Voronoi Node
Updated: 22 Mar 2024
Generates a 3D Voronoi pattern for procedurals.
Voronoi Node
Method #
Generates a 3D Voronoi pattern based on an input particle system. If no particle root is plugged in, then a default infinite pattern will be used.
Nodes connected to this node will generally follow the parent child hierarchy. Other Procedural Generator nodes can be configured to combine with this shape using their CSG modes, and displacement nodes will only apply to this shape.
Parameters
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
Parameter Details Position X The objects position along the local x-axis.
Position Y The objects position along the local y-axis.
Position Z The objects position along the local z-axis.
Rotation Heading The objects rotation around the local y-axis.
Rotation Pitch The objects rotation around the local x-axis.
Rotation Bank The objects rotation around the local z-axis.
Scale X The objects scale along the local x-axis.
Scale Y The objects scale along the local y-axis.
Scale Z The objects scale along the local z-axis.
Control the inheritance of the transforms from the parent.
Parameter Details Position Toggle inheritance of the Position from the parent.
Rotation Toggle inheritance of the Rotation from the parent.
Scale Toggle inheritance of the Scale from the parent.
World Position Only Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time Toggle inheritance of time from the parent.
These properties control the core behaviours of the node.
Parameter Details Num Particles Number of particles to be used to generate the voronoi shape.
Mode Select how the voronoi points are sourced.
- Grid : Points of generated grid will be used. this can be scaled and moved using the transformation values.
- Particles : The particles in a particle system are used for the voronoi points. this requires a particle root or particle emitter to be connected.
CSG Mode These options change how a this procedural node combines with the existing of the procedural system.
- Replace : Replaces the previous procedural system with a new procedural shape.
- Union : Simply combines both the new procedural shape and the existing procedural system.
- Intersection : Interesects the new shape with the shape before.
- Subtract : Subtracts the new procedural shape from the existing procedural system.
- Blend : Blends between both the new procedural shape and the existing procedural system, driven by the CSG Blend Weight.
- Union Blend : A combination of union and blend which tries to preserve both objects more, with the blending being driven by the CSG Blend Weight.
- Smooth Union : The new procedural is added to the old, and smoothing (driven by the CSG Blend Weight) is applied to the outcome.
- Smooth Subtract : The new procedural shape is subtracted from the existing procedural system, and smoothing (driven by the CSG Blend Weight) is applied to the outcome.
- Offset : Blends one procedural ontop of the other another withing the area of the original procedural system.
- Custom Code : Allows you to enter your own expression code.
CSG Blend Weight How much the new procedural blends with the old procedurals, depending on the CSG Blend Weight.
