Encapsulates 3D parameterization with normals for pattern generators. Allows selection of Pref and Nref and specification of a coordinate system to transform to. Uses a simple struct to represent bundled dataflow of outputs. This manifold also transforms and outputs a normal as part of the simple struct.
Input Parameters
Scale
Scale the frequency of the feature uniformly in 3D.
Use
| Usage | Value | Default variable | |
|---|---|---|---|
| Current position: P + N | Use the current (displaced) surface position and normal | 0 | P Nn |
| Undisplaced position: Po + NoN | Use the surface position and normal before it was displaced | 1 | Po NoN |
Deform : __Pref + __Nref | Use reference primitive variables in object space | 2 | __Pref __Nref |
| Deform & transform: __WPref + __WNref | Use reference primitive variables in world space | 3 | __WPref __WNref |
You can only use __Pref/__Nref and __WPref/__WNref if these primitive variables have been attached to your geometry. Otherwise the pattern will use P and Nn.
Pref
Name of geometry Pref (Maya uses __Pref/__Nref and __WPref/__WNref).
This field is only used when Use is set to "Deform : __Pref + __Nref" or "Deform & transform: __WPref + __WNref".
If left empty, we assume either __Pref or __WPref, based on the current Use settings.
Nref
Name of geometry Reference Normal (Maya uses __Nref/__WNref by default).
This field is only used when Use is set to "Deform : __Pref + __Nref" or "Deform & transform: __WPref + __WNref".
If left empty, we assume either __NRef or __WNref, based on the current Use settings.
Coordinate System
Name of a coordinate system transform to apply to the manifold. (Maya calls these place3d nodes).
If left empty, we use the position in object-space, as this is what you need for non-deforming objects.
