Methods

dispose

  • dispose(): void

  • Performs a shallow search for properties that define a dispose method and deletes them.

    The EffectComposer calls this method when it is being destroyed.

    Returns void

getAngle

  • getAngle(): number

  • Returns the pattern angle.

    Returns number

    The angle in radians.

    Deprecated

    Use angle instead.

getAttributes

getBlendMode

  • getBlendMode(): BlendMode

  • Returns the blend mode.

    The result of this effect will be blended with the result of the previous effect using this blend mode.

    Returns BlendMode

    The blend mode.

    Deprecated

    Use blendMode instead.

getDefines

  • getDefines(): Map<string, string>

  • Returns the preprocessor macro definitions.

    Returns Map<string, string>

    The extensions.

    Deprecated

    Use defines instead.

getExtensions

  • getExtensions(): Set<WebGLExtension>

  • Returns the WebGL extensions that are required by this effect.

    Returns Set<WebGLExtension>

    The extensions.

    Deprecated

    Use extensions instead.

getFragmentShader

  • getFragmentShader(): string

  • Returns the fragment shader.

    Returns string

    The fragment shader.

getName

  • getName(): string

  • Returns the name of this effect.

    Returns string

    The name.

    Deprecated

    Use name instead.

getUniforms

  • getUniforms(): Map<string, Uniform<any>>

  • Returns the uniforms of this effect.

    Returns Map<string, Uniform<any>>

    The extensions.

    Deprecated

    Use uniforms instead.

getVertexShader

  • getVertexShader(): string

  • Returns the vertex shader.

    Returns string

    The vertex shader.

initialize

  • initialize(renderer, alpha, frameBufferType): void

  • Performs initialization tasks.

    This method is called when the associated EffectPass is added to an EffectComposer.

    Parameters

    • renderer: WebGLRenderer

      The renderer.

    • alpha: boolean

      Whether the renderer uses the alpha channel or not.

    • frameBufferType: number

      The type of the main frame buffers.

    Returns void

    Example

    if(!alpha && frameBufferType === UnsignedByteType) { this.myRenderTarget.texture.format = RGBFormat; }

setAngle

  • setAngle(value): void

  • Sets the pattern angle.

    Parameters

    • value: number

      The angle in radians.

    Returns void

    Deprecated

    Use angle instead.

Protected setAttributes

  • setAttributes(attributes): void
  • Protected

    Sets the effect attributes.

    Effects that have the same attributes will be executed in the order in which they were registered. Some attributes imply a higher priority.

    Parameters

    Returns void

Protected setChanged

  • setChanged(): void
  • Protected

    Informs the associated EffectPass that this effect requires a shader recompilation.

    Should be called after changing macros or extensions and after adding/removing uniforms.

    Returns void

setDepthTexture

  • setDepthTexture(depthTexture, depthPacking?): void

  • Sets the depth texture.

    You may override this method if your effect requires direct access to the depth texture that is bound to the associated EffectPass.

    Parameters

    • depthTexture: Texture

      A depth texture.

    • Optional depthPacking: DepthPackingStrategies

      The depth packing.

    Returns void

Protected setFragmentShader

  • setFragmentShader(fragmentShader): void
  • Protected

    Sets the fragment shader.

    Parameters

    • fragmentShader: string

      The fragment shader.

    Returns void

setRenderer

  • setRenderer(renderer): void

  • Sets the renderer.

    Parameters

    • renderer: WebGLRenderer

      The renderer.

    Returns void

    Deprecated

setSize

  • setSize(width, height): void

  • Updates the size of this effect.

    You may override this method if you want to be informed about the size of the backbuffer/canvas. This method is called before initialize and every time the size of the EffectComposer changes.

    Parameters

    • width: number

      The width.

    • height: number

      The height.

    Returns void

Protected setVertexShader

  • setVertexShader(vertexShader): void
  • Protected

    Sets the vertex shader.

    Parameters

    • vertexShader: string

      The vertex shader.

    Returns void

update

  • update(renderer, inputBuffer, deltaTime?): void

  • Updates this effect by performing supporting operations.

    This method is called by the EffectPass right before the main fullscreen render operation, even if the blend function is set to SKIP.

    You may override this method if you need to update custom uniforms or render additional off-screen textures.

    Parameters

    • renderer: WebGLRenderer

      The renderer.

    • inputBuffer: WebGLRenderTarget<Texture>

      A frame buffer that contains the result of the previous pass.

    • Optional deltaTime: number

      The time between the last frame and the current one in seconds.

    Returns void
