WebGLRenderingContext: texParameter[fi]() method
Note: This feature is available in Web Workers.
The WebGLRenderingContext.texParameter[fi]() methods of
the WebGL API set texture parameters.
Syntax

When using a WebGL 2 context, the following values are available additionally:
gl.TEXTURE_3D: A three-dimensional texture.gl.TEXTURE_2D_ARRAY: A two-dimensional array texture.
param-
The
paramparameter is aGLfloatorGLintspecifying the value for the specified parameter pname-
The
pnameparameter is aGLenumspecifying the texture parameter to set.
