Mesh

STL

.stl

STL is the most common triangle mesh format, widely used in 3D printing and CAD exchange. Both ASCII and Binary encodings are supported and auto-detected.

GLB

.glb

GLB is the binary format of glTF 2.0, packing meshes, textures and animations into a single file. Full PBR material, animation and topology selection support.

GLTF

.gltf

GLTF is the JSON-based format of glTF 2.0, referencing external .bin and texture files. Supports PBR materials, animations and topology selection.

3MF

.3mf

3MF (3D Manufacturing Format) is a 3D printing format promoted by Microsoft, supporting color and material information.

OBJ

.obj

OBJ is the classic Wavefront 3D text-based format, referencing external .mtl material library files.

PLY

.ply

PLY (Polygon File Format) stores vertex colors, normals and other attributes. ASCII and Binary are auto-detected.

FBX

.fbx

FBX is Autodesk's 3D exchange format, widely used in gaming and film industries, supporting meshes, materials and animations.

Collada

.dae

DAE (Collada) is an XML-based open 3D format supporting full scene graphs, materials and animation data.

3DS

.3ds

3DS is the classic format of Autodesk 3ds Max, widely used for legacy 3D content exchange.

USDZ

.usdz

USDZ is Apple's Universal Scene Description package format for AR and 3D content distribution.

Draco

.drc

DRC (Draco) is Google's compressed mesh format that significantly reduces 3D model file sizes, ideal for web transmission.

AMF

.amf

AMF (Additive Manufacturing Format) is an ISO standard 3D printing format supporting color, textures and multiple materials.

LWO

.lwo

LWO is LightWave 3D's model format, supporting polygon meshes and surface material attributes.

3DM

.3dm

3DM is Rhinoceros 3D (Rhino)'s native format, widely used in industrial design and architecture.

CAD

STEP

.step .stp

STEP is the most widely used 3D data exchange format in industrial CAD. Auto-imported and rendered with topology preservation, wireframe display and unit auto-detection.

IGES

.iges .igs

IGES (Initial Graphics Exchange Specification) is a classic CAD data exchange format widely used in engineering design and manufacturing. Converted to GLB via occt-import-js.wasm for rendering.

BREP (Boundary Representation) is OpenCASCADE's native boundary representation format, precisely describing face, edge and vertex topology of 3D geometry. Converted to GLB via occt-import-js.wasm for rendering.

FreeCAD

.fcstd

FCStd is FreeCAD's native format — a ZIP package containing XML documents and embedded BREP geometry. The app extracts and converts it to GLB via the OCCT engine.

OpenSCAD

.scad

SCAD is OpenSCAD's script-based format that describes 3D geometry programmatically (cubes, spheres, cylinders combined via boolean operations). Compiled and converted to GLB via openscad-wasm for rendering.

DXF

.dxf

DXF (Drawing Exchange Format) is Autodesk's CAD data exchange format, widely used for 2D engineering drawings and 3D model exchange.

BIM

IFC

.ifc

IFC (Industry Foundation Classes) is the international standard data format in the BIM domain for digital description of buildings and infrastructure. Parsed and rendered via the web-ifc library.

Animation

BVH

.bvh

BVH (Biovision Hierarchy) is a motion capture data format, rendered as skeleton hierarchy animations.

MD2

.md2

MD2 is the model format used by Quake II engine, supporting vertex animation — a classic game model format.

Point Cloud

XYZ

.xyz

XYZ is a simple point coordinate format with X/Y/Z values per line, rendered as a point cloud.

PDB

.pdb

PDB (Protein Data Bank) is the protein structure format. Atoms and bonds are rendered as point clouds and lines.

PCD

.pcd

PCD (Point Cloud Data) is Point Cloud Library's standard format storing 3D point coordinates and attributes.

Volume

VTK

.vtk .vtp

VTK (Visualization Toolkit) is the standard data format in scientific visualization, supporting multiple data types.

NRRD

.nrrd

NRRD (Nearly Raw Raster Data) is a volume data format in medical and scientific imaging, supporting multi-dimensional raster data.

GCode

.gcode

GCode is the instruction set for 3D printer toolpaths. This app renders the movement trajectories as 3D line segments.

Vector

SVG

.svg

SVG (Scalable Vector Graphics) is an XML-based 2D vector graphics format widely used for web icons, illustrations and UI design.
