Deforms captured points according to metaball deformations.
Connect the output of a Capture Metaball SOP to the input of this operator to make Houdini deform the captured skin geometry as the metaballs deform. This node uses the attributes created by the Capture Metaball SOP to determine which surfaces are controlled by which metaball groups.
The density of the metaball where it captured the skin geometry at the capture frame controls how much influence the metaball has when it deforms the skin geometry. This density is multiplied by the weight of the group that metaball is contained in. Group weights are specified by the Capture Metaball and Capture Layer Paint operators.
|Normalize Group Weights|
Normalize group weights before performing the deformation.
Deforms the point normals to match the deformation of the points.
|Deform Vector Attributes|
Deforms the vector attributes to match the deformation of the points.
Vector attributes to deform.
|Deform Quaternion Attributes|
Deforms the quaternion attributes to match the deformation of the points.
Quaternion (Float) attributes to deform.
Use this parameter to have points blend their deformation position between a fully deformed position and a rest pose position. This is primarily meant to be used with metaball fields defined by the Muscle Object. The Rest Anchor parameter on this object establishes a rest position relative to the specified rest anchor for each metaball in the muscle geometry. Note that to generate the effect of muscles sliding under the surface of a character’s skin, the skin must be Inflated over the muscle surface. The Deform Muscle SOP consolidates these effects in to a single operator.
The amount of sliding to allow during deformation when Enable Sliding is on. If this parameter is set to zero, then points in the captured geometry stick perfectly to the capturing metaballs during deformation and no sliding occurs. If this parameter is set to one, then points do not stick to the underlying metaballs at all. This parameter may be modified on a per-point basis using the Slide Modifier Paint operation.
This must be the output of a Capture Metaball
SOP (that is, geometry with the
The deformed geometry. The output does not include the metaballs.
