Indexed Mesh Format
An IM file is a 3D model file format previously utilized by older versions of Trainz Railroad Simulator. It houses data vital for rendering in-game objects like train cars. The IM format was a successor to the .PM format and, in turn, was eventually superseded by the .FBX format.
PPM, which stands for Portable Pixmap, is a straightforward image storage format. It supports three types of images: color (PPM), grayscale (PGM), and black and white (PBM). These formats are particularly useful as an intermediary representation during the conversion of raster image files between different platforms. The development of the PPM format is credited to Jeff Poskanzer.
