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

• The hypervolumes of a toraspherinder are given by:

total edge length = 0
total surface area = 0
surcell volume = 8π²Rr²
bulk = 8π²Rr³3^-1

• The realmic cross-sections (n) of a toraspherinder are:
