  10. Systems:: WAVE • WAVE (Jet Integrated Virtual Environment) Keng Shih-Ling

  11. Systems:: JIVE • JIVE (Wide Area Virtual Environment) Keng Shih-Ling

  12. Jet Systems • Kernel • Input • Interface • Network • Render • Sound • Artificial Intelligence • WAVE (Wide Area Virtual Environment) • JIVE (Jet Integrated Visual Environment) Keng Shih-Ling

  13. System:: Kernel • The Jet Kernel is the hub of all other Jet systems and provides support for some of Jet’s key features such as: • OS abstraction • Win32 (Linux) • Low-level services • Language extensions • Memory management • Multi-threading support • Debugging facilities Keng Shih-Ling

  14. System:: Kernel • Major Systems: • Jet Task Management System • Jet Resource System • Jet Plug-in System Keng Shih-Ling

  15. System::Kernel:: Task • Jet Task Management System • Tasks provide Jet's main frame-level update mechanism. Each task is called once-per-frame and may be suspended or resumed individually. • The Task Manager is responsible for initializing, updating, and uninitializing tasks. Tasks are added to the Task Manager and stored in a prioritized list in order from highest priority at the top of the list to lowest at the bottom. Keng Shih-Ling

  16. System::Kernel:: Task • Jet system tasks and their priority Keng Shih-Ling

  17. System::Kernel:: Task • Main thread Keng Shih-Ling

  18. System::Kernel:: Task • Jet is a multi-threads system • The main thread • The network thread • The sound streaming thread • The resource streaming thread Keng Shih-Ling

  19. System::Kernel:: Resource • Jet Resource Management System • Resource Databases • A tree-like structure • Resource & Resource types • Each resource type is handled by a specific resource plug-in • (*.bmp, *.jpg, *.pm, *.im, *.kin, *.mp3, …) • Resource aliases • (*.bmp.alias, *.pm.alias, *.mp3.alias, …) Keng Shih-Ling

  20. System::Kernel:: Resource • Jet Resource Management System • Asynchronous background loading • Use multi-threading abilities • Allows the application to continue its execution while resources are being loaded. • Resource priority • Load critical resources ahead of less critical ones. Keng Shih-Ling

  21. System::Kernel:: Plug-in • Jet Plug-in Management System • Jet's Plug-in Management System allows programmers to add, replace and/or extend engine features and systems • Winamp • 3dsMax Keng Shih-Ling

  22. System::Kernel:: Plug-in • Jet Plug-in Management System • Encapsulated user interface components • Different resource loading schemes • Hardware and third-party API device drivers • JIVE plug-in tools and applications Keng Shih-Ling

  23. Jet Systems • Kernel • Input • Interface • Network • Render • Sound • Artificial Intelligence • WAVE (Wide Area Virtual Environment) • JIVE (Jet Integrated Visual Environment) Keng Shih-Ling

  24. System:: Render • Render system DLL Hierarchy Keng Shih-Ling

  25. System:: Render • DLLs and sample functionality Keng Shih-Ling

  26. System:: Render • Rendering Pipeline Keng Shih-Ling

  27. System:: Render • Kernel • Graphics API Abstraction • Rendering Optimization Support • Layers • Scene Support • Modifiers • Animation Support • Progressive LOD Support • Mesh Support • Sprite support • Particle Effects System • Texture And Material Support Keng Shih-Ling

  28. System::Render:: Kernel • Kernel • RenderKernel • The RenderKernel initializes and provides an interface to the Render system ( SceneGraph, MaterialManager, TextureManager…) • SystemResourceViewer • SystemResourceViewer allows derived classes to receive a Layer visible list before each frame is rendered Keng Shih-Ling

  29. System::Render:: API • Graphics API Abstraction • Vertex Formats • PackedVertex{P,N,C,W,T,TT} • GeometryChunk • a base class describing geometry grouped for efficient rendering. Keng Shih-Ling

  30. System::Render:: Optimization • Rendering Optimization Support • The core of Jet's rendering optimization support are render caches • RenderingCache • Alpha, Materials, Shadows, Particle effects • RenderingCacheManager • RenderingCache objects receive a priority used by the RenderingCacheManager to control sequencing. Keng Shih-Ling

  31. System::Render:: Layers • Layers • A Layer is a rendering abstraction representing a rectangular screen region, with a separate rendering pass within the current frame • Viewport • Canvas Keng Shih-Ling

  32. System::Render:: Scene • Scene Support • The Jet Render System supports many types of scene abstractions, such as: • 3D object hierarchies • Lights • Shadows • 2D/3D primitives (also used for collision checking) Keng Shih-Ling

  33. System::Render:: Scene • Scene Support • SceneGraph • Element and VisibleElement • Particle (for 3D object hierarchy) • Line2D, Cone, Polygon (2D/3D primitives) • Lights • LightTargets • Shadows • ShadowVolume Keng Shih-Ling

  34. System::Render:: Modifiers • Modifiers • Jet provides custom update mechanisms through the Modifier and its associated classes • Modifier • ModifierHost • ModifierList Keng Shih-Ling

  35. System::Render:: LOD • Progressive LOD support • Jet’s progressive level-of-detail (LOD) supports scene-balancing through scalable LOD scene objects and manager. The manager distributes geometry to each scalable object to meet the scene’s target geometry allowance. Keng Shih-Ling

  36. System::Render:: LOD • Progressive LOD support • ScalableDetail • ScalableDetailManager • ScalableDetailManager uses the object’s distance from the camera and size to allocate triangles Keng Shih-Ling

  37. System::Render:: Mesh • Mesh Support • Geometry, TriangleGeometry • FaceDescriptor • to query a mesh for information regarding a given face • IndexedMeshInstance • ProgressiveMeshInstance Keng Shih-Ling

  38. System::Render:: Mesh • Mesh Support • InfluenceMesh • provides skin deformation for Jet mesh objects • MeshObservers • allows derived classes to receive mesh related events and define actions on a per-event basis. Keng Shih-Ling

  39. System::Render:: Animation • Animation Support • Skeleton, SkeletonModifier • AnimationModifier • Animator • AnimaitonObserver • AnimationEvent Keng Shih-Ling

  40. System::Render:: Sprite • Sprite Support • SpriteInstance • SpriteManager • SpriteResource Keng Shih-Ling

  41. System::Render:: Particle • Particle Effect System • ParticleFXEmitter • Point, Ribbon, Disc, Rect • ParticleFXModifier • Color, Field, Swirl Keng Shih-Ling

  42. System::Render:: Texture & Material • Texture & Material Support • Texture • TextureManager • The TextureManager controls the creation, activation, and updating of textures used per frame. • Material • MaterialManager Keng Shih-Ling
