The toraspherinder is a special case of a surcell of revolution where the base is a sphere.

Equations

  • Variables:
r ⇒ minor radius of the toraspherinder
R ⇒ major radius of the toraspherinder
  • All points (x, y, z, w) that lie on the surcell of a toraspherinder will satisfy the following equation:(?)
(sqrt(x2+y2+z2)-R)2 + w2 = r2
  • The parametric equations are:
x = r cos a cos b cos c + R cos b cos c
y = r cos a cos b sin c + R cos b sin c
z = r cos a sin b + R sin b
w = r sin a
total edge length = 0
total surface area = 0
surcell volume = 8π2Rr2
bulk = 8π2Rr33-1
