AGE is a 3D software development kit for Windows for developing graphicals applications with multithread support built on top of the OpenGL or Direct3D API. It offers automatic resource management, a scene graph support and an highly configurable 3D GUI. The new UI Editor alpha v0.0.1 lets design and build widgets and windows using on-screen forms using the same widgets that will be used in your AGE application.
