## Geometry

### Equations

• Assumption: Tiger is centered at the origin.
• Variables:
a ⇒ major radius of the tiger in the xy plane
b ⇒ major radius of the tiger in the zw plane
r ⇒ minor radius of the tiger
• All points (x, y, z, w) that lie on the surcell of a tiger will satisfy the following equation:

(sqrt(x2+y2) - a)2 + (sqrt(z2+w2) - b)2 = r2

x = acos(θ1) + rcos(θ1)cos(θ3)
y = asin(θ1) + rsin(θ1)cos(θ3)
z = bcos(θ2) + rcos(θ2)sin(θ3)
w = bsin(θ2) + rsin(θ2)sin(θ3)
total edge length = Unknown
total surface area = Unknown
surcell volume = Unknown
bulk = Unknown
