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 Direction FunctionSearch playground for startDirectionFunction
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 Position FunctionSearch playground for startPositionFunction
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 the inside of a hemisphere. It emits the particles alongside the hemisphere radius. The emission direction might be randomized.
