Fractint uses the following formula for the henon type: Orbit in two dimensions defined by: x(n+1) = 1 + y(n) - a*x(n)*x(n) y(n+1) = b*x(n) Two parameters: a and b You can find this in the fractint docs. Lots of these mathematicians (Henon, Poincare, etc.) didn't study a single system, they studied families of systems and in many cases multiple families. Its very often the case that any system with non-linear terms (i.e. y^2 or x^2) can exhibit chaotic behavior for some particular set of parameters. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>
