export screenshot

Description

Saves the screenshot as png file.

Usage

rgl.snapshot( filename, fmt = "png", top = TRUE )
snapshot3d( ... )

Arguments

Details

Animations can be created in a loop modifying the scene and saving each screenshot to a file. Various graphics programs (e.g. ImageMagick) can put these together into a single animation. (See movie3d or the example below.)

Note

On some systems, the snapshot will include content from other windows if they cover the active rgl window. Setting top = TRUE (the default) will use rgl.bringtotop before the snapshot to avoid this.

Examples

## Not run: 

#
# create animation
#

shade3d(oh3d(), color = "red")
rgl.bringtotop()
rgl.viewpoint(0, 20)

olddir <- setwd(tempdir())
for (i in 1:45) {
  rgl.viewpoint(i, 20)
  filename <- paste("pic", formatC(i, digits = 1, flag = "0"), ".png", sep = "")
  rgl.snapshot(filename)
}
## Now run ImageMagick in tempdir().  Use 'convert' instead of 'magick'
## if you have an older version of ImageMagick:
##    magick -delay 10 *.png -loop 0 pic.gif
setwd(olddir)

## End(Not run)
