Deform Strand Extrusion

 
 
 

Deforms the geometry created by Create Extrusion Along Strands, when that compound's Mute Deformation option is on. This allows you to create the geometry in one tree, and deform it along the strand in another tree higher up in the construction stack. See Creating an Extrusion Along Strands.

Tasks: Deformation/Effects

Output Ports: Execute

Base Up Vector

Mute

Disables the effect.

Remove Strand Position

Ignores the specified elements in the StrandPosition array. This is useful when using strand compounds that set StrandPosition[0] to the particles' PointPosition.

This option should be set to the same value as in Create Extrusion Along Strands.

Rotate Normal

Twists the cross-section along the length of the strand.

Index

The index in the Strand Position array to ignore.

This option should be set to the same value as in Create Extrusion Along Strands.

UpVector Mode

Controls the orientation of the cross-section:

  • From Emit Location calculates the orientation from the particles' EmitLocation. If that attribute is undefined, it falls back to From Particle Orientation.
  • From Particle Orientation uses the particles' Orientation. If that attribute is undefined, it falls back to From Strand First Tangent.
  • From Strand First Tangent calculates the orientation from the first segment in each strand.
  • From Custom Vector uses the UpVector specified below.

UpVector

The vector to use when UpVector Mode is set to From Custom Vector.

Rotation Angle

The amount of rotation along the length of the strand.
