⤴️ Algorithms to generate strange attractors such as Lorenz, Burgers, etc.

Strange Attractors
Algorithms to generate strange attractors. Use these algorithms to create Vertex Buffer Objects and Index Buffer Objects for your graphics API of choice.
Usage
Each attractor function returns an array of vertex points in the format [x1, y1, z1, x2, y2, z2, ...], from there you can use the included spline_mesh function to convert that data to a Vertex Buffer and Index Buffer:
from strange_attractors import burgers, spline_mesh
(triangles, vertices, normals) = spline_mesh(burgers(), 4, 0.05)
API
Attractors
Lorenz

from strange_attractors import lorenz
