Upgrade animation 1

[Esteban82]

I think we should upgrade animation 1.

First of all, it has piping between gmt modules. This it is not advise and should be remove. Also, there is no need to use the commnad with gmt math and gmt convert.

It is possible to use gmt events instead of plot and movie -L instead of printf ... within the main script. I think we should change this.

Another change is to increase the number of frames created (and frame rate).

Here is an animation that I made:

New_anim01.mp4

Here is the script

# 1. Create files needed in the loop
cat << 'EOF' > pre.sh
gmt math -T0/360/10 T SIND = sin_point.txt
gmt math -T0/360/1 T SIND = sin_curve.txt
gmt begin
	gmt basemap -R0/360/-1.2/1.6 -JX22c/11.5c -X1c -Y1c \
	-BWSne+glightskyblue -Bxa90g90f30+u@. -Bya0.5f0.1g1 --FONT_ANNOT_PRIMARY=9p
gmt end
EOF
# 2. Set up the main frame script
cat << 'EOF' > main.sh
gmt begin
	gmt basemap -R0/360/-1.2/1.6 -JX22c/11.5c -X1c -Y1c -B+n

#	Plot smooth blue curve and dark red dots at all angle steps so far
	gmt events sin_curve.txt -i0,1,0 -T${MOVIE_FRAME} -Ar -Es -W1p,blue 
	gmt events sin_point.txt -i0,1,0 -T${MOVIE_FRAME} -Sc0.25c -Gdarkred
	
#	Plot bright red dot at current angle and annotate
	gmt events sin_curve.txt -T${MOVIE_FRAME} -Sc0.1i -Gred -i0,1,0 -L0

gmt end
EOF
# 3. Run the movie
gmt movie main.sh -Sbpre.sh -Chd -Tsin_curve.txt -Vi -D50 -NNew_anim01 \
	-Lf+t"a = %3.3d"+f14p,Helvetica-Bold+jTL+o1.25/1.15 -M35,png -Fmp4 -Zs
