Type Definitions

BufferPositions{Object}

An object holding positions both in an index and a vertex buffer.

Properties:

Name	Type	Description
vertexPosition	number	Position in the vertex buffer
indexPosition	number	Position in the index buffer

Options{Object}

Properties:

Name	Type	Argument	Description
uniforms	Object.<string, module:ol/webgl/Helper~UniformValue>	<optional>	Uniform definitions for the post process steps
postProcesses	Array.<module:ol/renderer/webgl/Layer~PostProcessesOptions>	<optional>	Post-processes definitions

PostProcessesOptions{Object}

Properties:

Name	Type	Argument	Description
scaleRatio	number	<optional>	Scale ratio; if < 1, the post process will render to a texture smaller than the main canvas that will then be sampled up (useful for saving resource on blur steps).
vertexShader	string	<optional>	Vertex shader source
fragmentShader	string	<optional>	Fragment shader source
uniforms	Object.<string, module:ol/webgl/Helper~UniformValue>	<optional>	Uniform definitions for the post process step

WebGLWorkerGenerateBuffersMessage{Object}

This message will trigger the generation of a vertex and an index buffer based on the given render instructions. When the buffers are generated, the worked will send a message of the same type to the main thread, with the generated buffers in it. Note that any addition properties present in the message will be sent back to the main thread.

Properties:

Name	Type	Argument	Description
type	module:ol/renderer/webgl/Layer~WebGLWorkerMessageType		Message type
renderInstructions	ArrayBuffer		Render instructions raw binary buffer.
vertexBuffer	ArrayBuffer	<optional>	Vertices array raw binary buffer (sent by the worker).
indexBuffer	ArrayBuffer	<optional>	Indices array raw binary buffer (sent by the worker).
customAttributesCount	number	<optional>	Amount of custom attributes count in the render instructions.
