ResamplePrimitiveVariables

Resamples the list of primitive variables in Names for either mesh, curves or point primitives.

The reampling algorithm either expands or reduces each primitive variable's data based on the primitive type, primitive variable source interpolation and target interpolation as detailed in the tables below

Mesh Primitive

source / target	Constant	Uniform	Vertex	FaceVarying
Constant	-	copy	copy	copy
Uniform	average	-	copy	copy
Vertex / Varying	average	polygon average	-	copy
FaceVarying	average	polygon average	vertex average	-

Curves Primitive

source / target	Constant	Uniform	Vertex	FaceVarying
Constant	-	copy	copy	copy
Uniform	average	-	copy	copy
Vertex	average	curve average	-	evaluated
Varying / FaceVarying	average	curve average	evaluated	-

Points Primitive

source / target	Constant	Uniform	Vertex / FaceVarying
Constant	-	copy	copy
Uniform	copy	-	copy
Vertex / Varying / FaceVarying	average	average	-

evaluated : spline evaluated to approximate vertex or varying values

copy : expand source values to target based on topology

average : calculate the mean of the primitive variable (either for the whole primitive, for face / curve or vertex)

user

Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.

out

The processed output scene.

enabled

The on/off state of the node. When it is off, the node outputs the input scene unchanged.

in

The input scene

filter

The filter used to control which parts of the scene are processed. A Filter node should be connected here.

names

The names of the primitive variables to be affected. Names should be separated by spaces, and Gaffer’s standard wildcard characters may be used.

invertNames

When on, the primitive variables matched by names are unaffected, and the non-matching primitive variables are affected instead.

interpolation

Target interpolation for the primitive variables
