.PM

Unix XV Graphic File

📌 The primary, major assignment of the .PM specification category concerns the bitmap image pattern built up and opened by the Unix toolkit “xv”, an interactive image manipulation solution for the X Window System infrastructure. Moreover, the current .PM extension algorithm is also taken into service by IBM’s OS/2 Presentation Manager.

Perl Module

📌 One more obvious case of the .PM layout exploitation refers to a compound module consisting of Perl functions that can be employed and referenced by certain Perl packages. Actually, the .PM data instances can be represented by one of two different categories:

1. Object-oriented - Featured as a class definition and is accessed through method calls.
2. Traditional - Defines variables and subroutines for the corresponding function referencing the .PM module to use, open, and import.

Some distinguished Perl modules may provide object-oriented and traditional functional range.

Progressive Mesh

📌 A .PM structure corresponds to the 3D model applied by legacy editions of Trainz Railroad Simulator, an archaic game in the railroad construction and planning genre. Specifically, the .PM extension basement includes data applied to visualize a train car or other in-game object. Later the .PM format approach was superseded by the .IM technical entitlement.

Trainz Railroad Simulator can be described as a formerly popular video-game in which players simulate operating trains and routine tasks. The very first edition of the series, named simply as Trainz, was released in 2001 by Auran company. Since then the franchise has obtained many sequels. It is now published by N3V Games studio.

Previous builds of Trainz simulator applied 3D models stored in the .PM shape, or Progressive Mesh make-up. This technological .PM bundled principle supported a specialized, multi-faceted shape of level of detail specification.

Nevertheless, advancement in graphics technology rendered the .PM file layout obsolete. On the opposite way, Trainz started using IM, or Indexed Mesh, models, which included a single level of .PM wrapped detail representation.

How to open an .PM file?

📌 The .PM file pattern takes the service of XnViewMP, Lemkesoft GraphicConverter, Newera Graphics Converter Pro, or command-prompt xv utility, able to retrieve, investigate, open, and analyze the .PM item build-up. Moreover, in certain preconditions the .PM file elements can be operated and surveyed by MacroMates TextMate, Bare Bones BBEdit, or any common text editor, available on your PC workstation or client device. Pretty rarely, the .PM data formation can be also operated by Trainz Simulator, PM2IM, or Trainz Mesh Viewer utilities, eligible for simulating operating and routing trains. Although the Trainz Simulator is pretty outdated and obsolete, you can easily download the earlier published distributive edition from the archive repositories and servers.
