Release v3.0.4.121

MeshLib SDK v3.0.4.121 Released

Smarter, Faster, More Scalable Mesh Processing

The latest MeshLib release brings a powerful range of enhancements, from performance upgrades and CUDA acceleration to improved usability and expanded developer tooling. Version v3.0.4.121 strengthens our mission to provide an advanced, developer-friendly toolkit for real-time 3D data processing.

1. Robust Developer Enhancements

C Bindings & Python Testing

• Added C binding tests and improved Python DICOM samples
• Moved embedded Python to a separate library, improving modularity and build efficiency
• Fixed critical deadlocks in embedded Python shutdown

CMake & Build Improvements

• Improved compatibility with Windows and Visual Studio 2019
• Introduced vcpkg support on Linux for streamlined dependency management
• Enhanced build pipeline with resource packaging and better artifact handling

CI/CD & Debugging Tools

• Wasm distribution now supported and testable in headless browser mode
• Unified logging macros for easier C test output
• Extended error handling and better diagnostics across the build system

2. New Mesh Operations & Geometry Tools

Subdivision & Mesh Processing

• Added subdivideMesh() with support for custom regions and face selections
• Introduced fillPlanarHole() and improved cutMeshByPolyline() for advanced editing workflows
• Implemented PolylineTopology::makeEdge() equality checks and optimized section extraction with AABB trees

Radius Compensation & Offset Tools

• Multiple refinements and speed-ups to vertex-based radius compensation
• Greater control and precision tuning for offsetting operations
• Enhanced meshToVolume and voxel fusion workflows with better filtering by object type

Topology & Rendering Fixes

• Improved MeshTopology::checkValidity() and handled empty object rendering crashes
• Added cubic Bézier curve support and linear interpolation tools (lerp), enabling smoother geometry transitions

3. CUDA & Parallel Acceleration

• Chunked processing added to CUDA-based winding number algorithms
• Ported point-to-point-cloud distance to CUDA
• Added triangulation for CUDA-based fusion (pointsToMeshFusion)
• Experimental HIP support introduced for broader GPU compatibility
• Ensured thread safety and optimized AABB tree traversal

4. UI/UX & Usability Upgrades

• Unified ribbon layout customization and enhanced move tool controls (including dead zone and non-uniform scaling)
• Added side rotation arrows in the corner controller for intuitive object rotation
• Improved point picking, tooltip visibility, and object tree logic

5. Better Documentation & Examples

• New manual build guide for advanced users
• Improved error messages for unsupported mesh and DICOM files
• Cleaned up test structure and extended coverage for mesh, voxel, and UI modules

6. Bug Fixes & Stability Improvements

• Fixed compatibility issues with Clang 18, GTest-free builds, and setlocale() crashes
• Improved file handling with better error reporting when loading meshes and DICOMs
• Refined internal tools and removed unused or conflicting project properties

MeshLib SDK v3.0.4.121 continues our focus on performance, flexibility, and developer control—especially for teams building advanced 3D workflows, mesh processing apps, and GPU-accelerated pipelines.
