For the organelle called conoid used by intracellular parasites, see myzocytosis.

The hyperbolic paraboloid z=xy is a conoid with x-axis as its axis.

The hyperbolic paraboloid z=xy is a conoid with y-axis as its axis.

In geometry, a conoid is a Catalan surface all of whose rulings intersect a fixed line, called the axis of the conoid. If all its rulings are perpendicular to its axis, then the conoid is called a right conoid.[1]

For example, the hyperbolic paraboloid z = xy is a conoid (in fact, a right conoid) with x-axis and y-axis as its two axes.

A conoid can be represented by parametric equations

where {ℓ, m, n} is a vector parallel to the axis of the conoid and ƒ(u) is some function.

If ℓ = m = 0 and n = 1, then the conoid is a right conoid.
