VDB is an OpenVDB file - a sparse volumetric format for clouds, smoke and fire, storing only the voxels that actually contain data. OpenVDB, created at DreamWorks Animation, won an Academy Sci-Tech Award for making huge volumetric effects practical in film. Analyser handles .VDB alongside related formats such as .VOX, .DAE, .ZAE and more. In Analyser's format library, .VDB sits in the 3D / CAD / engineering category.

How do I open a .VDB file?

Drop a .VDB file onto Analyser at https://lab.valjdakosta.com/ and it is identified directly in your browser - no upload, no account and no software to install. Header and metadata extraction for 3D meshes, voxels, BIM, point clouds and Gaussian splats: MagicaVoxel VOX, COLLADA DAE/ZAE, USD crate, X3D/VRML, LightWave LWO/LWS, Quake MD2/MD3/MDL, VRM avatars, Siemens JT, LAS/LAZ/PCD/PTS/E57 LiDAR clouds, IFC BIM, and .splat/.spz - vertex/face/point counts, bounding boxes, units and authoring tool. glTF/GLB now open in a full 3D viewer - see the 3D model section.

Can I open a .VDB file online for free?

Yes. Analyser is a free online .VDB identifier that runs entirely in your browser - your .VDB file never leaves your device, so there is nothing to upload and no software to install. It even works offline once installed.

What Analyser reads: Header and metadata extraction for 3D meshes, voxels, BIM, point clouds and Gaussian splats: MagicaVoxel VOX, COLLADA DAE/ZAE, USD crate, X3D/VRML, LightWave LWO/LWS, Quake MD2/MD3/MDL, VRM avatars, Siemens JT, LAS/LAZ/PCD/PTS/E57 LiDAR clouds, IFC BIM, and .splat/.spz - vertex/face/point counts, bounding boxes, units and authoring tool. glTF/GLB now open in a full 3D viewer - see the 3D model section.
Depth of analysis: .VDB is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
Open a .VDB file: Drag a .VDB file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
