Birth Spline operator

The Birth Spline operator can be used to birth new particles on the curves of splines.


Splines

  • Spline list: the list of input splines whose curves will be used to birth particles.

Particle birth

Mode
  • Percent Along Spline: particles will be birthed at intervals along splines based on a percentage of their total length.

  • Distance Along Spline: particles will be birthed at intervals along splines based on a distance along their total length.

  • Knots: particles will be birthed on spline knots.

  • Interpolated Knots: particles will be birthed on implicit spline knots, whose interpolated locations are based on the spline’s step and optimization settings.

Interpolation
  • Simple Interpolation: percents and distances along the splines will be relative to sub segment lengths and knot spacing.

  • Normalized Interpolation: percents and distances along the splines will be relative to the normalized spline length, ignoring segments lengths and knot spacing.


  • Start/End: controls the time range in which to birth new particles.

  • Percent %: the percent value used in “percent along spline” mode.

  • Distance: the distance value used in “distance along spline” mode.
