A 10 mm cube as 3MF: the modern OPC-packaged manufacturing format (a ZIP of model XML plus relationships). For testing 3MF readers and slicers.
A single-image 3D reconstruction of head and shoulders portrait of a south asian man in his fifties, written as binary glTF, geometry addressed through an accessor table. Its twin in this group is the same mesh written as the other format, from ONE reconstruction rather than two runs - so the pair tests whether a reader returns the same geometry from two containers with nothing in common. Both hold 28,536 vertices and 57,064 triangles; those counts were read from the GLB's accessor table and by counting lines in the OBJ, by separate code, and a disagreement would have stopped this shipping. It is closed: every edge belongs to exactly two triangles, so there are no holes and no non-manifold edges. The bounding box measures 0.3191 x 1.0247 x 0.8981 units.

A single-image 3D reconstruction of head and shoulders portrait of a young hijabi woman against a plain neutral studio background, written as binary glTF, geometry addressed through an accessor table. Its twin in this group is the same mesh written as the other format, from ONE reconstruction rather than two runs - so the pair tests whether a reader returns the same geometry from two containers with nothing in common. Both hold 29,272 vertices and 58,536 triangles; those counts were read from the GLB's accessor table and by counting lines in the OBJ, by separate code, and a disagreement would have stopped this shipping. It is closed: every edge belongs to exactly two triangles, so there are no holes and no non-manifold edges. The bounding box measures 0.2703 x 1.0417 x 0.9562 units.

A single-image 3D reconstruction of head and shoulders portrait of a smiling black man against a plain grey studio background, written as binary glTF, geometry addressed through an accessor table. Its twin in this group is the same mesh written as the other format, from ONE reconstruction rather than two runs - so the pair tests whether a reader returns the same geometry from two containers with nothing in common. Both hold 34,562 vertices and 69,120 triangles; those counts were read from the GLB's accessor table and by counting lines in the OBJ, by separate code, and a disagreement would have stopped this shipping. It is closed: every edge belongs to exactly two triangles, so there are no holes and no non-manifold edges. The bounding box measures 0.1821 x 1.032 x 1.0028 units.

A ground-floor plan for Alder Table Bistro as DXF R2010, 14.0 by 9.0 metres, 126.0 square metres gross with a 37.8 square metre kitchen. 8 AIA-style layers authored (10 in the file, because a DXF always carries layer 0 and Defpoints), two furniture blocks referenced rather than exploded, closed room boundaries so area is computable, aligned dimensions, a hatched kitchen floor and MTEXT notes. Seating is laid on a grid and stops when the floor runs out, so 26 covers are drawn. $INSUNITS is set to 6 (metres) rather than left at 0, because an unset unit is the single most common cause of a drawing importing at a thousand times its size. Synthetic premises, not a real building.
Binary buffer companion for the textured mini glTF (positions, UVs, indices).
The binary payload the external-buffer glTF in this group points at: tightly-packed positions, normals and indices with 4-byte alignment padding. Not viewable on its own: its bufferViews live in the JSON.
A ground-floor plan for Cedar Street Tacos as DXF R2010, 7.0 by 2.4 metres, 16.8 square metres gross with a 5.8 square metre kitchen. 8 AIA-style layers authored (10 in the file, because a DXF always carries layer 0 and Defpoints), two furniture blocks referenced rather than exploded, closed room boundaries so area is computable, aligned dimensions, a hatched kitchen floor and MTEXT notes.
