I am using sage for my calc III students. The following short code
produces about 500 points on a sphere.
pts=[]; number_of_points=500
for t1 in srange(0, pi, n(pi/sqrt(number_of_points))):
for t2 in srange(0, 2*pi, n(2*pi/sqrt(number_of_points))):
pts.append((sin(t1)*cos(t2), sin(t1)*sin(t2), cos(t1)))
show(point(pts))
My question is, though, that sage takes, it seems to me, longer time
to execute this than I would expect. (CPU time: 6.66 s, Wall time:
48.84 s) Am I making some stupid mistake in the above code, or sage
does something unnecessary, which causes the delay? In my (naive)
point of view, plotting as many as 500 points shouldn't take that long
time... Thanks.
