A TRI file isn’t defined by one specification but is commonly used to store triangulated mesh data so computers can process it faster, with 3D tools converting objects into triangles because three points reliably form a flat surface, and once calculated, the mesh is saved to avoid repeating the expensive computations, making the TRI file an intermediate format carrying basic geometry like vertex coordinates and triangle index sets that keep data lean by retaining only what’s necessary to represent the final shape.

Besides geometric data, many TRI files hold surface attributes that guide how an object should appear, including normal vectors for lighting direction, UV coordinates for texture placement, and sometimes optional details like vertex colors or material IDs, though these are not consistent between programs, and because TRI files are usually in a binary, software-specific format, files from different apps rarely align, making them unsuitable for manual modification and leaving them to act mainly as internal, cache-like assets that can be regenerated as necessary.

In everyday use, TRI files are usually fine to delete after the creating program has exited because the software can reproduce 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 junk 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.
