Hi, I have found some example of R code : http://commons.wikimedia.org/wiki/File:Mandelbrot_Creation_Animation_%28800x600%29.gif
When I run this code on my computer it takes few seconds. I wanted to make similar program in Maxima CAS : http://thread.gmane.org/gmane.comp.mathematics.maxima.general/29949/focus=29968 for example : f(x,y,n) := block([i:0, c:x+y*%i,ER:4,iMax:n,z:0], while abs(z)<ER and i<iMax do (z:z*z + c,i:i+1), min(ER,abs(z)))$ wxanimate_draw3d( n, 5, enhanced3d=true, user_preamble="set pm3d at b; set view map", xu_grid=70, yv_grid=70, explicit('f(x,y,n), x, -2, 0.7, y, -1.2, 1.2))$ But it takes so long to make even one image ( hours) What makes the difference, and why R so fast ?
