• 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

• Update testsuite to use equal and deepEqual. Fix tests that the fix for #219 (732f5ff04b3a285f) broke. The element method now returns true for dependency-mismatch, that’s fine.
