Methods
-
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
-
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
-
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
-
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 (contextLost) overrides
-
Destroys this Filter Manager.
Name Type Default Description contextLost
boolean false optional context was lost, do not free shaders
-
Empties the texture pool.
-
Frees a render target back into the pool.
Name Type Description renderTarget
PIXI.RenderTarget The renderTarget to free
-
getRenderTarget (clear, resolution)PIXI.RenderTarget
-
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 -
onContextChange () inherited
-
Generic method called when there is a WebGL context change.
-
Called before the renderer starts rendering.
-
Pops off the filter and applies it.
-
Adds a new filter to the manager.
Name Type Description target
PIXI.DisplayObject The target of the filter to render.
filters
The filters to apply.
-
Returns a render target to the pool.
Name Type Description renderTarget
PIXI.RenderTarget The render target to return.
-
Uploads the uniforms of the filter.
Name Type Description shader
GLShader The underlying gl shader.
filter
PIXI.Filter The filter we are synchronizing.
