Project Progress:

March 28, 2008:
• Compiled and ran a demo in Aszgard

April 13, 2008:
• Compiled and ran an OpenGL camera demo

April 20, 2008:
• Created a Vector3D class that stores a 3-D vector and implements vector arithmetic
• Created a simple Camera class that stores its own position, line of sight, and up vector
• Researched GLUT
• Created a main function that sets up GLUT and, for now, displays a triangle

April 23, 2008:
• Drew a 2-D grid for the game field
• Created a Snake class that represents the Snake
• Implemented a doubly-linked list of SnakeNode objects to represent the Snake's body
• Drew the snake on the game field using GLUT and OpenGL functions
• Fixed overhead camera
• Implemented user input: Arrow keys move snake (in 2-D plane)
• SnakeNodes follow snake head's movement
• New classes:
  • Snake
  • SnakeNode
  • SnakeWorld
  • World
• Not Implemented Yet:
  • Collision detection with walls/self
  • Growing snake size
  • Apples
  • 3-D movement
  • Camera movement

April 24, 2008:
• Collision detection with walls and snake body
• Snake can grow in size correctly (doubly-linked list of SnakeNodes work properly)
• Timer that automatically moves the snake in forward direction every timestep
• Functionality for increasing game speed
• Fixed bug where snake couldn't follow directly behind its tail
• Game ends cleanly before exiting
• Not Implemented Yet:
  • Apples
  • 3-D movement
  • Camera movement

May 1, 2008:
• Added apples to game
• Snake keeps track of apples eaten
• Three sizes of apples that grow the snake a different amount
• Fully functional 2-D game
• Camera Control - can move camera about a sphere (centered at center of game board)
• New Classes:
  • Apple

May 2, 2008:
• Fixed a bug where an apple would not appear
• Game speeds up as player eats more apples
• Camera rotation speed also increases as game speeds up
• Extended the game into 3-D
• Option to draw relevant gridlines
• Walls on same x, y, or z coordinates of snake light up to assist in lining up the snake
• Drew background "box" around the world
• Two control schemes:
  • Absolute: Six movement keys for North, South, East, West, Up (towards the sky), and Down (towards the ground)
  • Snake-Relative: Four movement keys for Up, Down, Right, and Left relative to the snake's current facing and up vector.
• Game records number of apples eaten
• Fully playable 3-D demo

May 5, 2008:
• Drew an "up vector" for the snake's head
• Walls that the snake is adjacent to are big and red
• Fixed a bug with the snake's forward and upward orientation
• Two Camera modes:
  • World View: player controls camera in a sphere around the world
  • Snake View: camera sits in the head of the snake
• Implemented a very rudimentary Snake View camera
• Camera rotates (instead of just jumps) when snake turns
• Implemented turning the camera only to view other sides in snake cam mode
• Toggle between the two camera modes with 'c'
• Fixed a bug when the snake is first created
• Added a three second delay before the snake starts moving when the game begins

May 6, 2008:
• Fixed a bug where using "absolute" controls would mess up "snake-relative" controls
• Improved Snake View camera by putting the camera on top and a little behind the snake's head
• Improved looking around in Snake View mode to be smoother and support diagonal looking

May 7, 2008:
• As speed level increases, more apples appear at once
• Implemented a scoring system
• Draws the player's score to the screen
• After player loses, game restarts by pressing ENTER

May 8, 2008:
• Draws # apples eaten to the screen
• After player loses, displays a Game Over message
• Drew a pair of eyes on the snake head
• Added option to draw the game controls on the bottom right corner of the screen
• Increased the camera rotation speed
• SnakeWorld v1.00 finished!
