Attrac This software uses innovative techniques to achieve 3-D visualisation of the point sets known as Strange Attractors resulting from iteration of non-linear maps on points in Euclidean Space. Instructions 'm' -> output transform matrix 'p' -> output current point 'f' -> output frames elapsed 'r' -> post redisplay ' ' -> reset transform matrix 'c' -> randomise coefficients 's' -> select next Sprott code from list ESC -> exit 'left mouse button' -> drag mouse to translate in XY plane 'middle mouse button' -> drag mouse to scale 'right mouse button' -> drag mouse to rotate around X and Y axes 25/02/10 Ruben Henner Zilibowitz
