particle to spline

 

 

This node will connect input particles into a spline shape.

 

 

[Inputs]

 

#Particle Stream - This pin requires a particle stream to be connected for Trail, Neighbours and Cluster types.

 

Enabled - Enable or disable node evaluation.

 

Save To Cache - Enables splines saving to cache.

 

 

Properties

Type - This option lets user to choose how particles are going to be organized into spline shapes. There are four available options:

  • Trail - This option follows the motion of each particle on the input. Each particle trajectory forms one spline shape.
  • Neighbours - Lets you connect particle with its neighbours. Connections are re-created on each frame.
  • Fibers - Each fiber will become one spline shape.
  • Cluster - Particles within the same cluster group will form once spline.

 

Smooth Spline - This will create a smooth spline instead of linear.

 

Segments - Refinement steps for the smooth spline.

 

Knot Radius - Knot radius is used later during the spline shape meshing.

 

Spline Color - Defines a color for each spline. This color can be used from within Arnold shaders by using the User Data RGB Arnold Map and setting fxp_color for Attribute. Also make sure to enable Color export from the NodeWorks menu.

 

 

 

Trail Properties

Min Knot Distance - Use this parameter to avoid very closely spaced spline knots.

 

Trail Mode - There are two trail modes.

  • Continuous - Once the splines reaches its Maximum Length, it will continue to evolve.
  • Stop - Once the splines reaches its Maximum Length, it will stop.

 

Maximum Length - Maximum length of the spline.

 

Maximum Length - Maximum length variation.

 

Remove When Deleted - Removes the spline when particle is deleted.

 

 

Neighbors Properties

Count - Maximum neighbours count.

 

Search Radius - Only particles within this radius will be searched for.

 

Fibers Properties

Merge Fibers - Enable this option to merge individual fibers into one continuous fiber, such as rope.

 

 

Display

Enable Display - Enable fibers and knots display.

 

Display Reduce - Reduce the number of linear knots to display.

 

Show Knots - Display spline knots.

 

Knot Color - Set knot color for display.

 

Show Radius - Display knot radius.
