Abstracts
The S^2×R geometry is derived by direct product of the
spherical plane S^2 and the real line R. In [9] the third author has determined the geodesic curves, geodesic balls of S^2×R space, computed their volume and defined the notion of the geodesic ball packing and its density. Moreover, he has developed a procedure to determine the density of the geodesic ball packing for generalized Coxeter space groups of S^2×R and applied this algorithm to them.
E. MOLNÁR showed in [3], that the homogeneous 3-spaces have a unified interpretation in the projective 3-sphere
PS^3(V^4,V_ 4,R). In our work we shall use this projective
model of S^2×R geometry and in this manner the geodesic
lines, geodesic spheres can be visualized on the Euclidean
screen of computer.
Furthermore, we shall define the notion of the equidistant surface to two points, determine its equation and visualize it in some cases. We shall also show a possible way of making the computation simpler and obtain the equation of an equidistant surface with more possible geometric meaning. The pictures were made by the Wolfram Mathematica software.

Keywords
non-Euclidean geometries; projective geometry; geodesic sphere; equidistant surface
