Changelog

All notable changes to this project are documented in this file.

The format is based on Keep a Changelog.

This project aims to adhere to Semantic Versioning.

Unreleased

Added

  • Add support to read non-manifold meshes by duplicating vertices
  • 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 @afabri 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

  • MeshViewer::load_mesh() again returns boolean success value.
  • 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-rc1
  • Update googletest to version 1.10.0
  • Update stb_image to version 2.26 and stb_image_writer to version 1.15.
  • Update GLFW to branch 3.3-stable to fix keyboard input on Linux.
  • Change CMake policy CMP0072 to "NEW" behavior preferring GLVND

Fixed

  • Fix bug in hole filling 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.

[1.2.1] 2020-05-10

Fixed

  • Fix rendering issues around sharp edges
  • Fix bug in adaptive remeshing leading to over-refinement of corner vertices.
  • Fix bug in bounding box computation. Thanks a lot to Jascha Achenbach for reporting this bug!

[1.2.0] 2020-03-15

External libraries

  • Upgrade Eigen to current master version to get rid of a compile error on Windows
  • Upgrade ImGui to version 1.75
  • Upgrade stb_image to current master version

Added

  • Add constructors using initializer lists to Matrix/Vector classes
  • Add assignment from and cast from Eigen matrices and vectors
  • Improved rendering of general polygons, avoiding erroneous tessellation into overlapping/flipped triangles in case of non-convex polygons.
  • Added support for rendering using MatCaps. Thanks to Alec Jacobson for suggesting this!

Fixed

  • Fix erroneous header install path (visualization)
  • Fix bug hole filling (when filling single-triangle holes). Thanks a lot to Pierre Buyssens for reporting this bug!
  • Fix bug when fairing a mesh w/o boundary constraints. Thanks a lot to Pierre Buyssens for reporting this bug!

[1.1.0] 2019-05-30

Added

  • Compile-time switch PMP_SCALAR_TYPE to choose between float/double as Scalar
  • Support point set rendering for surface meshes without faces
  • Add hole filling based on Liepa algorithm
  • Add explicit warranty and liability disclaimer

Changed

  • Breaking change: Public members in Window and TrackballViewer classes made private and encapsulated through access functions
  • Change SurfaceSmoothing to avoid model shrinking
  • Improve normal computation for polygonal faces
  • Upgrade GLFW to version 3.3
  • Upgrade ImGui to version 1.70
  • Upgrade Eigen to version 3.3.7
  • Documentation updates

Fixed

  • Fix a bug in OFF reader when loading faces with high valence
  • Fix a bug SurfaceGeodesic that lead to dist(v0,v1) != dist(v1,v0). As a consequence, the Novotni method has been removed from SurfaceGeodesic.

  • Unit test suite
  • Continuous integration
  • Coding standard
  • Version API

Changed
