Restructure the web viewer so the wasm is a reusable module and add a second example that drives it from ordinary page DOM. Build: - Emit IfcViewerWeb.js (a `createIfcViewer` factory, MODULARIZE) + .wasm instead of a single baked page (dropped --shell-file); copy the static example pages next to it at build time. - Unbreak the web build: CameraMath.h / ViewportCore.cpp used boost::math::constants::pi just for pi, pulling all of boost/math into a header shared with the Emscripten build (no Boost in its sysroot). Replace with a constexpr kPiF — identical value, no dependency, desktop unaffected. JS integration (web/ifcviewer.js): - A small helper wraps the factory: boots the viewer on a canvas, runs the RAF loop from onRuntimeInitialized (NOT a post-await .then, which stalls Dawn-web's device callback and leaves the device half-initialised), and exposes addFile/addUrl, clearScene, model list/progress, and onSelect(...). - ViewportCore/main_web emit each pick to JS via Module.__ifcvOnSelect (object id + IFC GlobalId + model index; empty on deselect); onSelect also dispatches an 'ifcviewer:select' DOM event. - Fix input coords for a non-fullscreen canvas: mousemove/mouseup are window-targeted, so convert their coords to canvas-relative via the canvas client-rect origin (marquee + box-pick were offset when embedded). Examples: - IfcViewerWeb.html: the fullscreen viewer (same DOM/behaviour as before, now loading the module) — the Playwright smoke suite still targets it. - embedded.html: a sized viewer with DOM outside it to add models (file or URL), list loaded models with streaming progress, and show the model + GlobalId of the clicked object. Starts empty (drops the wasm's embedded sample, which the fullscreen page/tests still use). - index.html links both. Federation note: the web viewer already streams multiple models into one scene (a byte-source per file/URL); it doesn't need the desktop Federation document for this. Verified: 11/11 web smoke tests pass; embedded example loads models, reports the picked model + GUID, and the marquee aligns. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
IfcOpenShell
IfcOpenShell is an open source (LGPL) software library for working with Industry Foundation Classes (IFC). Complete parsing support is provided for IFC2x3 TC1, IFC4 Add2 TC1, IFC4x1, IFC4x2, and IFC4x3 Add2. Extensive geometric support is implemented for the IFC releases IFC2x3 TC1 and IFC4 Add2 TC1. Extending with support for arbitrary IFC schemas is possible at compile-time when using C++ and at run-time when using Python.
In addition to a C++ and Python API, IfcOpenShell comes with an ecosystem of tools, notably including IfcConvert (an application to convert IFC models to other formats), Bonsai (an add-on to Blender providing a graphical IFC authoring platform), and many other libraries, CLI apps, and more. Support is also provided for auxiliary standards such as BCF and IDS.
