Object plots are used for modelling 3D geometries using combinations of object primitives such as line, triangle, quadrangle, cube, sphere, cylinder, disk, etc.

assorted objects

In this example we show a simple illustration of a piston inside a cylinder. It is fairly easy to modify the plot so that the piston follows an harmonic motion in the Z-direction.

Objects can also be combined with data. For example, we can combine the shore-line data with a sphere (close enough representation of the globe) and line objects to produce the following combination.

objects and data

A much better representation of the earth can be obtained using textures and a sphere object.
