WebGLRenderingContext.bindTexture()

The WebGLRenderingContext.bindTexture() method of the WebGL API binds a given WebGLTexture to a target (binding point).

Syntax

void gl.bindTexture(target, texture);

Parameters

target
A GLenum specifying the binding point (target). Possible values:
  • gl.TEXTURE_2D: A two-dimensional texture.
  • gl.TEXTURE_CUBE_MAP: A cube-mapped texture.
  • When using a WebGL 2 context, the following values are available additionally:
    • gl.TEXTURE_3D: A three-dimensional texture.
    • gl.TEXTURE_2D_ARRAY: A two-dimensional array texture.
texture
A WebGLTexture object to bind.

Return value

None.

Exceptions

A gl.INVALID_ENUM error is thrown if target is not gl.TEXTURE_2D, gl.TEXTURE_CUBE_MAP, gl.TEXTURE_3D, or gl.TEXTURE_2D_ARRAY.

Examples

Binding a texture

var canvas = document.getElementById('canvas');
var gl = canvas.getContext('webgl');
var texture = gl.createTexture();

gl.bindTexture(gl.TEXTURE_2D, texture);

Getting current bindings

To check the current texture binding, query the gl.TEXTURE_BINDING_2D or gl.TEXTURE_BINDING_CUBE_MAP constants.

gl.getParameter(gl.TEXTURE_BINDING_2D);
