Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
We don’t know them, we didn’t try them, but you can take a peek.

RGL Video with movi3ed
18 mars 2016, par John1402I am trying to do an animation using the RGL package :
plot3d(x, y,z, xlab="PCA 1", ylab="PCA 2", zlab="PCA 3",
main="MDS PLOT",col=xxx[phenotype$Patient],type="s",radius=0.04)
text3d(x,y,z,as.character(phenotype$contrasts))
movie3d( spin3d(), duration = 10,dir="mds_video",convert=FALSE)The above code is just a Dummy code on the PCA plot I would like to make an animation. However, the png file movie3d generate is highly low resolution. Then I am using ffmpeg to convert the png’s to avi or mp4. However, the png files are really really blurry (Far worse than the pictures in the open gl window). Is there a way to increase the resolution and have a nice animation.
Thanks
