Key Interfaces that will be defined in the Plugin API

• IRenderable
  • void Initialize(...)
  • void Update(...)
  • void Render(...)
  • bool Initialized{get;}
  • bool Disposed{get;}
  • Vector3 Position{get;set;}
  • Vector3 Orientation{get;set;}
  • string Name{get;} //should this be "set" as well?
  • bool Visible{get;set;} //used to be "IsOn", perhaps this shouldn't be "Visible" because being "Visible" doesn't mean that an object is actually in the View Frustum.
  • byte Opacity{get;set;}
  • Hashtable MetaData{get;set;}
  • ArrayList ChildRenderables{get;} //combine RenderableObject and RenderableObjectList

• IInteractive //perhaps there are interfaces in .Net already for this...similar to JAVA KeyListener and MouseListener ?
  • void OnKeyDown(KeyEventArgs e)
  • void OnKeyUp(KeyEventArgs e)
  • void OnMouseDown(MouseEventArgs e)
  • void OnMouseUp(MouseEventArgs e)
  • void OnMouseMove(MouseEventArgs e)
  • void OnMouseWheel(MouseEventArgs e)
  • void OnMouseLeave(EventArgs e)
  • void OnMouseEnter(EventArgs e) //??

• ICamera
  • under construction...
• IWorld
  • under construction...

• AppContext
  • Direct3D.Device Direct3D_Device
  • int ScreenWidth
  • int ScreenHeight
  • ...

One issue that has always bothered me was whether to exclusively make the camera "focus" on a "World" or whether to make it focus on a "RenderableObject". Of course, you cannot really define what a view range is if you focus on something like the International Space Station, but perhaps someone would want to focus on that...
