WebGLBufferWrapper
Wrapper for a WebGL buffer, containing all the information that was used
to create it. This can be a VertexBuffer or IndexBuffer.
A WebGLBuffer should never be exposed outside the WebGLRenderer, so the
WebGLRenderer can handle context loss and other events without other
systems having to be aware of it. Always use WebGLBufferWrapper instead.
Constructor
new WebGLBufferWrapper(gl, initialDataOrSize, bufferType, bufferUsage)
Parameters
| name | type | optional | description |
|---|---|---|---|
| gl | WebGLRenderingContext | No | The WebGLRenderingContext to create the WebGLBuffer for. |
| initialDataOrSize | ArrayBuffer | number | No | Either an ArrayBuffer of data, or the size of the buffer to create. |
| bufferType | GLenum | No | The type of the buffer being created. |
| bufferUsage | GLenum | No | The usage of the buffer being created. gl.DYNAMIC_DRAW, gl.STATIC_DRAW or gl.STREAM_DRAW. |

initialDataOrSize
initialDataOrSize: ArrayBuffer, number
Description:
The initial data or size of the buffer.
Note that this will be used to recreate the buffer if the WebGL context is lost.

webGLBuffer
webGLBuffer: WebGLBuffer
Description:
The WebGLBuffer being wrapped by this class.
This property could change at any time.
Therefore, you should never store a reference to this value.
It should only be passed directly to the WebGL API for drawing.

Public Methods
createResource
<instance> createResource()
Description:
Creates a WebGLBuffer for this WebGLBufferWrapper.
This is called automatically by the constructor. It may also be
called again if the WebGLBuffer needs re-creating.

destroy
<instance> destroy()
Description:
Remove this WebGLBufferWrapper from the GL context.
