dartgl 0.1.2

You can easily call native OpenGL functions from Dart. OpenGL 4.5 core profile and ARB extension interfaces are supported.

DartGL

It is a native extension for Dart to use OpenGL in desktop applications. On www.dartlang.org they call it "command-line or server applications". However, you can definitely create GUI application and use OpenGL too.

Support matrix

• OpenGL: 3.3-4.5 core profile
• OS: Linux 64-bit and Windows 32|64-bit
• Dart: any

How to install

• Add to pubspec.yaml

dependencis:
  dartgl: 

• Run

pub get

How to use

• Add to your Dart file

import 'package:dartgl/dartgl.dart';

• Create OpenGL context (see Notes)
• Just use OpenGL functions and constants

  var vertexShader = glCreateShader(GL_VERTEX_SHADER);
  var fragmentShader = glCreateShader(GL_FRAGMENT_SHADER);
  ...
  
  var program = glCreateProgram();
  glAttachShader(program, vertexShader);
  glAttachShader(program, fragmentShader);
  
  glBindAttribLocation(program, 0, "in_Position");
  glBindAttribLocation(program, 1, "in_Color");
  glBindAttribLocation(program, 2, "in_Texture");
  
  glLinkProgram(program);
  location = glGetUniformLocation(program, "in_Time");
    
  var arrays = new Uint32List(1);
  glGenVertexArrays(1, arrays);
  ...
  
  while (...){

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);  
    ...
    /.
}

Notes

For testing purpose, I created native extension for a tiny part of SDL 2.0 to create a window, create OpenGL context and manage window events. You can use your own way.

Examples

In order to run basic examples from test directory, SDL should be installed.

• Linux

sudo apt-get install libsdl2-2.0

• Windows

Download and add to PATH

To-Do

• Improve performance
• Improve tests
• MacOS X support
• OpenGL ES support
