Conoid - Wikipedia 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
Conoid -- from Wolfram MathWorld A conoid is a ruled surface whose rulings are parallel to a plane (called the directrix plane) and intersect a fixed line (called the axis of the conoid) (Gellert et al 1989, p 202)
CONOID - MATHCURVE. COM A conoid is a ruled surface the generatrices of which stay parallel to a plan (P), called directrix plane of the conoid, while intersecting a line (D), called axis of the conoid; it is therefore a Catalan surface When (P) and (D) are perpendicular, the conoid is said to be right
Cone vs Conoid - Whats the difference? - WikiDiff In geometry terms the difference between cone and conoid is that cone is a solid of revolution formed by rotating a triangle around one of its altitudes while conoid is a solid formed by the revolution of a conic section about its axis
Conoid - scientificlib. com 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
Right Conoid - Virtual Math Museum Right Conoid is a ruled surface It is generated by moving a line segment S perpendicular to a fixed line L, in the direction of the L, while S rotates around L When S has rotated 180 degrees, the direction of travel is reversed The construction of Right Conoid is similar to a Helicoid
