## space curve

[′spās ‚kərv]
(mathematics)
A curve in three-dimensional euclidean space; it may be a twisted curve or a plane curve.

## Space Curve

a curve in space. A space curve whose points do not lie in a single plane is said to be a twisted curve. Space curves have sometimes been called curves of double curvature.

If we wish to define a space curve in terms of Cartesian coordinates, we may view it as the intersection of two surfaces:

F(x, y, z) = 0 Ф(x, y, z) = 0

Alternatively, we may express it in parametric form:

x = ϕ(t) y = ψ (t) z = X(t)

Analogously, osculating curves in the Minkowski space-time are defined in [6] as the space curves whose position vector (with respect to some chosen origin) always lies in its osculating space, which represents the orthogonal complement of the first binormal or second binormal vector field of the curve.
The birational mappings of implicitly defined space curves find numerous applications in geometric modeling and computer graphics since they provide an efficient way of manipulating curves in space by processing curves in the plane.
