What Anyfile can show

Plain OFF vertex positions and indexed polygon faces
Triangulated surface geometry with rotation and standard views

Limits and conditions

Colored or normal-bearing variants such as COFF and NOFF, and extra attribute records, are not supported
Simple fan triangulation can misrepresent concave polygons; triangulate them in the source tool for a reliable preview
128 MiB input with vertex/face limits; no texture loading or topology repair; WebGL 2 required

IMPLEMENTATION

Viewers responsible for this format

Object File Format begins with OFF, followed by element counts, vertex coordinates and face indices. It is a compact way to exchange polygon connectivity without a material package. Anyfile triangulates supported faces for display and calculates normals for the shaded surface.

Common question

Why is my COFF file rejected by the OFF viewer?

COFF includes color attributes and a different header. This parser expects plain OFF structure and rejects extra attributes rather than treating them as coordinates or face indices.

Why can a concave OFF face look incorrect?

The preview splits each polygon into a fan of triangles. This simple construction is suited to convex faces; complex concave faces should be triangulated before export.
