2. Project Statement • GlobalFlyer allows a player to fly a Wright brothers-style airplane in 3D space using the OGRE graphic rendering engine and the FMOD sound system.

3. Presentation Outline • Introduction • Review of web page (including goals) • Overview of OGRE • GlobalFlyer software design • Project plan evaluation • Conclusion

5. Overview of OGRE

6. Common Function/Classes in Ogre • root • sceneManager • sceneNode • Entity • Camera/viewPort • light • frameListener • eventProcessor

7. root • Constructor • Root(pluginFileName, configFileName, logFileName) • Some Functions • SceneManager* getCurrentSceneManager(void) • void addFrameListener(FrameListener *) • void startRendering(void) • void shutdown(void) • RenderWindow* initialise(bool, “OGRE Render Window””)

8. sceneManager • Constructor • SceneManager(“[nstance name”) • Some Functions • Camera* createCamera(“name”) • Light* createLight(“name”) • SceneNode* getRootSceneNode(void) • SceneNode* createSceneNode(“name”) • Entity* createEntity(“name”) • void setAmbientLight(ColourValue) • void setWorldGeogmetry(“filename”) • void setSkyPlane(bool, Plane, “materialName”, scale,…) • void showBoundingBoxes(bool) • void setShadowTechnique(ShadowTechnique) • Viewport* getCurrentViewport(void)

9. sceneNode • Constructor • SceneNode(SceneManager, “name”) • Only called by creator SceneManager • Some Functions • void attachObject(MovableObject) • SceneNode* createChildSceneNode(Vector3, Quatrernion) • void setOrientation(w,x,y,z) • void setDirection(x,y,z, TransformSpace, Vector3) • void lookAt(Vector3, TransformSpace, Vector3) • void scale(Vector3) • void addChild(Node*) • void setListener(Listener*)

10. Entity • Inherits from MovableObject • ShadowCaster • AnimableObject • Constructor Entity(“Name”, MeshPtr) • Some Functions • sceneManager _getManager(void) • void setCastShadows(bool) • sceneNode getParentSceneNode(void)

11. Camera/viewPort • Camera(“Name”, SceneManager) • void setPosition(Vector3) • void lookAt(Vector3) • setFocalLength(Real) • Viewport(Camera, RenderTarget, Real…) • RenderTarget* getTarget(void) • Camera* getCamera(void) • void setDimensions(real, real, real, real) • void setBackGroundColour(ColourValue) • void setShadowsEnabled(bool) • void setSkiesEnabled(bool)

12. Light • Inherits from MovableObject • Constructor • Light (“name”) • someMethods • void setType(LightTypes) • Spotlight, Point, Directional • void setDiffuseColour(real, real, real) • void setSpecularColour(real, real, real) • void setAttenuation(real, real, real, real)

13. frameListener • Detailed Description Later • Has 2 public Methods • Bool frameStarted(FrameEvent) • Bool FrameEnded(FrameEvent)

14. eventProcessor • void startProcessingEvents(bool) • bool frameStarted(FrameEvent) • void addEventTarget(EventTarget*) • void addMouseListener(MouseListener*) • void addKeyListener(KeyListener*) • void processKeyEvent(KeyEvent*)

15. Ogre FrameListeners • Not just for kids anymore! • Featuring code examples from • OgreWiki • OgreAPI

16. Root::startRendering • Calls the frameStarted method on all registered FrameListeners • Renders one frame • Calls the frameEnded method on all registered FrameListeners • This continues until one of these methods returns False

17. FrameListener Class • struct FrameEvent • timeSinceLastEvent • timeSinceLastFrame • frameStarted • frameEnded

18. Safety Notice • Ogre chooses the order in which it executes frameStarted and frameEnded • User cannot dictate this order • Nesting FrameListener’s is one way to get around this

19. Example class TutorialFrameListener : public ExampleFrameListener { public: TutorialFrameListener( RenderWindow* win, Camera* cam, SceneManager *sceneMgr )  : ExampleFrameListener(win, cam, false, false) { } bool frameStarted(const FrameEvent &evt) //This function is where you place actions { return ExampleFrameListener::frameStarted( evt ); } bool frameEnded(const FrameEvent &evt) //This function is where you place actions { return ExampleFrameListener::frameEnded( evt ); } protected: bool mMouseDown; // Whether or not the left mouse button was down last frame Real mToggle; // The time left until next toggle Real mRotate; // The rotate constant Real mMove; // The movement constant SceneManager *mSceneMgr; // The current SceneManager SceneNode *mCamNode; // The SceneNode the camera is currently attached to };

20. There Can be only One! • Code can be placed in either: • frameStarted • frameEnded • But, there is only ONE render-cycle per frame • Changes don’t render between frameEnded and frameStarted • So, if frameEnded has a movement that frameStarted negates, the movement will not show

21. Creating a FrameListener • Example: : ExampleFrameListener(win, cam, false, false) //Window, Camera, buffered key input, buffered mouse input • Example: // Create the FrameListener mFrameListener = new TutorialFrameListener(mWindow, mCamera, mSceneMgr); mRoot->addFrameListener(mFrameListener);

22. User Interaction • Arrow keys • Spacebar • F1, F2, F3 • Adding mouse support for camera rotation
