Methods

applyFilter(filter, input, output, clear)

core/renderers/webgl/managers/FilterManager.js, line 211

Draws a filter.

Name	Type	Description
filter	PIXI.Filter	The filter to draw.
input	PIXI.RenderTarget	The input render target.
output	PIXI.RenderTarget	The target to output to.
clear	boolean	Should the output be cleared before rendering to it

calculateNormalizedScreenSpaceMatrix(outputMatrix){PIXI.Matrix}

core/renderers/webgl/managers/FilterManager.js, line 457

Multiply vTextureCoord to this matrix to achieve (0,0,1,1) for filterArea

Name	Type	Description
outputMatrix	PIXI.Matrix	The matrix to output to.

Returns:

Type	Description
PIXI.Matrix	The mapped matrix.

calculateScreenSpaceMatrix(outputMatrix){PIXI.Matrix}

core/renderers/webgl/managers/FilterManager.js, line 440

Calculates the mapped matrix.

TODO playing around here.. this is temporary - (will end up in the shader) this returns a matrix that will normalise map filter cords in the filter to screen space

Name	Type	Description
outputMatrix	PIXI.Matrix	the matrix to output to.

Returns:

Type	Description
PIXI.Matrix	The mapped matrix.

calculateSpriteMatrix(outputMatrix, sprite){PIXI.Matrix}

core/renderers/webgl/managers/FilterManager.js, line 476

This will map the filter coord so that a texture can be used based on the transform of a sprite

Name	Type	Description
outputMatrix	PIXI.Matrix	The matrix to output to.
sprite	PIXI.Sprite	The sprite to map to.

Returns:

Type	Description
PIXI.Matrix	The mapped matrix.

destroy()

core/renderers/webgl/managers/FilterManager.js, line 492

Destroys this Filter Manager.

emptyPool()

core/renderers/webgl/managers/FilterManager.js, line 554

Empties the texture pool.

freePotRenderTarget(renderTarget)

core/renderers/webgl/managers/FilterManager.js, line 577

Frees a render target back into the pool.

Name	Type	Description
renderTarget	PIXI.RenderTarget	The renderTarget to free

getRenderTarget(clear, resolution){PIXI.RenderTarget}

core/renderers/webgl/managers/FilterManager.js, line 406

Gets a render target from the pool, or creates a new one.

Name	Type	Description
clear	boolean	Should we clear the render texture when we get it?
resolution	number	The resolution of the target.

Returns:

Type	Description
PIXI.RenderTarget	The new render target

inherited onContextChange()

core/renderers/webgl/managers/WebGLManager.js, line 28

Generic method called when there is a WebGL context change.

popFilter()

core/renderers/webgl/managers/FilterManager.js, line 146

Pops off the filter and applies it.

pushFilter(target, filters)

core/renderers/webgl/managers/FilterManager.js, line 62

Adds a new filter to the manager.

Name	Type	Description
target	PIXI.DisplayObject	The target of the filter to render.
filters	Array.<PIXI.Filter>	The filters to apply.

returnRenderTarget(renderTarget)

core/renderers/webgl/managers/FilterManager.js, line 426

Returns a render target to the pool.

Name	Type	Description
renderTarget	PIXI.RenderTarget	The render target to return.

syncUniforms(shader, filter)

core/renderers/webgl/managers/FilterManager.js, line 287

Uploads the uniforms of the filter.

Name	Type	Description
shader	GLShader	The underlying gl shader.
filter	PIXI.Filter	The filter we are synchronizing.
