Algorithms for 3D-computer geometrical simulation for the problem of combination of a quadric and conic

The algorithms of 3d-computer geometric modeling on the example of the problem of combining a given parabola and a sheeted elliptic hyperboloid are given. Geometricallyexact solution of this problem is considered in a special case.For the general casethe solution based on a 3d-modeling of algorithms of a “black box” type is obtained.
