I try to save a movie of a trajectory using the following routine..
Since IDL plots every frame on my screen the whole thing is EXTREMELY
slow.. How can i do this without viewing each frame on my screen? I
think this is done with Z buffer but i dont know how to include this
in my routine:
; number of frames
nfr=100
; spatial size
xsize=200
ysize=200
; open mpeg
mpegID=MPEG_OPEN([xsize,ysize])
; loop over frames
img_dummy=fltarr(10,10)
SURFACE, img_dummy,$
xstyle=1,ystyle=1,xrange=[-60.0e-7,60.0e-7],yrange=[-60.0e-7 ,0.0],$
ZAXIS=3,zrange=[0.0,10.0e-5],zst=1,ax=20,az=10,/SAVE,/NODATA
for j=1,nfr do begin
plots, x((j-1)*10:j*10), y((j-1)*10:j*10), z((j-1)*10:j*10),$
/T3D,/DATA,Thick=2
; add the plot to mpeg
MPEG_PUT,mpegID,WINDOW=0,FRAME=j-1,order=1
endfor
; save movie and close the file
MPEG_SAVE,mpegID,FILENAME='movie.mpg'
MPEG_CLOSE,mpegID
