NormalDisplacement
Overview
NormalDisplacement displaces geometry using scalar inputs to determine strength of displacement.
When combining two NormalDisplacement nodes, it is more efficient to layer the input data using LayerMap or OpMap than using CombineDisplacement.

General attributes
bound_padding
Float
default: 0.0
bound padding defines how much to extend the bounding box of the object. Keep this value as low as possible unless the geometry skips tessellation because control cage bounding box is out of camera frustum but the displacement stretch out of the original object bounding box (pre-displacement). Setting the bound padding too large will consume more memory and tessellation time.
height
Float bindable
default: 1.0
This parameter is used as the initial displacement before the zero_value and height_multiplier are applied.
height_multiplier
Float bindable
default: 1.0
Multiply the computed (post zero-value) height with this factor.
zero_value
Float
default: 0.0
This value is added to the displacement before applying the height_multiplier.
