InstancedFlow class

A helper class for creating instanced versions of flow, where the instances are placed on the curve.

Constructors

InstancedFlow(dynamic count, dynamic curveCount, dynamic geometry, dynamic material)
    • @param {number} count The number of instanced elements
      • @param {number} curveCount The number of curves to preallocate for
      • @param {Geometry} geometry The geometry to use for the instanced mesh
      • @param {Material} material The material to use for the instanced mesh
    • factory
    InstancedFlow.create(dynamic mesh, dynamic curveCount)

    Methods

    moveAlongCurve(dynamic amount) → dynamic
    inherited
    moveIndividualAlongCurve(dynamic index, int offset) → dynamic
  • Move an individual element along the curve by a specific amount *
    • @param {number} index Which element to update
      • @param {number} offset Move by how much
    • noSuchMethod(Invocation invocation) → dynamic
    Invoked when a nonexistent method or property is accessed.
    inherited
    setCurve(dynamic index, dynamic curveNo) → dynamic
  • Select which curve to use for an element *
    • @param {number} index the index of the instanced element to update
      • @param {number} curveNo the index of the curve it should use
    • toString() → String
    A string representation of this object.
    inherited
    updateCurve(dynamic index, dynamic curve) → dynamic
    inherited
    writeChanges(dynamic index) → dynamic
  • The extra information about which curve and curve position is stored in the translation components of the matrix for the instanced objects
    • This writes that information to the matrix and marks it as needing update. *
      • @param {number} index of the instanced element to update

    • Operators

    operator ==(Object other) → bool
    The equality operator.
