GLB · glTF(+.bin) · OBJ · STL · PLY · FBX — parsed locally
100%
Open any Wavefront .obj file and inspect it under studio light — geometry is parsed right in this tab.
01 — Local
Parsing and rendering happen entirely in this tab. Your file is never uploaded to a server.
02 — PBR
Studio lighting with real environment reflections, orbit, zoom and frame-to-fit. Animation clips play back when present.
03 — Stats
Mesh count and triangle totals are reported on load, with geometry rendered under studio lighting whether or not a .mtl ships with it.
Questions people ask
- What exactly is inside an OBJ file?
- Plain-text vertex positions, normals and UV coordinates. Materials live in a companion .mtl file; this viewer reads the geometry from the .obj itself and shows it under studio lighting. OBJ carries no animation by design.
- Can I convert OBJ to GLB?
- Yes, locally and free: geometry, normals and UVs carry across into GLB. Plain OBJ has no PBR material definitions, so expect default material slots in the result.
- Why do old meshes keep arriving as OBJ?
- OBJ is the oldest widely-shared mesh format and nearly every 3D tool ever made can write it. It remains the safest interchange format when you do not know what the receiving tool supports.
