Dear Duncan, thanks for your prompt reply. I was tempted to use movie3d, but below I copied what I get on my PC. Then, I have ImageMagick installed and, though I set convert equal to FALSE, I was not able to find where the function writes the .png files. Maybe I lack experience in managing such complex functions, but I must confess that I have quite some hard time to grasp info from help(movie3d).
Thanks in advance for any help, Carlo Giovanni > library(rgl) > # set data > f <- function(x,y) { r <- sqrt(x^2+y^2); 10 * sin(r)/r } > x <- seq(-10, 10, length= 30); y <- x > z <- outer(x, y, f) > # set working directory > setwd("U:\\movie") > dir() # check character(0) > # plot > persp3d(x, y, z) > movie3d(spin3d(), duration=5, convert=TRUE) Writing movie000.png [...] Writing movie050.png Error in movie3d(spin3d(), duration = 5, convert = TRUE) : ImageMagick not found > dir() # check again character(0) > movie3d(spin3d(), duration=5, convert=FALSE) Writing movie000.png [...] Writing movie050.png > dir() # check again ?? character(0) > > version _ platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status major 2 minor 8.1 year 2008 month 12 day 22 svn rev 47281 language R version.string R version 2.8.1 (2008-12-22) -----Original Message----- From: Duncan Murdoch [mailto:murd...@stats.uwo.ca] Sent: Wednesday, April 08, 2009 5:13 PM To: Camarda, Carlo Giovanni Cc: r-h...@stat.math.ethz.ch Subject: Re: [R] persp3d and rgl.viewpoint for rotating 3D plots On 4/8/2009 11:01 AM, Camarda, Carlo Giovanni wrote: > Dear R-users, > > within the rgl-package, I would have a question about the usage of > persp3d in combination of rgl.viewpoint. > I am not able to figure out how to let a 3D plot rotating around likewise the > example in ?rgl.viewpoint.
