A quadric surface defined as second degree equation in x,y,z plane.By the depending upon the equation of surface their are many quadric surfaces are present.I give you one ex:We know that x^2/a^2+y^2/b^2=1 is represent the ellipse in 2-D but when we this equation on 3-D the it represents ellipsoid in xy-plane and whose Z axis value is zero i.e Z=0.

Quadric Surfaces

If a surface is the graph of an equation of second degree in three-dimensional Cartesian Coordinates, it is called a quadric surface. All plane sections of quadric surfaces are conics. Quadric surfaces are sometimes difficult to draw in two dimensions. This page is designed to help you explore the quadric surfaces from multiple angles. If you use your mouse to click on the graphs below you will be able to alter your view point of the surface. You can also start the graph rotating by moving the mouse slightly and then releasing.
