Dynamical Systems

A C program for visualizing continuous time dynamical systems in a 3D space.

Features

• 3D plotting
• customizable input equations
• mouse and keyboard controls for the 3D plot

Installation

Dependencies

• cglm
• freetype
• gmp
• GLEW
• GLFW3
• OpenGL
• lizard
• ds

With Nix

nix build

With Make

make

Usage

./dynsys

Controls

• w,a,s,d: camera angle
• -,=: zoom
• z: toggle cross
• x: toggle axis
• c: clear/reset
• spacebar: pause/resume
• m,,: speed decrease
• .,/: speed increase
• j,l: x translation
• i,k: y translation
• p,;: z translation
• v, b: dt

Note: at the moment the input equation must be provided in Polish notation:

Lorenz attractor:
dx: ( * 10 (- y x))
dy: ( - (* x (- 28 z)) y)
dz: ( - (* x y) (* (/ 8 3) z))

Rössler attractor:
dx: ( - 0 ( + y z))
dy: ( + x ( * (/ 1 5) y))
dz: ( + (/ 1 5) ( * z ( - x (/ 57 10))))
