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 WebGLSampler interface is part of the WebGL 2 API and stores sampling parameters for WebGLTexture access inside of a shader.
When working with WebGLSampler objects, the following methods of the WebGL2RenderingContext are useful:
WebGL2RenderingContext.createSampler()WebGL2RenderingContext.deleteSampler()WebGL2RenderingContext.isSampler()WebGL2RenderingContext.bindSampler()WebGL2RenderingContext.getSamplerParameter()
Examples
Creating a WebGLSampler object
in this example, gl must be a WebGL2RenderingContext. WebGLSampler objects are not available in WebGL 1.
var sampler = gl.createSampler();

[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.
