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

Debug

In order to simplify troubleshooting, you can use debug modification of DartGL. In this mode, glGetError() is called after each OpenGL. Error message is printed to console if glGetError returns not GL_NO_ERROR.

import 'package:dartgl/debug/dartgl.dart';

To-Do

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

Use this package as a library

1. Depend on it

Add this to your package's pubspec.yaml file:


dependencies:
  dartgl: "^0.1.3"

2. Install it

You can install packages from the command line:

with pub:


$ pub get

Alternatively, your editor might support pub get. Check the docs for your editor to learn more.

3. Import it

Now in your Dart code, you can use:


      import 'package:dartgl/dartgl.dart';
