disp3D is a library for 3D application without call opengl function. Writing OpenGL function is time-cosuming and boring. You can display 3D objects very easily as you want with this library.

This library depends on these Gems.

• gmath3D
• ruby-opengl
• rmagick
• qtbindings(optional)

To install it, just type...

$ gem install disp3D

Require 'disp3d', then you can use most of the classes in the lib (except for qt-components).

This is the first code you type.

require 'disp3D'

# create view with GLUTWindow, then set width, height and window title
main_view = Disp3D::GLUTWindow.new(400,400, "01_HelloWorld")

# open world scene graph view has
main_view.world_scene_graph.open do
  # put TeaPod which color is Red and size is 10 
  add_new :type => :TeaPod,
          :material_color => [1,0,0,1],
          :size => 10.0
end

# set parameter for camera
main_view.camera.projection = Disp3D::Camera::ORTHOGONAL

# finally show window!
main_view.start

You can see a teapod is shown in the window. you can rotate it with mouse L button and drag.
