WebGL2RenderingContext: getSamplerParameter() method

The WebGL2RenderingContext.getSamplerParameter() method of the WebGL 2 API returns parameter information of a WebGLSampler object.

Syntax

getSamplerParameter(sampler, pname)

A GLenum specifying which information to return. Possible values:

gl.TEXTURE_COMPARE_FUNC: Returns a GLenum indicating the texture comparison function.
gl.TEXTURE_COMPARE_MODE: Returns a GLenum indicating the texture comparison mode.
gl.TEXTURE_MAG_FILTER: Returns a GLenum indicating the texture magnification filter.
gl.TEXTURE_MAX_LOD: Returns a GLfloat indicating the maximum level-of-detail value.
gl.TEXTURE_MIN_FILTER: Returns a GLenum indicating the texture minification filter
gl.TEXTURE_MIN_LOD: Returns a GLfloat indicating the minimum level-of-detail value.
gl.TEXTURE_WRAP_R: Returns a GLenum indicating the texture wrapping function for the texture coordinate r.
gl.TEXTURE_WRAP_S: Returns a GLenum indicating the texture wrapping function for the texture coordinate s.
gl.TEXTURE_WRAP_T: Returns a GLenum indicating the texture wrapping function for the texture coordinate t.

Depends on the pname parameter, either a GLenum or a GLfloat.

const sampler = gl.createSampler();
gl.getSamplerParameter(sampler, gl.TEXTURE_COMPARE_FUNC);
