [ConnectionSet], [ConstructionMode] )

Parameters

Parameter

Type

Description

ConnectionSet [in/out]

ConnectionSet

Specifies the objects connected to an operator.

The first group of the ConnectionSet contains vertex based objects. The second group of the ConnectionSet contains the deformer (cage) objects.

See Operator Presets for details on the connection set required for this operator.

Default Value: Currently selected objects are used as the main group.

Warning: An error occurs if the connection set is invalid. Please verify the connection set required for this operator to avoid breaking your scripts.

ConstructionMode

siConstructionMode

The mode indicating the purpose of the deformations.

Default Value: Current construction mode.

Return Value

Returns an XSICollection that contains the CageAutoAssignOp and CageDeformOp operators created.

Examples

VBScript Example

'This example creates a cage deformer (cube) over a sphere and a torus.
'Then, the cube is deformed by a taper, and the deformation is reflected
'on the sphere and the torus because of the DeformByCage operator.

NewScene

dim obj, obj1, cage

set obj = CreatePrim( "Sphere", "MeshSurface" )
set obj1 = CreatePrim( "Torus", "MeshSurface" )
set cage = CreatePrim( "Cube", "MeshSurface" )

ApplyDeformByCage obj & "," & obj1 & ";" & cage

'If we deform the cage, it will deform obj and obj1:
ApplyOp "Taper", cage, 3, siPersistentOperation
