solidcore is a Rust port of SMLib, the NURBS B-rep solid modeling kernel by NVIDIA, published as part of USD BRep:

Upstream material used
Only these upstream paths are read, ported or exercised:
| Upstream path | Use |
|---|---|
source/SMLib/ |
Kernel being ported (geometry, topology, algorithms) |
source/SM_API/ |
High-level API being ported; reference for public ops |
tests/SM_API_test/ |
Reference tests; source of difftest cases |
tests/prog_test/ |
Reference tests; source of difftest cases |
TestFiles/pt_TestFiles/ |
Test fixtures |
AGENTS.md, .agents/ |
Upstream developer documentation (OCCT/USD files excluded) |
LICENSE, THIRD_PARTY_NOTICES.md |
Licence text and notices |
The C++ reference build (harness/cpp) compiles only source/SMLib and
source/SM_API, from a local clone that is never committed (upstream/ is
gitignored).
Upstream material not used
The following upstream layers are not read, ported, built or linked:
- OCCT translation:
source/OCCT_BREP_IMPORT,source/OCCT_BREP_EXPORT,TestFiles/occt_breps* - USD / Hydra integration:
source/SM_API_USD,source/BREP_SM_USD,source/BREP_USD_DATA,source/HYDRA_USD_BREP,source/USD_BREP_UTILS,source/schema,TestFiles/usd_TestFiles - Python bindings and tooling:
source/SmPyLib,source/SmPyDevLib,tools/ - Proposals:

No GPL/LGPL code is used anywhere in solidcore.
Per-file provenance
Every ported Rust file begins with a header naming the upstream source file(s) it
derives from and a table mapping its Rust items to upstream names (see
AGENTS.md).
