[R] Function movie3d in rgl library resulting in black/blank output

[Manabu Sakamoto]

Dear Duncan,

Thank you for your reply.

I tried rgl.snapshot like this,

    rgl.snapshot("snapshot.png",fmt="png", top=TRUE)

but got a totally black png file. I'm really not sure what this means;
is there something wrong with some software or setting on my computer?

best regards,
Manabu
