Module containing Perl functions that can be referenced and used by Perl programs; may be one of two different types:

1) Traditional - defines subroutines and variables for the function referencing the module to import and use.

2) Object-oriented - functions as a class definition and is accessed through method calls.

Some Perl modules may offer traditional and object-oriented functionality.

A PM file is a 3D model used by legacy versions of Trainz Railroad Simulator. It contains data used to show a train car or other object in-game. The PM format was replaced by the .IM format.

Trainz Railroad Simulator is a video game in which players simulate routing and operating trains. The first version of the game, titled simply Trainz, was released by Auran in 2001. The game has since received many sequels. It is now published by N3V Games.

Previous versions of Trainz used 3D models saved in the PM format, or Progressive Mesh, format. This format supported a specialized, multi-faceted form of level of detail specification.

However, advances in graphics technology rendered the PM format obsolete. Instead, Trainz began using IM, or Indexed Mesh, models, which contained a single level of detail specification.

You can use PEVSoft Trainz Mesh Viewer 2 (Windows) to view the 3D model a PM file contains. There is no program that allows users to edit PM files.

You can use PEVSoft PM2IM (Windows) to convert a PM file to the .IM (Indexed Mesh) format. This allows you to use the model your PM file contains with later versions of Trainz Railroad Simulator.
