Class SolidParticle
Hierarchy
- SolidParticle
Index
Constructors
constructor
Creates a Solid Particle object. Don't create particles manually, use instead the Solid Particle System internal tools like _addParticle()
Parameters
particleIndex: number
(integer) is the particle index in the Solid Particle System pool.
particleId: number
(integer) is the particle identifier. Unless some particles are removed from the SPS, it's the same value than the particle idx.
positionIndex: number
(integer) is the starting index of the particle vertices in the SPS "positions" array.
indiceIndex: number
(integer) is the starting index of the particle indices in the SPS "indices" array.
model: Nullable<ModelShape>
(ModelShape) is a reference to the model shape on what the particle is designed.
shapeId: number
(integer) is the model shape identifier in the SPS.
idxInShape: number
(integer) is the index of the particle in the current model (ex: the 10th box of addShape(box, 30))
sps: SolidParticleSystem
defines the sps it is associated to
Optional modelBoundingInfo: Nullable<BoundingInfo>
is the reference to the model BoundingInfo used for intersection computations.
Optional materialIndex: Nullable<number>
is the particle material identifier (integer) when the MultiMaterials are enabled in the SPS.
Returns SolidParticle
Properties
aliveSearch playground for alive
Is the particle active or not ?
colorSearch playground for color
The color of the particle
culling
The culling strategy to use to check whether the solid particle must be culled or not when using isInFrustum(). The possible values are :
- AbstractMesh.CULLINGSTRATEGY_STANDARD
- AbstractMesh.CULLINGSTRATEGY_BOUNDINGSPHERE_ONLY
- AbstractMesh.CULLINGSTRATEGY_OPTIMISTIC_INCLUSION
- AbstractMesh.CULLINGSTRATEGY_OPTIMISTIC_INCLUSION_THEN_BSPHERE_ONLY The default value for solid particles is AbstractMesh.CULLINGSTRATEGY_BOUNDINGSPHERE_ONLY Please read each static variable documentation in the class AbstractMesh to get details about the culling process.
idSearch playground for id
particle identifier
idxSearch playground for idx
particle global index
idx
Index of the particle in its shape id
is
Is the particle visible or not ?
material
The particle material identifier (integer) when MultiMaterials are enabled in the SPS.
parent
Parent particle Id, if any. Default null.
pivotSearch playground for pivot
The pivot point in the particle local space.
positionSearch playground for position
The world space position of the particle.
propsSearch playground for props
Custom object or properties.
rotationSearch playground for rotation
The world space rotation of the particle. (Not use if rotationQuaternion is set)
rotation
The world space rotation quaternion of the particle.
scalingSearch playground for scaling
The scaling of the particle.
shape
ModelShape id of this particle
translate
Must the particle be translated from its pivot point in its local space ? In this case, the pivot point is set at the origin of the particle local space and the particle is translated. Default : false
uvsSearch playground for uvs
The uvs of the particle.
velocitySearch playground for velocity
The current speed of the particle.
Accessors
has
Returns true if there is already a bounding info
Returns boolean
quaternion
Legacy support, changed quaternion to rotationQuaternion
Returns Nullable<Quaternion>
Legacy support, changed quaternion to rotationQuaternion
Parameters
q: Nullable<Quaternion>
Returns void
scale
Methods
copy
Copies the particle property values into the existing target : position, rotation, scaling, uvs, colors, pivot, parent, visibility, alive
Parameters
target: SolidParticle
the particle target
Returns SolidParticle
the current particle
get
Particle BoundingInfo object
Returns BoundingInfo
a BoundingInfo
intersects
Returns a boolean. True if the particle intersects another particle or another mesh, else false. The intersection is computed on the particle bounding sphere and Axis Aligned Bounding Box (AABB)
Parameters
target: Mesh | SolidParticle
is the object (solid particle or mesh) what the intersection is computed against.
Returns boolean
true if it intersects
is
Returns
trueif the solid particle is within the frustum defined by the passed array of planes. A particle is in the frustum if its bounding box intersects the frustumParameters
frustumPlanes: Plane[]
defines the frustum to test
Returns boolean
true if the particle is in the frustum planes
Represents one particle of a solid particle system.
