The Lorenz Attractor is the following system of first order ODE:
x ' = a ( y - x )
y ' = x ( b - z ) - y
z ' = xy - cz
( input parameter: a, b, c, T, h, x0, y0, z0 )
Lorenz3d is a real-time 3D visualization of the lorenz attractor,
implemented in c++/openGL - mainly for the purpose of enjoyment. This application
animates the rendering of the lorenz attractor (calculated using forward euler's
method, for any arbitrary set of parameters) in 3-space and offers the following
features:
- arbitrary rotations of the lorenz attractor in real-time
- positioning of the camera at any distance to the attractor.
- render the attractor step by step or in entirity
- roller coaster chase view that flys along the lorenz attractor curve!

lorenz3d usage + keys
|
[L/R] mouse buttons - rotate (normal view only)
| |
's' - reset the tracer to (x0, y0, z0)
| |
'p' - toggle [draw to tracer] or [draw in entirity (t=0:T)]
| |
'v' - toggle [normal] or [roller coaster chase] view
| |
(try different combinations of 's','v','p')
| |
'm' - toggle [line] or [point] mode (normal view only)
| |
'-' - move camera forward (normal view only)
| |
'=' - move camera backward (normal view only)
