3.0.0

We are pleased to announce version 3.0 of the Polygon Mesh Processing Library! This is a major release with several additions and API changes. Highlights include:

• We integrated a polygon Laplacian that enables several algorithms to work on general polygon meshes, including smoothing, parameterization, fairing, and curvature computation.
• The geodesics in heat method has been added.
• The algorithms API has been revamped to use a simple function-based interface.
• New interactive online demos integrated into the algorithms guide.
• We no longer use git submodules for handling third-party dependencies.
• Upgrade C++ standard to C++17
• ... a whole lot of smaller fixes, cleanups, and improvements

See the changelog for a full summary of changes.

2.0.1

This is a minor bug fix release fixing the following issues:

• Fix shared library version
• Fix compilation with PMP_SCALAR_TYPE=64
• Use correct C++ standard (C++14) in public target compile options
• Fix crash in smoothing demo app

2.0.0

Version 2.0.0

Added

• Add support for texture seams in SurfaceSimplification, thanks to Timo Menzel.
• Add quad/tri subdivision, thanks to Hendrik Meyer.
• Add SurfaceFactory class to generate basic shapes. Thanks to u/lycium on Reddit for suggesting a simplification of the icosahedron() function.
• Add support to render colors per face
• Add support to render colors per vertex, thanks to Xiewei Zhong
• Add function to compute volume of a mesh, thanks to Xiewei Zhong
• Add post-increment iterators and make low level functions to add elements public. This makes it possible to use CGAL algorithms on a PMP SurfaceMesh. Thanks to Andreas Fabri for contributing the changes!
• Add PMP_INSTALL option to CMake.
• Add PMP_BUILD_VIS CMake option to enable / disable building the pmp_vis library and its dependencies.

Changed

• Bump C++ standard to C++14
• TriangleKdTree: no longer record number of tests, remove NearestNeighbor::tests member
• Remove SurfaceSubdivision::sqrt3()
• Remove PMP_SHOW macro
• Remove pmp::Version class and Version.h
• Build shared libraries on all platforms by default (except pmp_vis , see #87)
• Bump CMake minimum required version to 3.16.3
• Make SurfaceTriangulation::Objective a scoped enum
• Remove SurfaceMesh::triangulate() functions to avoid redundancy with SurfaceTriangulation
• Improve API by reporting errors using exceptions (see #16).
• SurfaceFeatures now returns the number of boundary / feature edges detected.
• Update Eigen to version 3.4.0
• Update GoogleTest to version 1.12.1
• Update stb_image to version 2.26 and stb_image_writer to version 1.15.
• Update GLFW to version 3.3.8
• Change CMake policy CMP0072 to "NEW" behavior preferring GLVND

Fixed

• Fix SurfaceMesh::get_object_propertyType() to get_object_property_type()
• SurfaceRemeshing: Don't leak feature properties. Spotted by Pierre Buyssens.
• Fixed a rare bug regarding ImGui scaling on Linux. Thanks to Jan Erik Swiadek for reporting and fixing this!
• Fix crash in SurfaceRemeshing when dealing with low quality meshes (#90, #89)
• SurfaceMesh::bounds() no longer includes deleted vertices. Thanks to Paul Du.
• Fix crash in SurfaceHoleFilling when a vertex selection already exists.
• Fix bug in SurfaceHoleFilling leading to artifacts in the filled surface patch. See #64.
• Change sign of vec2::perp() to correctly model CCW rotation by 90 degrees.
• Fix bug in OpenGL buffer clean-up in SurfaceMeshGL.
