WebGLRenderingContext: bindTexture() method

Available in workers

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

Syntax

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. If null is passed, the currently bound texture for the specified target is unbound.

Return value

None (undefined).

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

const canvas = document.getElementById("canvas");
const gl = canvas.getContext("webgl");
const texture = gl.createTexture();

gl.bindTexture(gl.TEXTURE_2D, texture);

Unbinding a texture

// Unbind any texture currently bound to TEXTURE_2D
gl.bindTexture(gl.TEXTURE_2D, null);

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);
