Hi!
For saving 3d plots I make use of the "rgl.snapshot" command provided within
the rgl-Package. So far there was no problem using Windows XP, but under
Windows 7 the result is a black image, however in the png-format (see
attachment http://r.789695.n4.nabble.com/file/n2844487/Koll_perf.png ).
What can I do? (Reinstalling Windows XP is no alternative. :-) )
You don't give any code to reproduce what you did, but the following
just worked for me on Windows 7:
example(plot3d)
rgl.snapshot("c:/temp/test.png")
The usual reasons rgl.snapshot fails are these:
- Bugs in your graphics card or its driver. Try updating the driver.
- The rgl graphics window being hidden at the time you call
rgl.snapshot(). Some graphics drivers don't update the buffer if it's
not visible, so rgl.snapshot() grabs junk.
If you have the problem with my two lines above and neither suggestion
above fixes it, then I don't know what's going on, and I wouldn't be
very optimistic you'll be able to fix it.
