In geometry, a surface in 3-dimensional Euclidean space S is ruled (also called a scroll ) if through every point of S , there is a straight line that lies on S . Examples include the plane, the lateral surface of a cylinder or cone, a conical surface with elliptical directrix, the right c...
In differential geometry, Cayley's ruled cubic surface is the ruled cubic surface It contains a nodal line of self-intersection and two cuspital points at infinity. In projective coordinates it is x 3 + ( 4 x z + y w ) x = 0. {\displaystyle x^{3}+(4x\,z+y\,w)x=0.\ } . References External l...

A ruled surface is a surface that can be swept out by moving a line in space. It therefore has a parameterization of the form x(u,v)=b(u)+vdelta(u), (1) where b is called the ruled surface directri...
A ruled surface in differential geometry is a surface formed by a motion of a straight line. The lines that belongs to this surface are called (rectilinear) generators, and every curve that...
Allen's rule is an ecogeographical rule formulated by Joel Asaph Allen in 1877, broadly stating that animals adapted to cold climates have shorter and thicker limbs and bodily appendages than animals adapted to warm climates. More specifically, it states that the body surface-area-to-volum...
This paper considers a kind of design of a ruled surface. The design interconnects some concepts from the fields of computer-aided geometric design (CAGD) and kinematics. Dual unit spherical Bézier...
A ruled surface is a surface that is built up from an infinite number of perfectly straight lines.
