类: ParticleSystem
A ParticleSystem manages the updating and display of a collection of particles.
参数
Object with the following properties:
参数
Whether to display the particle system.
参数
The callback function to be called each frame to update a particle.
参数
The particle emitter for this system.
参数
The 4x4 transformation matrix that transforms the particle system from model to world coordinates.
参数
The 4x4 transformation matrix that transforms the particle system emitter within the particle systems local coordinate system.
参数
The number of particles to emit per second.
参数
An array of ParticleBurst, emitting bursts of particles at periodic times.
参数
Whether the particle system should loop its bursts when it is complete.
参数
Sets the scale to apply to the image of the particle for the duration of its particleLife.
参数
The initial scale to apply to the image of the particle at the beginning of its life.
参数
The final scale to apply to the image of the particle at the end of its life.
参数
Sets the color of a particle for the duration of its particleLife.
参数
The color of the particle at the beginning of its life.
参数
The color of the particle at the end of its life.
参数
The URI, HTMLImageElement, or HTMLCanvasElement to use for the billboard.
参数
If set, overrides the minimumImageSize and maximumImageSize inputs that scale the particle image's dimensions in pixels.
参数
Sets the minimum bound, width by height, above which to randomly scale the particle image's dimensions in pixels.
参数
Sets the maximum bound, width by height, below which to randomly scale the particle image's dimensions in pixels.
参数
Sets if the size of particles is in meters or pixels. <code>true</code> to size the particles in meters; otherwise, the size is in pixels.
参数
If set, overrides the minimumSpeed and maximumSpeed inputs with this value.
参数
Sets the minimum bound in meters per second above which a particle's actual speed will be randomly chosen.
参数
Sets the maximum bound in meters per second below which a particle's actual speed will be randomly chosen.
参数
How long the particle system will emit particles, in seconds.
参数
If set, overrides the minimumParticleLife and maximumParticleLife inputs with this value.
参数
Sets the minimum bound in seconds for the possible duration of a particle's life above which a particle's actual life will be randomly chosen.
参数
Sets the maximum bound in seconds for the possible duration of a particle's life below which a particle's actual life will be randomly chosen.
参数
Sets the minimum and maximum mass of particles in kilograms.
参数
Sets the minimum bound for the mass of a particle in kilograms. A particle's actual mass will be chosen as a random amount above this value.
参数
Sets the maximum mass of particles in kilograms. A particle's actual mass will be chosen as a random amount below this value.

bursts:
ParticleBurst[]
An array of ParticleBurst, emitting bursts of particles at periodic times.
modelMatrix
modelMatrix:
Matrix4
The 4x4 transformation matrix that transforms the particle system from model to world coordinates.
emitterModelMatrix
emitterModelMatrix:
Matrix4

startColor
startColor:
Color
The color of the particle at the beginning of its life.
endColor
endColor:
Color
The color of the particle at the end of its life.
startScale
startScale:
number
The initial scale to apply to the image of the particle at the beginning of its life.
endScale
endScale:
number
The final scale to apply to the image of the particle at the end of its life.
emissionRate
emissionRate:
number
The number of particles to emit per second.
minimumSpeed
minimumSpeed:
number
Sets the minimum bound in meters per second above which a particle's actual speed will be randomly chosen.
maximumSpeed
maximumSpeed:
number
Sets the maximum bound in meters per second below which a particle's actual speed will be randomly chosen.
minimumParticleLife
minimumParticleLife:
number
Sets the minimum bound in seconds for the possible duration of a particle's life above which a particle's actual life will be randomly chosen.
maximumParticleLife
maximumParticleLife:
number
Sets the maximum bound in seconds for the possible duration of a particle's life below which a particle's actual life will be randomly chosen.
minimumMass
minimumMass:
number
Sets the minimum mass of particles in kilograms.
maximumMass
maximumMass:
number
Sets the maximum mass of particles in kilograms.
minimumImageSize
minimumImageSize:
Cartesian2
Sets the minimum bound, width by height, above which to randomly scale the particle image's dimensions in pixels.
maximumImageSize
maximumImageSize:
Cartesian2
Sets the maximum bound, width by height, below which to randomly scale the particle image's dimensions in pixels.
sizeInMeters
sizeInMeters:
boolean
Gets or sets if the particle size is in meters or pixels. <code>true</code> to size particles in meters; otherwise, the size is in pixels.
lifetime
lifetime:
number
How long the particle system will emit particles, in seconds.
complete
complete:
Event
Fires an event when the particle system has reached the end of its lifetime.
isComplete
isComplete:
boolean
When <code>true</code>, the particle system has reached the end of its lifetime; <code>false</code> otherwise.
方法
isDestroyed()
isDestroyed():
boolean
Returns true if this object was destroyed; otherwise, false. <br /><br /> If this object was destroyed, it should not be used; calling any function other than <code>isDestroyed</code> will result in a DeveloperError exception.
返回
boolean
true if this object was destroyed; otherwise, false.
destroy()
destroy():
void
Destroys the WebGL resources held by this object. Destroying an object allows for deterministic release of WebGL resources, instead of relying on the garbage collector to destroy this object. <br /><br /> Once an object is destroyed, it should not be used; calling any function other than <code>isDestroyed</code> will result in a DeveloperError exception. Therefore, assign the return value (<code>undefined</code>) to the object as done in the example.
返回
void
