  • RGL Video with movi3ed

    18 mars 2016, par John1402

    I 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
