Spline Displacement (in development, Node)
This node evaluates the distance to a point on a spline and outputs a displacement to that closest point.
Controls
Spline
Select the Spline Primitive to use in this node.
World Coordinates
Evaluates the spline in world coordinates.
Minimum Distance
Maximum Distance
These two define the minimum and maximum range for the displacement. Anything at or below the minimum will be 100% displaced, anything at or beyond the maximum will not be displaced at all.
Strength
This is the strength of the displacement, as a value from 0 to 1, and takes the Function input into account as well. It's almost identical to the normalised output in the Spline Proximity (node). This can be used like a weight to, for example, drive the positioning of instances.
Distance Evaluation
This controls how the distance to the spline, which drives the displacement, is computed.
- 3D Evaluates the distance in all three directions.
- YZ Only evaluates on a YZ plane, ignoring the along X.
- XZ Only evaluates on a XZ plane, ignoring the along Y.
- XY Only evaluates on a XY plane, ignoring the along Z.
Connections
Inputs
Position
The position to find the closes point in the spline to. If this is not connected, then the current position provided by LightWave 3D is used.
MinDistance/MaxDistance
Strength
Function
Outputs
Displacement
A displacement vector that can be plugged directly into the Input of the Displacement Node Editor.
Axis Displacement
If the Distance Evaluation is not set to 3D, this will output a displacement vector along the axis that is not used for the evaluation.
For example, if the Distance Evaluation is set to XZ, then the Axis Displacement will return a vector along the Y axis only.
Strength
This is the strength of the displacement, as a value from 0 to 1, and takes the Function input into account as well. It's almost identical to the normalised output in the Spline Proximity (node). This can be used like a weight to, for example, drive the positioning of instances.
Position
The position of the closes point on the spline.
Direction
The direction to the closest point on the spline.
Distance
The distance to the closest point on the spline.
