Overview

Copyright 2016 The G3N Authors. All rights reserved. Use of this source code is governed by a BSD-style license that can be found in the LICENSE file.

This file was generated automatically by "glapi2go" and contains all OpenGL constants specified by "#define GL_*" directives contained in "glcorearb.h" for an specific OpenGL version converted to Go constants.

Package gls implements a loader of OpenGL functions for the platform and a Go binding for selected OpenGL functions. The binding maintains some cached state to minimize the number of C function calls. The OpenGL function loader is generated by the "glapi2go" tool by parsing the OpenGL "glcorearb.h" header file

This package also contains abstractions for some OpenGL object such as Program, Uniform, VBO and others.
