Houdini 19.0 Nodes VOP nodes

Pose Difference VOP node

Compute the difference between point transforms on two SOP skeletons.

Since 18.5

This node allows you to store the difference between the transform on a given point on a given geometry to a corresponding point on the reference geometry'.

The difference can be computed between world or local transforms, or any custom Matrix attribute that is present on both inputs (a rest_transform attribute, for example).

Parameters

Signature

Default Inputs

The Point and Reference Point inputs are specified by point index.

Point Name

The Point and Reference Point inputs are specified by point name.

File

Specifies the input or operator location for the geometry file on which the Point is found.

Geometry Path

Specifies the operator path that points to a SOP node.

This parameter is only available when File is set to Operator Path.

Reference File

Specifies the input or operator location for the geometry file on which the queried Reference Point is found.

Reference Geometry Path

Specifies the operator path that points to a SOP node.

This parameter is only available when Reference File is set to Operator Path.

Point

The index or name of the point whose transform we wish to compare with the Reference Point.

Reference Point

The index or name of the point whose transform will be compared with the Point.

Transform Attribute

The name of the matrix4 attribute to use for comparison. If left blank, the world transform (@P and 3@transform) of each point will be used.

Components

Which parts of the difference transform to output.

Invert

Invert the returned transform.

Translate In Reference Space

If enabled, the translation difference will be inversely scaled by the Reference Point’s transform. You may wish to disenable this option if you wish to re-combine the result of this operation to another transform downstream in an additive fashion.
