...and wrapper code generator.

Attention : Version 2 is now available
Though I will continue making this version 1.6 series of opengl-bindings available, please consider migrating to opengl-bindings2.
In version 2, all OpenGL APIs are defined as public methods under module GL
, so we don't have to include OpenGL
and scatter OpenGL APIs under other modules any more:
# opengl-bindings
require 'opengl'
include OpenGL
# ...
glEnable(GL_DEPTH_TEST)
↓
# opengl-bindings2
require 'opengl'
# ...
GL.Enable(GL::DEPTH_TEST)
All redundant nil
checks done on every API calls are removed in version 2:
# opengl-bindings1
module OpenGL
#...
def self.get_command( sym )
if GL_FUNCTIONS_MAP[sym] == nil
bind_command( sym )
end
return GL_FUNCTIONS_MAP[sym]
end
#...
def glEnable(_cap_)
f = OpenGL::get_command(:glEnable) # Every API call caused redundant nil check here
f.call(_cap_)
end
↓
# opengl-bindings2
module GL
#...
def self.Enable(_cap_)
GL_FUNCTIONS_MAP[:glEnable].call(_cap_) # Hashmap is built on initialization so there's no need to do nil check at every API call
end
-
Uses Fiddle (One of the Ruby standard libraries that wraps libffi)
- Unlike opengl ( https://rubygems.org/gems/opengl ), you don't need to build C extension library
-
Uses Khronos XML API registry ( https://github.com/KhronosGroup/OpenGL-Registry )
- The command/enum wrapper codes are generated via 'gl.xml'
- Supports OpenGL - 4.6, OpenGL ES - 3.1 and all OpenGL extensions.
Via RubyGems ( https://rubygems.org/gems/opengl-bindings2 ):
$ gem install opengl-bindings2
Or grab all library codes (`lib/*.rb') and use them by adding as one of the load paths like:
$ ruby -I ./lib your_app.rb
See sample/simple.rb or sample/simple_glut.rb.
To get more samples and generator scripts, please visit: https://github.com/vaiorabbit/ruby-opengl
-
'opengl.rb' includes these scripts:
- 'opengl_command.rb' : OpenGL command wrapper (glDrawRangeElements, etc.). Generated via generator/generate_command.rb.
- 'opengl_enum.rb' : OpenGL enum wrapper (GL_TRIANGLE_STRIP, etc.). Generated via generator/generate_enum.rb.
- 'opengl_common.rb' : Provides utility functions.
- 'opengl_platform.rb' : Provides platform check functions (OpneGL.get_platform).
- 'opengl_windows.rb' : Provides functions for Windows platform (wglGetProcAddress, wglGetCurrentContext, wglGetCurrentDC).
- 'opengl_macosx.rb' : Provides functions for Mac OS X platform (CGLGetCurrentContext, CGLGetShareGroup).
- 'opengl_linux.rb' : Provides functions for Linux (X Window) platform (glXGetCurrentContext, glXGetCurrentDisplay).
-
'opengl_es.rb' is almost the same with 'opengl.rb', except for including 'opengl_es_command.rb' and 'opengl_es_enum.rb'.
-
'opengl_ext.rb' includes these scripts:
- 'opengl_ext_command.rb' : OpenGL extension command wrapper. Generated via generator/generate_ext_command.rb.
- 'opengl_ext_enum.rb' : OpenGL extension enum wrapper Generated via generator/generate_ext_enum.rb.
- 'opengl_ext_common.rb' : Provides utility functions.
-
'opengl_es_ext.rb' is almost the same with 'opengl_ext.rb', except for including 'opengl_es_ext_command.rb' and 'opengl_es_ext_enum.rb'.
-
'glfw.rb'
- My handwritten GLFW wrapper.
-
'glut.rb'
- GLUT wrapper. Supports API Level 4 (GLUT_API_VERSION = 4).
-
'glu.rb'
- My handwritten GLU wrapper.
-
'generator/gl.xml'
- Khronos' official XML API registry for OpenGL.
-
'generator/Rakefile'
- Type 'rake' to generate wrapper codes / fetch gl.xml.
- You can get the latest one by 'get_gl_xml.rb'.
-
'sample/simple.rb', 'sample/simple_glut.rb'
- Simple example.
- simple.rb : You need to get glfw3.dll (Windows) or libglfw.dylib (Mac OS X). See sample/README.md.
- simple_glut.rb : (For Windows uses) You need to get freeglut.dll. See sample/README.md.
-
'sample/data', 'sample/util'
- Data and utilities for sample programs.
- Fiddle
- A libffi wrapper
- Standard library since Ruby 2.0.0
- I recommend you to use Ruby 2.1.2 and later, which fixed Fiddle's memory leak issue (https://bugs.ruby-lang.org/issues/9599).
Use GLFW or GLUT for creating windows and OpenGL rendering contexts.

GLuint tex_names_buf[2]; glGenTextures( 2, tex_names_buf ); GLuint tex_name = tex_names_buf[0];
-
(This library)
tex_names_buf = ' ' * 8 # String instance that is enough to catch texture names (integer). glGenTextures( 2, tex_names_buf ) tex_name = tex_names_buf.unpack('L2')[0]
-
(ruby-opengl2)
tex_name = glGenTextures( 2 )[0]

