A TRI file isn’t a standardized type but is widely used for triangulated mesh data that computers can process with ease, since 3D systems break objects into triangles because three points consistently define a flat surface, and once that’s done, the mesh is saved so the program doesn’t redo the demanding math, leaving the TRI file as an intermediate container with raw geometry like vertex coordinates and triangle indices that cut down on duplication while holding only what’s needed for the final shape.

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 regenerate 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 incomprehensible 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.

Sometimes, general-purpose file viewers or identification utilities can examine a TRI file well enough to reveal its type or basic layout, giving minimal clues about its role, but because they rely on nonstandard detection, their output varies, and since TRI files depend on the specific software that made them, the most dependable way to read them is through that program, viewing them as internal cache-like assets rather than files intended for user-level access.
