Parameters
sampler-
A
WebGLSamplerobject. pname-
A
GLenumspecifying which information to return. Possible values:gl.TEXTURE_COMPARE_FUNC: Returns aGLenumindicating the texture comparison function.gl.TEXTURE_COMPARE_MODE: Returns aGLenumindicating the texture comparison mode.gl.TEXTURE_MAG_FILTER: Returns aGLenumindicating the texture magnification filter.gl.TEXTURE_MAX_LOD: Returns aGLfloatindicating the maximum level-of-detail value.gl.TEXTURE_MIN_FILTER: Returns aGLenumindicating the texture minification filtergl.TEXTURE_MIN_LOD: Returns aGLfloatindicating the minimum level-of-detail value.gl.TEXTURE_WRAP_R: Returns aGLenumindicating the texture wrapping function for the texture coordinate r.gl.TEXTURE_WRAP_S: Returns aGLenumindicating the texture wrapping function for the texture coordinate s.gl.TEXTURE_WRAP_T: Returns aGLenumindicating the texture wrapping function for the texture coordinate t.
Return value
Depends on the pname parameter, either a GLenum or a
GLfloat.
