Below the same behavior is simulated for randomly generated points:
>point_list = []
>for n in range(10000):
>....point_list.append((random(), random(), random()))
> pic = point3d(point_list, color='red', size=1)
> pic.save(figsize=20)
I would like the points to be *very* small, since there are so many of them. It seems that "size" can only take positive integer values. As a workaround in point2d, you can make "figsize" much bigger, and the points stay the same size in pixels, which has the effect of scaling the point size down. But in point3d, when you make "figsize" bigger, you get the same picture, bigger. Could anyone help me make the points smaller?
Additionally, the default is for each point to be displayed as a little sphere, but I want it to be just a point. Again, in point2d, the code
> pic = point2d(point_list, color='black', size=1, marker='.' )
makes this happen, but when I do this in point3d they are still little spheres, and I cannot find any documentation about changing the marker for point3d.diana.davisTue, 11 Dec 2018 18:00:34 -0600http://ask.sagemath.org/question/44642/
