HOOPS Visualize Web 2026.8.0

Technology Update

Breaking change: Node.js and npm are no longer included in the package (the 3rd_party/node directory has been removed), and the HOOPS Server dependencies (server/node/node_modules) are no longer shipped. Node.js and npm must be installed separately and available on your PATH. The start_server scripts now run npm install to download the server dependencies before starting the server. See Advanced Setup for details.
The Linux customer package now includes a Dockerfile in authoring/converter/. From the package root, build a self-contained converter image with docker build -t hoops-converter authoring/converter. The image is officially available from Docker Hub as techsoft3d/hoops-converter.
SBOM files in CycloneDX (*.cdx.json) and SPDX (*.spdx.json) formats are now available in the package’s sbom/ directory.

Added support for importing E57 point cloud files on Windows.
The demo app’s right-click context menu color picker now opens correctly in Safari.
Added two new HOOPS Converter import options, --read_construction_and_references and --treat_long_wireframe_as_construction_and_references, to control how HOOPS Exchange imports construction/reference geometry and long wireframe entities. These options are also available as XML batch input attributes.
Added autoFlipPMI setting on WebViewer: when enabled, PMI main bodies automatically rotate 180° around their local up axis to keep their front face toward the camera. This requires models to be converted with this release or later, or to have their orientation authored directly through the libsc authoring API; PMI in models converted with earlier converter versions will not flip until they are re-converted. See here under Auto Flip PMI for details.
The <hoops-settings-panel> component and PmiService now support the autoFlipPMI setting.
Updated 3dconnexionjs to version 0.8.1.
Added new component hoops-filter-list to the @ts3d-hoops/web-viewer-components package.

Breaking change: <hoops-node-properties> moved from @ts3d-hoops/ui-kit to @ts3d-hoops/web-viewer-components and is no longer exported by @ts3d-hoops/ui-kit. Its class was also renamed from NodeProperties to HoopsNodePropertiesElement to align with the naming convention of other components in @ts3d-hoops/web-viewer-components.
Breaking change - removal of the ``Sc`` export: The Sc export has been removed from the web-viewer API. All types previously available under Sc are now exported directly from the top level of the API.
Added read_construction_and_references and treat_long_wireframe_as_construction_and_references to SC_Import_Options in libconverter. They match the new Converter options of the same name.