Version 2 が利用可能です
Version 1.6 系の opengl-bindings も引き続き利用できるようにしますが、opengl-bindings2 への移行を検討してください。
Version 2 では OpenGL API が module GL
の public メソッドとして定義され、include OpenGL
を実行する必要がなくなりました。
# opengl-bindings
require 'opengl'
include OpenGL
# ...
glEnable(GL_DEPTH_TEST)
↓
# opengl-bindings2
require 'opengl'
# ...
GL.Enable(GL::DEPTH_TEST)
API を呼ぶたびに走っていた無駄な nil
のチェックが Version 2 では削除されています。
# opengl-bindings1
module OpenGL
#...
def self.get_command( sym )
if GL_FUNCTIONS_MAP[sym] == nil
bind_command( sym )
end
return GL_FUNCTIONS_MAP[sym]
end
#...
def glEnable(_cap_)
f = OpenGL::get_command(:glEnable) # Every API call caused redundant nil check here
f.call(_cap_)
end
↓
# opengl-bindings2
module GL
#...
def self.Enable(_cap_)
GL_FUNCTIONS_MAP[:glEnable].call(_cap_) # Hashmap is built on initialization so there's no need to do nil check at every API call
end
- 標準ライブラリ Fiddle を使っています ⇒ opengl ( https://rubygems.org/gems/opengl ) のように拡張ライブラリをビルドする必要がありません
- 関数とenumのラッパーコードは Khronos の XML API registry ( https://github.com/KhronosGroup/OpenGL-Registry ) の gl.xml から自動生成しています
RubyGems経由で ( https://rubygems.org/gems/opengl-bindings2 ):
$ gem install opengl-bindings2
もしくは lib 以下の *.rb をコピー → その場所をロードパスに加えて次のように起動:
$ ruby -I ./lib your_app.rb
sample/simple.rb または sample/simple_glut.rb を参照してください。
その他のサンプルと自動生成スクリプトはこちらで開発しています: https://github.com/vaiorabbit/ruby-opengl
-
'opengl.rb' を require することで下記のスクリプトを取り込みます:
- 'opengl_command.rb' : OpenGL 関数のラッパーコード (glDrawRangeElements, etc.)。 generator/generate_command.rb で自動生成されたものです。
- 'opengl_enum.rb' : OpenGL enum のラッパーコード (GL_TRIANGLE_STRIP, etc.)。 generator/generate_enum.rb で自動生成されたものです。
- 'opengl_common.rb' : 共通のユーティリティ関数を提供しています。
- 'opengl_platform.rb' : 動作プラットフォームの判別機能を提供しています (OpneGL.get_platform)。
- 'opengl_windows.rb' : Windows 用の機能を提供しています (wglGetProcAddress, wglGetCurrentContext, wglGetCurrentDC).
- 'opengl_macosx.rb' : Mac OS X 用の機能を提供しています (CGLGetCurrentContext, CGLGetShareGroup).
- 'opengl_linux.rb' : Linux (X Window) 用の機能を提供しています (glXGetCurrentContext, glXGetCurrentDisplay).
-
'opengl_es.rb' は 'opengl_es_command.rb' と 'opengl_es_enum.rb' を取り込む以外は 'opengl.rb' と同じです。
-
'opengl_ext.rb' を require することで下記のスクリプトを取り込みます:
- 'opengl_ext_command.rb' : OpenGL 拡張関数のラッパーコード。 generator/generate_ext_command.rb で自動生成されたものです。
- 'opengl_ext_enum.rb' : OpenGL 拡張enumのラッパーコード。 generator/generate_ext_enum.rb で自動生成されたものです。
-
'opengl_es_ext.rb' は 'opengl_es_ext_command.rb' と 'opengl_es_ext_enum.rb' を取り込む以外は 'opengl_ext.rb' と同じです。
-
'glfw.rb'
- GLFW のラッパーコードです(自動生成ではありません)。
-
'glut.rb'
- GLUT ラッパー。API Level 4 までサポートしています (GLUT_API_VERSION = 4)。
-
'glu.rb'
- GLU のラッパーコードです(自動生成ではありません)。
-
'generator/gl.xml'
- Khronos 公式の XML API registry です。
-
'generator/Rakefile'
- 自動生成関連のタスクを自動化するためのものです。'rake' と打てば gl.xml の取得とラッパーコードの生成を実行します。
- gl.xml の取得だけなど、単体のタスクなら 'get_gl_xml.rb' などの個別Rubyスクリプトでも実行できます。
-
'sample/simple.rb', 'sample/simple_glut.rb'
- 一番簡単なサンプルです。
- simple.rb : 同じ場所に glfw3.dll (Windows) もしくは libglfw.dylib (Mac OS X) を置いてください。詳細は sample/README.md に記載されています。
- simple_glut.rb : (Windows の場合) freeglut.dll を置いてください。詳細は sample/README.md に記載されています。
-
'sample/data', 'sample/util'
- サンプルで共有する機能・データの配置場所です。
- Fiddle
- libffi のラッパーです
- Ruby 2.0.0 以降で標準ライブラリになりました
- Fiddle のメモリリーク問題 (https://bugs.ruby-lang.org/issues/9599) が修正された Ruby 2.1.2 以降での利用を推奨します
GLFW か GLUT を用意してください。ウィンドウやレンダリングコンテキストの管理に必要です。

Rubyスタイルの便利なインターフェースはサポートしていません (ruby-opengl2 ( http://ruby-opengl.rubyforge.org/ ) にあったような感じのもの)
- 例:
-
(OpenGLオリジナルの C API)
GLuint tex_names_buf[2]; glGenTextures( 2, tex_names_buf ); GLuint tex_name = tex_names_buf[0];
-
(このライブラリの場合)
tex_names_buf = ' ' * 8 # テクスチャ名(GLuint)を受け取るのに十分なサイズ String インスタンスであればOK glGenTextures( 2, tex_names_buf ) tex_name = tex_names_buf.unpack('L2')[0]
-
(ruby-opengl2 の場合)
tex_name = glGenTextures( 2 )[0] # glGenTextures が配列を返すように修正されています
