This nodes allows artists to place patterns using a 3D projection as opposed to a 2D application often used for textures reliant on UVs. This allows selection of Pref (for deforming meshes) and specification of a coordinate system to transform to.
Scale the frequency of the feature uniformly in 3D.
|Current position: P||Use the current (displaced) surface position|
|Undisplaced position: Po||Use the surface position before it was displaced|
Deform : __Pref
|Use a reference position primitive variable in object space|
|Deform & transform: __WPref||Use a reference position primitive variable in world space|
You can only use
When using the same 3d noise in the BxDF and the displacement, you should use Po to make sure the patterns are lining up.
Bad: using P Good: using Po Left: P Right: Po
Name of geometry Pref (Maya uses __Pref and __WPref).
This field is only used when Use is set to "Deform : __Pref" or "Deform & transform: __WPref" .
If left empty, we assume either
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.
The 3D manifold.
A float representation of the X component of the manifold.
A float representation of the Y component of the manifold.
A float representation of the Z component of the manifold.
