Dadras Strange Attractor
A 3D chaotic attractor with auto-rotation and speed-based coloring
Dadras Attractor: Discovered by Sara Dadras and Hamid Reza Dadras in 2009, this is a 3D autonomous chaotic system defined by ẋ = y − ax + byz, ẏ = cy − xz + z, ż = dxy − ez. For appropriate parameter values, solutions never repeat yet remain bounded — the hallmark of a strange attractor. Chaos here means tiny differences in initial conditions grow exponentially (positive Lyapunov exponent), making long-term prediction impossible. Color encodes instantaneous speed — brighter orange means faster motion through phase space.
