Method #

This node generates a delaunay triangulated mesh based on an input particle system. The mesh always generates facing the Z axis, so scenes which use this node must either be built with this in mind, or the node can be transformed after the fact.

This process is computationally expensive, so its advised to use a limited number of particles.
Does not function with Ray Tracing nodes.

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.

ParameterDetails
Position XMove along the local x-axis.
Position YMove along the local y-axis.
Position ZMove along the local z-axis.
Rotation HeadingRotate around the local y-axis.
Rotation PitchRotate around the local x-axis.
Rotation BankRotate around the local z-axis.
Scale XScale along the local x-axis.
Scale YScale along the local y-axis.
Scale ZScale along the local z-axis.

Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.

ParameterDetails
Position XToggle inheritance of the X Position from the parent.
Position YToggle inheritance of the Y Position from the parent.
Position ZToggle inheritance of the Z Position from the parent.
Rotation HeadingToggle inheritance of the Rotation Heading from the parent.
Rotation PitchToggle inheritance of the Rotation Pitch from the parent.
Rotation BankToggle inheritance of the Rotation Bank from the parent.
Scale XToggle inheritance of the X Scale from the parent.
Scale YToggle inheritance of the Y Scale from the parent.
Scale ZToggle inheritance of the Z Scale from the parent.
World Position OnlyInherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit TimeToggle inheritance of time from the parent.

These properties control the core behaviours of the node.

ParameterDetails

Update Tessellation TimeThe rate at which the voronoi tessellation is regenerated.
Subdivision AmountHow much output mesh is subdivided.
Alpha ThresholdLimits the particles used based on their alpha values.
Line AlphaAlpha value for the lines between points.
Constant Colour BlendHow much of a constant colour is blended into the scene.
Depth Displace AmountDisplace the voronoi effect from the particle system.
Optical Flow AmountHow much the optical flow affects the image.
Particles To SkipHow many particles are skipped
Colour SourceColour source for the image.
Cull Triangles By AlphaChoose whether triangles are culled by their alpha value.
