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()

in this example, gl must be a WebGL2RenderingContext. WebGLSampler objects are not available in WebGL 1.

const sampler = gl.createSampler();
