constructor

new Merger(effects: (EffectLoop | PrimitiveVec4 | ExprVec4 | Operator<Vec4> | Mutable<PrimitiveVec4> | WrappedExpr<Vec4> | BasicVec4)[] | EffectDictionary, source: WebGLTexture | ImageBitmap | ImageData | HTMLImageElement | HTMLCanvasElement | HTMLVideoElement | OffscreenCanvas, gl: WebGL2RenderingContext, options?: MergerOptions): Merger

- Defined in mergepass.ts:372
constructs the object that runs the effects

Parameters
- effects: (EffectLoop | PrimitiveVec4 | ExprVec4 | Operator<Vec4> | Mutable<PrimitiveVec4> | WrappedExpr<Vec4> | BasicVec4)[] | EffectDictionary
  
  list of effects that define the final effect
- source: WebGLTexture | ImageBitmap | ImageData | HTMLImageElement | HTMLCanvasElement | HTMLVideoElement | OffscreenCanvas
  
  the source image or texture
- gl: WebGL2RenderingContext
  
  the target rendering context
- Optional options: MergerOptions
  
  additional options for the texture
Returns Merger

Methods

changeProgram

changeProgram(str: string): void

- Defined in mergepass.ts:608
changes the current program loop

Parameters
- str: string
  
  key in the program map
Returns void

delete

delete(): void

- Defined in mergepass.ts:571
delete all resources created by construction of this Merger; use right before intentionally losing a reference to this merger object. this is useful if you want to construct another Merger to use new effects

Returns void

draw

draw(timeVal?: number, mouseX?: number, mouseY?: number): void

- Defined in mergepass.ts:521
use the source and channels to draw effect to target context; mouse position (as with all positions) are stored from the bottom left corner as this is how texture data is stored

Parameters
- timeVal: number = 0
  
  number to set the time uniform to (supply this if you plan to use time)
- mouseX: number = 0
  
  the x position of the mouse (supply this if you plan to use mouse or nmouse)
- mouseY: number = 0
  
  the y position of the mouse (supply this if you plan to use mouse or nmouse)
Returns void
