Description

Bird Haressment is a graphical implementation of boids, using OpenGL and C++. It simulates the moving patterns of a flock of birds based on the three rules: Seperation, Cohesion and Alignment. A bullet can be shot towards the birds, wheras they will avoid the bullet and break their flying pattern.

Getting Started

Compile and run

Clone the repository and cd into it:

  git clone https://github.com/irvin93d/BirdHaressment.git
  cd BirdHaressment

Create and cd into build folder:

  mkdir build
  cd build

Compile project:

  cmake ..
  make -j4

Run program:

  ./program ../resources

Note that GLM, GLFW and and GLEW variables must be set up for program to run.

Controls

• W/S - Move forward/backwar
• A/D - Strafe left/right
• E/Q - Fly up/down
• LMouse - Shoot
• P - Stop/Run birds
• ESC - Quit

Features Implemented

Required

• Birds shall be built on hierarchical modeling.
• Birds shall move within their own model, such as having wing movement.
• Birds shall use boids to create their moving patterns in a somewhat realistic way.
• Birds shall fly in their own pointing direction, i.e. birds shall not strafe or fly backwards.
• There shall be some way to interrupt the birds’ flying path.
• A sun shall represent the light source.
• Acceleration properties shall be implemented for the moving birds to give them a more realistic speed differentiation.

Recommended

• Environment shall contain hierarchical modelled trees in different sizes.
• Shadows shall exist from all objects, correctly adjusted to sun.
• The sun shall move while time passes by.
• Sky shall be gradient in relationship to the sky.
• Trees shall be growing using fractals as time passes by.

Optional

• Terrain generated by fractals should exist, preferably different on every program start.
• Implement markov chains to give birds and/or different probabilities of their behavior, such as new moving direction for birds and different ways of growing for trees.
• Birds shall “eat” other birds when colliding, causes them to grow. New birds shall appear to keep the number somewhat consistent.
• Blood shall be spilled from cannibalism.

Resources

• Boids example in 2-dimensions, a lot of this source code have been rewritten to C++: Flocking - Processing.org
