Class: Clouds
A class that generates and manages clouds. Clouds are essentially a 2D grid of cells that contain further sub-grids of
cloud blocks. This 2D grid move altogether in the +x direction, and is generated at the start asynchronously using
web workers using simplex noise.
When using Clouds.update, new clouds will be generated if the center of the grid does not match the passed in position.

Clouds
Constructors
constructor
• new Clouds(options?): Clouds
Create a new Clouds instance, initializing it asynchronously automatically.
Parameters
| Name | Type | Description |
|---|---|---|
options | Partial<CloudsOptions> | Parameters used to create a new Clouds instance. |
Returns
Overrides
Group.constructor
Properties
baseColorHSL
• baseColorHSL: Object
The authored cloud colour, kept because the day/night cycle overwrites the live uniform every frame and would otherwise have nothing to scale from.
Type declaration
| Name | Type |
|---|---|
h | number |
l | number |
s | number |
isInitialized
• isInitialized: boolean = false
Whether or not are the clouds done generating.
locatedCell
• locatedCell: Coords2
The cell that this cloud is currently centered around.
material
• material: ShaderMaterial
The shard shader material used to render the clouds.
meshes
• meshes: Mesh<BufferGeometry<NormalBufferAttributes, BufferGeometryEventMap>, Material | Material[], Object3DEventMap>[][] = []
A 2D array of cloud meshes. The first dimension is the x-axis, and the second dimension is the z-axis.
options
• options: CloudsOptions
Parameters used to create a new Clouds instance.
xOffset
• xOffset: number = 0
The x-offset of the clouds since initialization. This is determined by diffing the locatedCell and the
position passed into Clouds.update.
zOffset
• zOffset: number = 0
The z-offset of the clouds since initialization. This is determined by diffing the locatedCell and the
position passed into Clouds.update.
Methods
dispose
▸ dispose(): void
Returns
void
reset
▸ reset(): Promise<void>
Reset the clouds to their initial state.
Returns
Promise<void>
update
▸ update(position): void
Move the clouds to centering around the passed in position. If there aren't enough cloud cells at any side, new clouds are generated.
Parameters
| Name | Type | Description |
|---|---|---|
position | Vector3 | The new position that this cloud should be centered around. |
Returns
void
