This is useful to derive an animatable channel to transform an object about a single axis.
Subset of geometry to transform.
The type of elements referenced in the Group field.
The pivot to do the transform with.
The orientation of the axis to transform with.
Amount of translation along the axis.
Amount of rotation about the axis.
Non-uniform scaling along the axis.
Recompute Point Normals
Recomputes point normals if they exist.
Recompute Affected Normals
Recomputes any normals that are affected by polygons that use both transformed and untransformed points. When transforming the full geometry or full connected components, the results should be the same as when this option is off, i.e. the normals will just be transformed and not recomputed. This does nothing if
P is not being transformed.
Preserve Normal Length
Normal lengths remain unaffected.
Use the inverse of the transformation. This is the transformation which undoes the specified transformation. Two transform SOPs with all parameters but this equal will cancel out each other’s transformation.
If this field is not blank, the node creates a detail attribute with this name, containing a 4×4 matrix representing the applied transform. You can use this, for example, to apply the same transform elsewhere, or reverse the transformation later in the chain.
If the Output attribute already exists, this controls how/whether the node combines the new transform with the existing one in the attribute. "Post-multiplication" applies the transform in the same way as if you wired multiple transform nodes to each other in the network.
CEX, CEY, CEZ
The centroid of the input
GCX, GCY, GCZ
The centroid of the input group
The X extents of the bounding box of the input
The Y extents of the bounding box of the input
The Z extents of the bounding box of the input
SIZEX, SIZEY, SIZEZ
The size of the bounding box of the input
The following examples include this node.
This example demonstrates using the
layer point attribute to improve collisions when simulating multiple layers of Vellum cloth.
