A TRI file isn’t built on one global format but is mostly used to store triangulated mesh data that computers can handle efficiently, because 3D systems convert shapes to triangles as three points define a reliable flat surface, and the converted mesh is saved to avoid repeating the same heavy calculations, making the TRI file a derived format containing raw geometry such as vertex coordinates plus triangle index sets that avoid duplicate data by storing only the essentials of the finished shape.

Beyond basic geometry, TRI files often contain surface data needed for proper display, including normal vectors for lighting, UV coordinates for texture mapping, and occasionally extras like vertex colors or material tags, though what appears depends on the software, and because the format is usually stored in a binary, program-dependent structure, files from different tools may not match, meaning TRI files are generally not intended for manual editing and instead act as internal cache-style assets that can be rebuilt whenever required.

In normal workflows, TRI files may be deleted harmlessly after closing the software because the application can reconstruct them whenever required, causing only slower loading next time, as they function like temporary optimized geometry caches rather than files intended for users, and since their binary structure is proprietary to each program, they cannot open like ordinary formats, leaving no universal viewer and allowing different applications to populate the .TRI extension with entirely different kinds of data.

If a TRI file is saved in a text format, it might open in basic editors like Notepad and reveal coordinates or triangle setups, though this is unusual because most TRI files are binary and optimized for loading performance, so a text editor will display random-looking characters that aren’t errors but merely binary content, and because TRI files serve as behind-the-scenes intermediates for faster geometry handling, they are meant to be accessed only by the program that made them, leaving manual inspection mostly pointless.

On occasion, broad file-viewing tools or file-identification programs can partially open a TRI file to show hints of structure or metadata, though their findings are based on heuristics rather than a true format specification, making results limited, and because TRI files are tightly bound to their originating application, the correct way to access their contents is through that software, while treating TRI files as background assets not designed for direct human use.
