AxisConstraint

Extends: Constraint
Defined in: src/constraints/AxisConstraint.js:14

Defines one or many relationships between an infinite axis and single particles.

Orientaiton of the axis is defined by 2 points: axisA and axisB.

var axisA = 0, axisB = 1
var a = 2, b = 3, c = 4
var single = AxisConstraint.create(axisA, axisB, a)
var many = AxisConstraint.create(axisA, axisB, [a, b, c])
AxisConstraint( axisA, axisB, a )
src/constraints/AxisConstraint.js:14
  • axisA Int

    Particle index defining start of axis

  • axisB Int

    Particle index defining end of axis

  • a Int | Array

    Particle index or list of many indices

applyConstraint( index, p0, p1 ) protected
Defined in Constraint: src/constraints/Constraint.js:90 Apply constraint to one set of particles defining a constrint relation. Called _count times per relaxation loop.
  • index Int
    Constraint set index
  • p0 Float32Array (Vec3)

  • p1 Float32Array (Vec3)

create( ) static
src/constraints/AxisConstraint.js:41

Create instance, accepts constructor arguments.

setAxis( a, b )
src/constraints/AxisConstraint.js:49

setIndices( indices, [a] )
Defined in Constraint: src/constraints/Constraint.js:73 Set particle indices with Array or list of arguments.
