Conoid shell
http://mybloggertricks.org/conoid_shell.html In geometry a conoid (from Greek κωνος 'cone', and -ειδης 'similar') is a ruled surface, whose rulings (lines) fulfill the additional conditions: (1) All rulings are parallel to a plane, the directrix plane. (2) All rulings intersect a fixed line, the axis.The conoid is a right conoid if its axis is perpendicular to its directrix plane. Hence … See more Right circular conoid The parametric representation $${\displaystyle \mathbf {x} (u,v)=(\cos u,\sin u,0)+v(0,-\sin u,z_{0})\ ,\ 0\leq u<2\pi ,v\in \mathbb {R} }$$ describes a right circular conoid with … See more • mathworld: Plücker conoid • "Conoid", Encyclopedia of Mathematics, EMS Press, 2001 [1994] See more Mathematics There are a lot of conoids with singular points, which are investigated in algebraic geometry See more
