    WebGL2RenderingContext.samplerParameter[if]()

    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.samplerParameter[if]() methods of the WebGL 2 API set WebGLSampler parameters.

    Syntax

    void gl.samplerParameteri(sampler, pname, param);
void gl.samplerParameterf(sampler, pname, param);

    Parameters

    sampler
    A WebGLSampler object.
    pname
    A GLenum specifying which parameter to set. Possible values:
    • gl.TEXTURE_COMPARE_FUNC: A GLenum specifying the texture comparison function.
    • gl.TEXTURE_COMPARE_MODE: A GLenum specifying the texture comparison mode.
    • gl.TEXTURE_MAG_FILTER: A GLenum specifying the texture magnification filter.
    • gl.TEXTURE_MAX_LOD: A GLfloat specifying the maximum level-of-detail value.
    • gl.TEXTURE_MIN_FILTER: A GLenum specifying the texture minification filter
    • gl.TEXTURE_MIN_LOD: A GLfloat specifying the minimum level-of-detail value.
    • gl.TEXTURE_WRAP_R: A GLenum specifying the texture wrapping function for the texture coordinate r.
    • gl.TEXTURE_WRAP_S: A GLenum specifying the texture wrapping function for the texture coordinate s.
    • gl.TEXTURE_WRAP_T: A GLenum specifying the texture wrapping function for the texture coordinate t.
    param
    A GLint (samplerParameteri) or a GLfloat (samplerParameterf) specifying a value for pname.

    Return value

    None.

    Examples

    var sampler = gl.createSampler();
gl.samplerParameteri(sampler, gl.TEXTURE_MAG_FILTER, gl.NEAREST);

    [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.
