Hello,
I tried to use rgl.snapshot and it failed.
The error message was not very verbose:
======================
plot3d( motion[[idx+2]], motion[[idx+1]], motion[[idx]] )
rgl.snapshot(filename="/tmp/shot_01.png", fmt="png")
[1] "failed"
======================
There was a graphic created by rgl, but the snapshot was
not created.
The same problem occurs, when I use
> example(rgl.snapshot)
The graphic/animation will be created, but there is no possibility
to create the output-files.
I use "R version 2.4.0 Patched (2006-11-25 r39997)".
Is this a problem of this old version? or is there
maybe a general problem, independent of the version?
This is a problem with the build. rgl is not easy to build, because it
links to a lot of external libraries. In this case it looks as though
your build (the one from R-forge? You should say...) did not link to
libpng.
