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
.
