This are the functions that are getting called in the beginning of Moviesandbox.

[edit] Program Start

• construct an intermediate window and check for OpenGL versions and Extensions.
• destroy intermediate Window
• create either an X1600Renderer Object (for OpenGL 2.0) or a regular Renderer Object(for OpenGL 2.1)

• construct an Input Object
• call Renderer -> loadPreferences()
  • opens config.xml file
  • loads rendering preferences from xml file (such as window size, multisampling, etc...
  • fills library vector with all libraries found in xml file
  • sets up my.library if not already existing

• call Renderer -> initWindow()
  • creates Moviesandbox OpenGL context and window

• call Renderer -> setup()
  • setup ODE Physics
  • build Object Tables for RTTI and Serialization
  • create Base Layer FBO
  • add Brush
  • add Grid
  • calls Input->setup
    • creates new InspectorManager
    • creates new Controller
    • calls Controller->setup()
      • creates all Tools
      • setup all Tools
      • set current Tool to STATE_SELECT
      • change filter on second draw Tool to Calligraphy Filter
    • clears FPS Buffer
  • creates new Content Class (which is used for interface setup)
  • calls Content->setup
  • calls Input->getAllPrefabs
  • cycles through and libraries
  • calls Input->loadMeshes with current library
  • calls Input->loadTextures with current library
  • calls Input->loadShaders with current library
  • calls Input->loadActionList with current library
  • calls Input->loadAll with startSceneFileName from config.xml (loads scene contents)
    • calls InspectorManager->setup()
  • checks for multisdample capabilities
  • generates picking Texture
  • creates Main Rendering FBO (multisampleBuffer)
  • creates Lighting FBO (lighting)
  • creates Shadow FBO (shadow)
• start Loop

[edit] Main Loop

• calls Renderer->update
  • all Nodes get updated
  • all NodeIOs get updated
  • all Buttons get updated 'this happens again in Input!'
  • all Actors get assigned an ActorID (int that gives their location in ActorList)
  • all Actors get updated
  • all helpers get updated
  • calls Input->update
    • hudTarget is set NULL
    • worldTarget is set NULL
    • staticButton is updated (if not NULL) and set to focusButton
    • Buttons get updated (if bAlwaysUpdate) 'this happened before in Renderer!'
    • Buttons not Hidden get checked for mouseOver and assigned to hudTarget if mouseOver and their Button->mouseOver function called
    • ActorMenu (if exists) gets updated
    • Controller gets updated
      • current Tool gets updated
      • eventTriggers get transferred from input->eventTrigger to control->eventTrigger
      • input->eventTrigger get cleared
      • Nodes get updated if we're running the simulation
      • eventTrigger gets cleared
      • calls navTool->processMove()
    • lastKey gets set to 0
    • increment mouse Button counters if appropriate
    • 0 out mouseVector
  • calls PhysicsUpdate if updating physics is enabled
  • calls draw() on windows or glutPostRedisplay() on MacOS
