Methods

activateVao (geometry, program) protected

GeometrySystem.js:359

Activate vertex array object

Name	Type	Description
geometry	PIXI.Geometry	Geometry instance
program	PIXI.Program	Shader program instance

bind (geometry, shader)

GeometrySystem.js:100

Binds geometry so that is can be drawn. Creating a Vao if required

Name	Type	Description
geometry	PIXI.Geometry	instance of geometry to bind
shader	PIXI.Shader	optional instance of shader to use vao for

checkCompatibility (geometry, program) protected

GeometrySystem.js:175

Check compability between a geometry and a program

Name	Type	Description
geometry	PIXI.Geometry	Geometry instance
program	PIXI.Program	Program instance

contextChange ()

GeometrySystem.js:57

Sets up the renderer context and necessary buffers.

destroy () inherited

System.js:25

Generic destroy methods to be overridden by the subclass

disposeAll (contextLost)

GeometrySystem.js:342

dispose all WebGL resources of all managed geometries and buffers

Name	Type	Default	Description
contextLost	boolean	false	optional If context was lost, we suppress gl.delete calls

disposeBuffer (buffer, contextLost)

GeometrySystem.js:284

Disposes buffer

Name	Type	Default	Description
buffer	PIXI.Buffer		buffer with data
contextLost	boolean	false	optional If context was lost, we suppress deleteVertexArray

disposeGeometry (geometry, contextLost)

GeometrySystem.js:305

Disposes geometry

Name	Type	Default	Description
geometry	PIXI.Geometry		Geometry with buffers. Only VAO will be disposed
contextLost	boolean	false	optional If context was lost, we suppress deleteVertexArray

draw (type, size, start, instanceCount)

GeometrySystem.js:404

Draw the geometry

Name	Type	Description
type	Number	the type primitive to render
size	Number	optional the number of elements to be rendered
start	Number	optional Starting index
instanceCount	Number	optional the number of instances of the set of elements to execute

getSignature (geometry, program)String protected

GeometrySystem.js:193

Takes a geometry and program and generates a unique signature for them.

Name	Type	Description
geometry	PIXI.Geometry	to get signature from
program	PIXI.Program	to test geometry against

Returns:

Type	Description
String	Unique signature of the geometry and program

initGeometryVao (geometry, program) protected

GeometrySystem.js:212

Creates or gets Vao with the same structure as the geometry and stores it on the geometry. If vao is created, it is bound automatically.

Name	Type	Description
geometry	PIXI.Geometry	Instance of geometry to to generate Vao for
program	PIXI.Program	Instance of program

reset ()

GeometrySystem.js:132

Reset and unbind any active VAO and geometry

unbind () protected

GeometrySystem.js:440

Unbind/reset everything

updateBuffers () protected
