The WebGLRenderingContext.bindBuffer() method of the WebGL API binds a given WebGLBuffer to a target.
WebGLRenderingContext: bindBuffer() method
Syntax
js
bindBuffer(target, buffer)
Parameters
-
target -
A
GLenumspecifying 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
WebGLBufferto bind.
Return value
None (undefined).
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
js
const canvas = document.getElementById("canvas");
const gl = canvas.getContext("webgl");
const 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.
js
gl.getParameter(gl.ARRAY_BUFFER_BINDING);
gl.getParameter(gl.ELEMENT_ARRAY_BUFFER_BINDING);
