The prism command takes a two-dimensional polygon plot structure and creates a three-dimensional regular prism of the height specified.

The option displacement=d can be used to create an oblique prism.

The plot data object produced by the prism command can be used in a PLOT3D data structure or displayed using the plots[display] command.

The plottools[prism] command was introduced in Maple 16.
