Encapsulates 3D parameterization for pattern generators. Allows selection of Pref This nodes allows artists to place patterns using a 3D projection as opposed to a 2D projection often used for textures reliant on UVs. This allows selection of Pref (for deforming meshes) and specification of a coordinate system to transform to. Uses a simple struct to represent bundled dataflow of outputs.
Input Parameters
Scale
Scale the frequency of the feature uniformly in 3D.

| Usage | Value | Default variable | |
|---|---|---|---|
| Current position: P | Use the current (displaced) surface position | 0 | P |
| Undisplaced position: Po | Use the surface position before it was displaced | 1 | Po |
Deform : __Pref | Use a reference position primitive variable in object space | 2 | __Pref |
| Deform & transform: __WPref | Use a reference position primitive variable in world space | 3 | __WPref |

Why use the un-displaced position ?
When using the same 3d noise in the BxDF and the displacement, you should use Po to make sure the patterns are lining up.

If left empty, we use the position in object-space, as this is what you need for non-deforming objects. |
