GLApp – A tiny wrapper for ruby-opengl

It’s simple:

1. require “glapp”
2. Include GLApp
3. Override as many of the callbacks as you need:
   • setup
   • update(seconds)
   • draw
   • keyboard_down(key, modifiers)
   • keyboard_up(key, modifiers)
   • special_keyboard_down(key, modifiers)
   • special_keyboard_up(key, modifiers)
   • mouse_click(button, state, x, y)
   • mouse_dragging_motion(x, y)
   • mouse_passive_motion(x, y)
4. If you need more control, override the default behavior of these:
   • setup_context
   • pre_draw
   • post_draw
   • resize
5. Call show with width, height, title, and whether to be full-screen

Look at the scripts in the examples/ directory. In fact, here’s one:

require 'glapp'

class MyGame
  include GLApp
  def draw
    glTranslate(0, 0, -5)
    glutSolidCube(2)
  end
end
