IFClite

IFClite merged PR #1182, a contribution from Mathias Sønderskov Schaltz that lets IFClite parse IFC inside the CAD process — as a plain DLL. The clean way to call a Rust engine from Grasshopper or Revit used to mean running a local server and talking to it over HTTP. But the moment something opens a port on a managed machine, enterprise IT lights up: firewall rules, security reviews, the whole dance. The FFI wires IFClite straight into the process instead. A new ifc-lite-ffi crate builds with crate-type = ["cdylib"] to ifc_lite_ffi.dll, and the host loads it like any other library. No server. No port. No network. Just a function call. ...

IFClite has merged PR #1024, replacing its two boolean backends with a single pure-Rust exact CSG kernel. The browser build previously relied on the C++ Manifold library via WASM cross-compilation; the native server path used an in-tree BSP port. Both are gone. The new kernel is a clean-room mesh-arrangement implementation: operand meshes are intersected conformingly (shared symbolic vertices for line-plane and triple-plane intersection points), re-triangulated under exact predicates, then classified for difference, union, or intersection. Every topology decision routes through a predicate cascade (interval filter, fixed-width tier, BigRational oracle) built on Shewchuk adaptive predicates for explicit coordinates and Cherchi-style indirect predicates (Attene 2020) for implicit intersection geometry. The public API (processGeometryBatch, SDK surface) is unchanged; consumers see different triangulations wherever booleans fire. ...

Louis Trümpler announced that point clouds are coming to IFClite as part of the same browser-native openBIM workflow, rather than as a separate viewer or visual overlay. The first pass includes LAS / LAZ streaming, E57 / PLY / PCD readers, Web Worker decoding, WebGPU point rendering, colour modes for RGB, classification, intensity, height, and fixed colour, plus federation-aware point picking. ...

Louis Trümpler announced federated loading support in IFClite, a browser-native IFC viewer and toolkit built with WebGPU and Rust/WASM. For IFC4.3 and earlier workflows, federation means loading multiple IFC models side by side with collision-safe IDs, per-model visibility, unified spatial hierarchy handling, and selection across model boundaries. ...
