Constructors

  • Creates a new instance PointParticleEmitter

    Returns PointParticleEmitter

Properties

direction1: Vector3

Random direction of each particle after it has been emitted, between direction1 and direction2 vectors.

direction2: Vector3

Random direction of each particle after it has been emitted, between direction1 and direction2 vectors.

Methods

  • applyToShader(uboOrEffect: UniformBufferEffectCommonAccessor): void
  • Called by the GPUParticleSystem to setup the update shader

    Parameters

    • uboOrEffect: UniformBufferEffectCommonAccessor

      defines the update shader

    Returns void

  • getClassName(): string
  • Returns the string "PointParticleEmitter"

    Returns string

    a string containing the class name

  • getEffectDefines(): string
  • Returns a string to use to update the GPU particles update shader

    Returns string

    a string containing the defines string

  • parse(serializationObject: any): void
  • Parse properties from a JSON object

    Parameters

    • serializationObject: any

      defines the JSON object

    Returns void

  • serialize(): any
  • Serializes the particle system to a JSON object.

    Returns any

    the JSON object

  • startDirectionFunction(worldMatrix: Matrix, directionToUpdate: Vector3, particle: Particle, isLocal: boolean): void
  • Called by the particle System when the direction is computed for the created particle.

    Parameters

    • worldMatrix: Matrix

      is the world matrix of the particle system

    • directionToUpdate: Vector3

      is the direction vector to update with the result

    • particle: Particle

      is the particle we are computed the direction for

    • isLocal: boolean

      defines if the direction should be set in local space

    Returns void

  • startPositionFunction(worldMatrix: Matrix, positionToUpdate: Vector3, particle: Particle, isLocal: boolean): void
  • Called by the particle System when the position is computed for the created particle.

    Parameters

    • worldMatrix: Matrix

      is the world matrix of the particle system

    • positionToUpdate: Vector3

      is the position vector to update with the result

    • particle: Particle

      is the particle we are computed the position for

    • isLocal: boolean

      defines if the position should be set in local space

    Returns void
