    WebGL2RenderingContext.vertexAttribDivisor()

    This is an experimental technology
    Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

    The WebGL2RenderingContext.vertexAttribDivisor() method of the WebGL 2 API modifies the rate at which generic vertex attributes advance when rendering multiple instances of primitives with gl.drawArraysInstanced() and gl.drawElementsInstanced().

    Note: When using WebGL 1, the ANGLE_instanced_arrays extension can provide this method, too.

    Syntax

    void gl.vertexAttribDivisor(index, divisor);

    Parameters

    index
    A GLuint specifying the index of the generic vertex attributes.
    divisor
    A GLuint specifying the number of instances that will pass between updates of the generic attribute.

    Return value

    None.

    Examples

    gl.vertexAttribDivisor(0, 2);

    [1] WebGL 2 is enabled by default in Firefox Nightly. To enable it in a release version of Firefox, set the preference webgl.enable-prototype-webgl2 to true in about:config.

    [2] To use an experimental implementation of WebGL 2 in Chrome, you have to start Chrome with the runtime flag --enable-unsafe-es3-apis.
