While running the example code on the VCS 3D Animation Tutorial (https://cdat.llnl.gov/Jupyter-notebooks/vcs/Animations/Animations.html), Example 3: Rotating Globe, the animation that is created is not right. A red square in the attached screenshot highlights what seems to be a portion of the globe in the lower left corner of the window. Previously, the globe was centered in the middle of the view.
The code I used to create the animation is the following (updated to Python 3 from the Python 2 code in the example on the Tutorial page listed above - Python 2 code commented out):
import requests
r = requests.get("https://uvcdat.llnl.gov/cdat/sample_data/clt.nc",stream=True)
with open("clt.nc","wb") as f:
for chunk in r.iter_content(chunk_size=1024):
if chunk: # filter local_filename keep-alive new chunks
f.write(chunk)
import cdms2
f=cdms2.open("clt.nc")
clt=f("clt",time=slice(0,1),longitude=(0,361),squeeze=1) # Read the time slice and squeeze it out
make directory for pngs if not present
import os
if not os.path.exists("pngs"):
os.makedirs("pngs")
import vcs
create new canvas
x = vcs.init(bg=True)
Create projection
polar = vcs.createprojection("rotate")
polar.type = "orthographic"
polar.centerlongitude=0.
polar.centerlatitude=45.
Create isofill method
iso = vcs.createisofill()
#iso.levels = range(0,110,10)
iso.levels = list(range(0,110,10))
#iso.fillareacolors = vcs.getcolors(range(0,110,10))
iso.fillareacolors = vcs.getcolors(list(range(0,110,10)))
iso.projection = polar
for centerLongitude in range(0,366,5):
polar.centerlongitude = centerLongitude
x.clear()
x.plot(clt,iso)
x.png("pngs/rotate_%s.png" % str(centerLongitude).zfill(6))
import glob
name = "rot_animation.mp4"
Create animation into file
#print "files used",glob.glob("pngs/rotate_*png")
print ("files used",glob.glob("pngs/rotate_*png"))
x.ffmpeg(name,sorted(glob.glob("pngs/rotate_*png")), rate=15)
