Constructors

constructor

new WaterFlowMaterial(engine, parameters?): WaterFlowMaterial
Parameters
- engine: Engine
- Optional parameters: WaterFlowMaterialParameters
Returns WaterFlowMaterial

Overrides ShaderMaterial.constructor

Properties

alphaHash

alphaHash: boolean

Enables alpha hashed transparency, an alternative to .transparent or .alphaTest. The material will not be rendered if opacity is lower than a random threshold. Randomization introduces some grain or noise, but approximates alpha blending without the associated problems of sorting. Using TAARenderPass can reduce the resulting noise.

alphaToCoverage

alphaToCoverage: boolean

Enables alpha to coverage. Can only be used with MSAA-enabled rendering contexts (meaning when the renderer was created with antialias parameter set to true). Enabling this will smooth aliasing on clip plane edges and alphaTest-clipped edges.

Default

false

blendAlpha

blendAlpha: number

Represents the alpha value of the constant blend color. This property has only an effect when using custom blending with ConstantAlphaFactor or OneMinusConstantAlphaFactor.

Default

blendColor

blendColor: Color

Represent the RGB values of the constant blend color. This property has only an effect when using custom blending with ConstantColorFactor or OneMinusConstantColorFactor.

Default

0x000000

blendDst

blendDst: BlendingDstFactor

Blending destination. It's one of the blending mode constants defined in Three.js. Default is OneMinusSrcAlphaFactor.

Default

THREE.OneMinusSrcAlphaFactor

blendDstAlpha

blendDstAlpha: number

The tranparency of the .blendDst. Default is null.

Default

null

blendEquation

blendEquation: BlendingEquation

Blending equation to use when applying blending. It's one of the constants defined in Three.js. Default is AddEquation.

Default

THREE.AddEquation

blendEquationAlpha

blendEquationAlpha: number

The tranparency of the .blendEquation. Default is null.

Default

null

blendSrc

blendSrc: 200 | 201 | 202 | 203 | 204 | 205 | 206 | 207 | 208 | 209 | 211 | 212 | 213 | 214 | 210

Blending source. It's one of the blending mode constants defined in Three.js. Default is SrcAlphaFactor.

Default

THREE.SrcAlphaFactor

blendSrcAlpha

blendSrcAlpha: number

The tranparency of the .blendSrc. Default is null.

Default

null

blending

blending: Blending

Which blending to use when displaying objects with this material. Default is NormalBlending.

Default

THREE.NormalBlending

clipIntersection

clipIntersection: boolean

Changes the behavior of clipping planes so that only their intersection is clipped, rather than their union. Default is false.

Default

false

clipShadows

clipShadows: boolean

Defines whether to clip shadows according to the clipping planes specified on this material. Default is false.

Default

false

clipping

clipping: boolean

Default

false

clippingPlanes

Default

null

colorWrite

colorWrite: boolean

Whether to render the material's color. This can be used in conjunction with a mesh's .renderOrder property to create invisible objects that occlude other objects. Default is true.

Default

true

defaultAttributeValues

defaultAttributeValues: any

Default

{ 'color': [ 1, 1, 1 ], 'uv': [ 0, 0 ], 'uv1': [ 0, 0 ] }

Default

true

depthWrite

depthWrite: boolean

onBeforeCompile

onBeforeCompile(parameters, renderer): void
An optional callback that is executed immediately before the shader program is compiled. This function is called with the shader source code as a parameter. Useful for the modification of built-in materials, but the recommended approach moving forward is to use WebGPURenderer with the new Node Material system and [TSL]https://github.com/mrdoob/three.js/wiki/Three.js-Shading-Language. Unlike properties, the callback is not supported by .clone(), .copy() and .toJSON(). This callback is only supported in WebGLRenderer (not WebGPURenderer).
Parameters
- parameters: WebGLProgramParametersWithUniforms
  
  WebGL program parameters
- renderer: WebGLRenderer
  
  WebGLRenderer context that is initializing the material
Returns void

Inherited from ShaderMaterial.onBeforeCompile

onBeforeRender

onBeforeRender(renderer, scene, camera, geometry, object, group): void
An optional callback that is executed immediately before the material is used to render a 3D object. Unlike properties, the callback is not supported by .clone(), .copy() and .toJSON(). This callback is only supported in WebGLRenderer (not WebGPURenderer).
Parameters
- renderer: WebGLRenderer
- scene: Scene
- camera: Camera
- geometry: BufferGeometry<NormalBufferAttributes>
- object: Object3D<Object3DEventMap>
- group: Group<Object3DEventMap>
Returns void

Inherited from ShaderMaterial.onBeforeRender

  The type of the listener that gets removed.
