An interactive three dimensional plot with axes labeled
\(x\) and
\(y\) horizontally and
\(z\) vertically. A titled plane is shown in gray with a central point labeled
\((0,0,3)\text{.}\) Seven paths are shown in red moving along the surface toward the central point. The same shape paths are drawn in blue on the
\(xy\)-plane moving toward the origin.
