Having seen the whole program, I realized that there's a missing "num +=
1" in the while loop in add_points, which meant that you were creating
an infinite number of spheres. After that correction, however, on my
machine rotating the view was sluggish until I changed from sphere to
points, in which case the program runs very fast and rotation is smooth:
def simulate_hyper():
from visual import rate, points #sphere
positions = points()
def add_points():
num = 0
while num < 1000:
positions.append(pos=get_point())
## sphere(pos=get_point(), radius = 2**55)
num += 1
