Game Overview

• Virul-Glider is a 3D-flight simulator The goal is
  to pilot the glider through a series of courses
  by navigating gates and catching thermals. Avoid
  falling in the water!
• The first level is easy, with no thermals.
  Introduces landing. Upon completion, next level
  loads, which introduces turning. The next level
  contains thermals, and so on The game continues
  until you run out of lives and have to start over.

Viewpoint Controls

• The viewpoint is third person and slightly above
• Pitch and Roll is controlled by the X and Y axis
  of the mouse, but only active when the left mouse
  button is depressed. Yaw stabilization is applied
  to simulate a real aircrafts tail effects.
• Stabilization of Pitch, Yaw, Roll can be
  turned on and off by player at any time,
  depending on players skill level. Degree of
  stabilization and control gain could be varied
  to represent different types of aircraft.
• Up Forward vector 0 and Velocity vector 9
  can be toggled during flight time for training
  purposes. (training/debugging)
• Hitting Boost gives afterburner effect of
  velocity boost in the direction of the forward
  vector. (training/debugging)

Objectives of the Game

• Navigate the course by passing through goals.
  Order doesnt matter.
• Hit thermals to increase vertical height
  Particles!
• Land on the Target at the end of the course after
  passing through all the gates. If you missed a
  gate and land on the finish, then you retry the
  level from the launch point, but the gates are
  not reset and you dont lose a life. Landings
  must be at a slow enough speed and small enough
  angle in order to be considered successful!
• Avoid falling into the water before you reach the
  end of the level.
• Players need to master the dynamics of flight and
  thermals in order to navigate the obstacle
  course. Advanced players can pull off tricks with
  their glider!

Major Solved Risks

• 1. Quaternion imaginary numbers in 3D
• Rotations are pretty simple, dont require
  translations or matrices
• 2. Aerodynamics
• basic flight equations for lift, drag (in
  multiple directions), and gravity.
• Automatic Yaw stabilization is essential for
  realistic flight characteristics.. Just try
  turning it off to see what its like to fly a
  plane without a tail!
• Implemented complex versions of equations which
  allows for later expansion of different types of
  aircraft.
• 3. Collision Detection with Gates Thermals
• Simple closest point on a line - distance between
  path of glider and circle (gates) or cylinder
  (thermals). Gates do have Normal Vectors which
  are utilized for directional gates.
• 4. Camera Follows Glider
• Camera looks between velocity vector and forward
  vector.
• 5. Sky, Water
• Sky is mapped to giant sphere, water mapped to
  giant disk.
• 6. Particle Effects for Thermals
• 250 particles per thermal, only drawn when within
  500 units to conserve processing power.
• 6. Import 3d Model
• Supports different models. Had fun integrating
