1.0.10

What's New

• Minimal build mode (-DWITH_3RD_PARTY_LIBS=OFF): Build CoACD without the bundled OpenVDB/Boost/TBB/spdlog dependencies. Input meshes must already be 2-manifold (manifold preprocessing is unavailable in this mode), and logging falls back to stdout. Useful for reducing binary size and build time when integrating CoACD into a larger project that doesn't need manifold repair.
• Windows 64-bit correctness fix: Fixed a pointer-truncation bug in the bundled Bullet convex hull code (btAlignedAllocator) where unsigned long was used to hold a pointer. On Windows (LLP64) unsigned long is 32 bits, so the cast truncated 64-bit addresses. Replaced with uintptr_t.
• Robustness: sobol now throws on error instead of calling exit(), so the Python bindings and library users can catch and handle sequence-generation failures instead of having the process killed.
• Build & CI:
  • CI now runs on pull requests, not just pushes to main.
  • Build step uses cmake -B and --parallel 4, bumped actions/checkout to v6.
  • Dropped -fPIC from global CXX flags in favor of the POSITION_INDEPENDENT_CODE target property.
  • Dropped -fpermissive and -D_USE_MATH_DEFINES on Linux/macOS (codebase doesn't need them; kept on MSVC because bundled OpenVDB headers reference M_PI).
  • Quickhull backport fixes and uninitialized-array warning fixes.
• Script fix: run_example.sh now uses -pm off instead of the non-existent -np flag for SnowFlake and Octocat examples.

Usage

# Minimal build (no OpenVDB / Boost / spdlog)
cmake .. -DCMAKE_BUILD_TYPE=Release -DWITH_3RD_PARTY_LIBS=OFF
cmake --build . --target main -j

1.0.9

What's New

• Real metric mode (-rm/--real-metric): Specify the concavity threshold directly in meters instead of normalized units. Ideal for meshes in real-world scale (e.g., from 3D scans or CAD models). The algorithm automatically converts it to the internal normalized threshold based on the mesh bounding box extent.

Usage

# CLI
./main -i model.obj -o output.obj -t 0.01 -rm

# Python
from coacd import Mesh, run_coacd
result = run_coacd(mesh, threshold=0.01, real_metric=True)
