cluster

Go to: Related nodes. Attributes.

The cluster node deforms one or more geometries by transforming them by some percentage of the transformation of another object in the scene. The default percentage is one, so the default cluster will rigidly deform the geometries.

A different percentage can be associated with each CV in the deformed object.

The accuracy of the deformation is controlled by the percentResolution attribute.

The envelope attribute can be used to globally attenuate the amount of deformation.

Long name (short name)	Type	Default	Flags
bindState (bs)	bool	false
not used
clusterXforms (x)	compound	n/a
the bundled cluster transforms
preMatrix (pre) matrix identity Represents the transformation in the DAG above the weighted node.
weightedMatrix (wt) matrix identity cluster weighted matrix
postMatrix (post) matrix identity Represents the transformation in the DAG below the weighted node.
geomMatrix (gm)	matrix	identity
Matrix to set account for the geom matrix at cluster creation time.
angleInterpolation (ait)	enum	0
The direction of angle interpolation. In most cases 0 (Closest) will work the best. However, if components appear to be rotating in the wrong direction, a value of 1 (Positive) or 2 (Negative) may be needed.
percentResolution (ptr)	float	5
resolution by which cluster percents can differ without being lumped together as a single percentage for efficiency
postCompensationMatrix (psc)	matrix	identity
WorldSpace matrix below cluster weighted matrix compensation
preCompensationMatrix (prc)	matrix	identity
WorldSpace matrix above cluster weighted matrix comp (-bs)
bindPreMatrix (pm)	matrix	identity
compensation matrix used when we rigidly deform the geometry
relative (rel)	bool	false
relative => only use weighted node i.e. no pre, post matrix
matrix (ma)	matrix	identity
transform that we will rigidly deform by when all percentages are at one
usePartialResolution (upr)	enum	0
whether or not to use the partial resolution
weightedCompensationMatrix (wcm)	matrix	identity
cluster weighted matrix compensation
