A TRI file is not formally standardized but is usually used for triangulated mesh data that is optimized for fast computation, since 3D software converts shapes into triangles because three points give 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 minimize file bulk while holding only what the final mesh needs.

In addition to basic geometry, many TRI files include surface details that help software display a model correctly, such as normal vectors that describe surface direction for lighting and shading, UV coordinates that map textures, and sometimes optional data like vertex colors or material IDs, though these extras vary, and because most TRI files use compact binary structures that are undocumented, different applications may produce incompatible versions, making these files unsuitable for manual editing and leaving them to function mostly as internal cache-like assets that the software can regenerate when needed.

Typically, TRI files can be deleted safely after the program shuts down because the software can recreate the needed data later, causing only minor slowdowns on the next load, as these files act as temporary performance boosts rather than user-oriented formats, and since their structure is proprietary and tied to the program that made them, they cannot open like standard files, which is why no general TRI viewer exists and why different applications often embed completely different info within similarly named TRI files.

While a text-based TRI file may open in editors like Notepad and show geometry details, this is uncommon because most TRI files are binary for performance reasons, and opening them in a text editor results in scrambled text that simply represents binary structure, and given that TRI files exist chiefly as intermediate assets for faster computations, they are intended to be read only by the originating program, making manual access outside that context largely unhelpful.

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 heuristic checks, 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.
