Octoview for VS Code

Preview Gaussian splats, meshes, point clouds, arrays, tables, model metadata, scientific images, notebooks and HTML reports directly in VS Code.

Right-click a supported file in the Explorer and choose Octoview: Open Preview. You can also use Reopen Editor With... > Octoview Preview or run Octoview: Open Preview from the Command Palette for the active file. The preview is read-only and opt-in. Use Refresh to read changes saved to disk.

For automatic previews, open Settings > Extensions > Octoview > Auto Preview File Types and add file extensions such as .parquet. The list starts empty. Changes apply to subsequent file opens. Removing an entry removes only an editor association created by this setting. Existing Editor Associations for the same filename pattern and your manual changes to them are preserved. Other filename patterns follow VS Code's normal editor resolution rules.

For example, this setting opens Parquet and NumPy files directly in Octoview:

"octoview.autoPreviewFileTypes": [".parquet", ".npy"]

Supported extensions: .html, .htm, .ipynb, .glb, .gltf, .obj, .ply, .pcd, .npy, .npz, .parquet, .arrow, .feather, .ipc, .safetensors, .gguf, .onnx, .exr, .hdr, .tif, .tiff, .splat, .spz, .ksplat, .sog and .lcc.

LCC needs index.bin and data.bin beside the metadata file. glTF assets must be self-contained. Reports and notebook HTML outputs show static content in sandboxed frames. Notebook Plotly MIME outputs remain interactive.

Files stay on your machine or workspace host. There are no uploads, telemetry, GitHub credentials, or external resource downloads. The webview can access only packaged renderer assets. Reports cannot call VS Code APIs or run inline scripts. Git LFS pointers need git lfs pull before previewing.

Normal files and each LCC companion have a 64 MiB limit. Local .gguf and .safetensors files read only their first 32 MiB for metadata, so large weights stay on disk. Other filesystem providers have a 32 MiB model limit because the VS Code filesystem API cannot read byte ranges. Remote SSH workspaces run the extension on their workspace host. Unsaved editor changes are not previewed.

Build from the source repository:

npm ci
npm run build:vscode
code --install-extension build/octoview-vscode.vsix

Requires desktop VS Code 1.85 or newer and WebGL2 for 3D previews.
