The unit PLOT3D displays data as three-dimensional colored surfaces which can be rotated on-screen. The rotation of the data can be achieved either by mouse interaction or by using built-in methods of the class. The data can be viewed from any direction, and can be zoomed and panned. Looking at the surface from above creates a color contour plot. More details can be found in the online help pages.

The unit PLOT3D is part of the SDL Component Suite.
