Random direction of each particle after it has been emitted, between direction1 and direction2 vectors.
direction2Search playground for direction2
Random direction of each particle after it has been emitted, between direction1 and direction2 vectors.
Methods
apply
Called by the GPUParticleSystem to setup the update shader
Parameters
uboOrEffect: UniformBufferEffectCommonAccessor
defines the update shader
Returns void
build
Creates the structure of the ubo for this particle emitter
Parameters
ubo: UniformBuffer
ubo to create the structure for
Returns void
cloneSearch playground for clone
Clones the current emitter and returns a copy of it
Returns PointParticleEmitter
the new emitter
get
Returns the string "PointParticleEmitter"
Returns string
a string containing the class name
get
Returns a string to use to update the GPU particles update shader
Returns string
a string containing the defines string
parseSearch playground for parse
Parse properties from a JSON object
Parameters
serializationObject: any
defines the JSON object
Returns void
serializeSearch playground for serialize
Serializes the particle system to a JSON object.
Returns any
the JSON object
start
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
start
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
Particle emitter emitting particles from a point. It emits the particles randomly between 2 given directions.
