- The
helicoid, also
known as
helical surface, is a
smooth surface embedded in three-dimensional space. It is the
surface traced by an
infinite line that...
-
helix – for example, a "spiral" (helical) ramp – is a
surface called a
helicoid. The
pitch of a
helix is the
height of one
complete helix turn, measured...
- In geometry, a
generalized helicoid is a
surface in
Euclidean space generated by
rotating and
simultaneously displacing a curve, the
profile curve, along...
- ****ociate
family of surfaces, a
catenoid can be bent into a
portion of a
helicoid, and vice versa. The
catenoid was the

- In
fluid dynamics, an
isotropic helicoid is a
shape that is helical, so it
