The WebGLRenderingContext.bindBuffer()
method of the WebGL API binds a given WebGLBuffer
to a target.
WebGLRenderingContext.bindBuffer()
Syntax
bindBuffer(target, buffer)
Parameters
- target
-
A
GLenum
specifying the binding point (target). Possible values:-
gl.ARRAY_BUFFER
: Buffer containing vertex attributes, such as vertex coordinates, texture coordinate data, or vertex color data. -
gl.ELEMENT_ARRAY_BUFFER
: Buffer used for element indices. - When using a WebGL 2 context, the following values are available additionally:
-
gl.COPY_READ_BUFFER
: Buffer for copying from one buffer object to another. -
gl.COPY_WRITE_BUFFER
: Buffer for copying from one buffer object to another. -
gl.TRANSFORM_FEEDBACK_BUFFER
: Buffer for transform feedback operations. -
gl.UNIFORM_BUFFER
: Buffer used for storing uniform blocks. -
gl.PIXEL_PACK_BUFFER
: Buffer used for pixel transfer operations. -
gl.PIXEL_UNPACK_BUFFER
: Buffer used for pixel transfer operations.
-
-
- buffer
-
A
WebGLBuffer
to bind.
Return value
None.
Exceptions
Only one target can be bound to a given WebGLBuffer
. An attempt to bind the buffer to another target will throw an INVALID_OPERATION
error and the current buffer binding will remain the same.
A WebGLBuffer
which has been marked for deletion with deleteBuffer
cannot be (re-)bound. An attempt to do so will generate an INVALID_OPERATION
error, and the current binding will remain untouched.
Examples
Binding a buffer to a target
var canvas = document.getElementById('canvas'); var gl = canvas.getContext('webgl'); var buffer = gl.createBuffer(); gl.bindBuffer(gl.ARRAY_BUFFER, buffer);
Getting current bindings
To check the current buffer bindings, query the ARRAY_BUFFER_BINDING
and ELEMENT_ARRAY_BUFFER_BINDING
constants.
gl.getParameter(gl.ARRAY_BUFFER_BINDING); gl.getParameter(gl.ELEMENT_ARRAY_BUFFER_BINDING);
