A TRI file is not formally standardized but is usually used for triangulated mesh data that is easy for computers to process, since 3D software converts shapes into triangles because three points ensure a stable flat plane, and saving this output prevents repeating the costly math, leaving the TRI file as an intermediate record with raw geometry like XYZ vertices and triangle indices that trim down the data while holding only what the final mesh needs.

In addition to geometric points and triangles, TRI files frequently carry surface information that ensures accurate display, like normal vectors for lighting and UV coordinates for texture mapping, with optional extras such as vertex colors or material identifiers that vary by application, and because TRI files are stored in binary using program-specific layouts, two files from different software may be incompatible, so TRI files aren’t intended for hand editing and mainly serve as internal, cache-style assets that the software can recreate whenever needed.

In everyday use, TRI files are usually fine to delete after the creating program has exited because the software can recalculate them on demand, though doing so may slow down the next session, since these files serve as temporary, optimized snapshots rather than files meant for users, and because their internal structure is unique to each program, they can’t be opened like common file types, resulting in the absence of a universal viewer and huge differences in how various applications fill their TRI files.

On rare occasions, a TRI file stored as text can be opened with basic editors to show coordinates or triangle lists, but most TRI files are binary and tuned for fast processing, so text editors will display garbled symbols due to their encoding, and since these files serve as intermediate geometry caches meant for the software’s internal use, they are normally accessed only by the program, leaving manual opening outside that environment nearly useless.

There are times when multi-format viewers or identification tools can inspect a TRI file just enough to expose simple metadata or structural hints, which can help determine its purpose, but these tools rely on heuristics and may produce uneven results, and since TRI readability depends on the software that created it, the most reliable approach is to open it indirectly through that program, viewing TRI files as internal cache-like components rather than items for manual editing.
