Two questions related to creating animated movies with rgl:
1. I've created an rgl scene with 5 different views I want to display in
a movie, but I'd like to insert pauses (say, 5 seconds)
at each view. How can I do this?
I first created 5 userMatrix's, then
play3d( par3dinterp( userMatrix=list(M1, M2, M3, M4, M5)),
,duration=2*60/5) )
then tried simply repeating each twice,
play3d( par3dinterp( userMatrix=list(M1, M1, M2, M2, M3, M3, M4, M4, M5,
M5)), ,duration=2*60/5) )
but that didn't give the desired effect. I see that play3d() has a
times= argument, but the documentation
doesn't indicate how to use it in this context.
2. With movie3d(), I can get an animated .gif, but I wonder if there are
other movie formats (.mov, .mpg) I can get,
either with convert, or an external tool, e.g., so I can embed a movie
in a LaTeX -> .pdf document using the
movie15 package.
e.g., I tried using convert at in a command prompt window,
> convert -delay 1x8 coffee-av3D-1*.png coffee-av3D-1.mov
but it seems that only one frame was used.
