GAM670/DPS905 -- Weekly Schedule 20121

Week 1 - Jan 8

This Week

  • Assignment Discussion
  • Suggested Enhancements
  • Review of the Base Code
    • Definition of a Framework
      • Modularity through stable interfaces
      • Re-usability through generic components
      • Extensibility through hook methods
      • Inversion of control - determines which application methods to invoke in response to external events
    • Framework Architecture
      • Modelling Layer
      • API Translation Layer
    • Notable Features of the Base Code
    • camera, sound, and light are also derived from the Frame class
    • textures attach at the object level
    • texture connection is uncoupled from drawing of the graphics primitives
    • reference frames are relative
    • very simple collision detection

To Do

  1. add your name to the student list
  2. create a team page that includes the semester number 20121
    • describe the game that you intend to develop
    • list the topics of interest to your team in developing its game
    • list the other topics of interest

Resources

Week 2 - Jan 16

This Week

  • Relative Reference Frames
    • Recursive calls
      Vector Frame::position()
      Matrix Frame::rotation()
      Matrix Frame::world()
    • Detaching from and attaching to a parent frame
      Frame::attachTo()
  • Geometry
    • Plane
      normal + constant - examples
      equation of a plane: dot(n, x) + D = 0
      positive side of a plane dot(n, x) + D > 0
  • Collision Detection
    types of colliders
    spheres
    planes
    axis-aligned bounding boxes
    oriented bounding boxes

To Do

  • Research the feature that you are going to add and prepare a plan of action
  • Prepare a team page for your team so that repos can be ordered
  • Add a section to your team page to track your project and solicit commentary

Resources

      parameter - view * projection
      6 planes
      near and far planes
      left and right planes
      top and bottom planes
      coding
      constructor
      ViewFrustum::contains()

Week 4 - Jan 30

This Week

  • Meshes
    What is a mesh?
    vertex list -> vertex buffer
    index list -> index buffer
    attribute list -> subset to which primitives belong
    pyramid sample
    Stock Objects
    Sphere
    slices and partitions
    Cylinder
    Torus
    Utah Teapot
    APIGraphic.h and .cpp code
    Custom Mesh
    Create a Mesh
    FVF settings
    DrawSubset
    DrawIndexedPrimitive parameters
    APIGraphic.h code
    X File
    Create Mesh from File
  • SkyBox
    definition of a skybox
    attachment to camera
    inverted coordinates
    skybox textures
    Graphic.cpp code
    more complicated forms - skydome
  • Billboards
    definition, purpose of a billboard
    types of billboards
    screen-aligned - useful for annotation text, lens flares
    normal is opposite to camera heading
    up is camera->up
    axial - useful for cylindrical symmetry - trees (textured object does not face straight on)
    up is fixed
    normal faces the viewer as much as possible
    view_plane - no distortion - useful for
    normal is fixed (opposite to camera heading)
    up is open to change
    viewpoint - simulates distortion due to perspective projection - useful for clouds
    normal is fixed (difference between viewpoint position and camera heading)
    up is open to change
    Object.h and Object.cpp code
  • Texture Filtering
    mip maps
    multum in parvo
    texture creation
    APITexture::SetSamplerState()
  • DirectX Errors
    DirectX Utilities - Lookup Tool
    APIDisplay::restore() example

To Do

Resources

Week 5 - Feb 6

This Week

To Do

  • reorganize framework code so that vertex shader receives product of world, view, and projection matrices
    • store viewProjection matrix as an instance variable in Display
    • add viewProjection query to Display to extract product of view and projection matrices
    • retrieve viewProjection in *::draw() method
    • pre-multiply viewProjection by world to obtain composite matrix to pass to vertex shader
    • add composite matrix to the constant table in the vertex shader
  • reorganize framework code to minimize duplication of heading normalization
    • perform normalization of heading in Display::beginDraw()
