All notable changes to this project will be documented in this file. See standard-version for commit guidelines.

3.8.0 (2022-01-06)​

Features​

Bug Fixes​

  • TreeItem now correctly exports the visibility state value. (d69e4ad)

3.7.0 (2021-12-06)​

Features​

  • Exported new types for use in Custom Properties (Vec2_32si, Vec2_32ui, Xfo_32f) (d5812fb)

Bug Fixes​

  • Cleaned up unreliable detection of non-uniform scale. (396c355)
  • Geom hashing now avoids matching geoms of different types. This addresses and issues where a lines and a mesh have the same number of points and every other property is the same. (c709a9b)
  • Inverting an Xfo with non-uniform scale now correctly rotates the scale values. (dda2d24)

3.6.1 (2021-11-02)​

Bug Fixes​

  • False positives in the Geom hashing in the GeomLibrary let to cracks and incorrect geoms being assigned in the zcad file. (00e89de)

3.6.0 (2021-10-06)​

Features​

  • The engine now supports exporting zcad files that contain non-orthogonal and uniform scaling within the tree. (0f0f737)

Bug Fixes​

  • Bodies containing multiple similar materials did not optimize correctly. (e57edfa)
  • During export, bounding box calculation code to filter unused vertices caused a performance issue resulting in long pauses exporting large meshes. This has now been addressed. (06ad102)
  • Fixed bug causing GeomLibrary hashing to miss cases where geoms were identical. (59acd38)
  • Quat.setFromMat3 is now more relaxed about detecting orthogonality, as it was throwing false negatives. (9211231)

3.5.2 (2021-08-13)​

Bug Fixes​

  • Bounding box calculation now filters out non-indexed points. This ensures the bounding box tightly frames on the actual rendered geometry. (70323bb)

3.5.1 (2021-07-23)​

Bug Fixes​

  • During export GeomItem now calculates the precise bounding boxes in global space, and then back transforming them into the space of the GeomItem. (d28f2ff)
  • Geometry compression makes more iteractions and more accurately compresses geometries with higher precision settings. This addresses issues where edges would display jaggies when loaded in the browser. (d66d3c3)
  • Geometry hashing more thoroughly checks if geometries match. (b4d152c)
  • To address false positives in geometry comparisons, GeomLibrary now takes an explicit 'tolerance' value. (870daad)

3.5.0 (2021-07-16)​

Features​

  • add constructor to FilePath taking a std::experimental::filesystem::path so that it is possible to pass a fully constructed path. (b961f14)
  • Added support for StringList property. A property that stores an array of strings. (617088f)
  • Implmeneted Mesh.setFaceVertexIndex to modifiy the stored mesh topology. (6458c40)
  • kmeans compression now adapts the number of clusters during compression to achiever the best balance of quality over efficiency. (5c99fae)

Bug Fixes​

  • Addressed issue normalizing geometries which were 2 point lines on certain orientations. (57e276f)
  • Addressed warning message when encoding files using relative file paths, (9b62598)
  • Cleaned up regressions on Linux in FileSystem::currentWorkingDirectory and FileSystem::changeCurrentWorkingDirectory. Reverting back to previous implementation. (92d9d67)
  • FilePath now uses the std::filesystem::path as its internal representation instead of std::string. This provides better support for internationalization of filenames and paths. (a0300be)
  • ZeaArchive code to cleanup old files reverted back to previous implementation that uses just the filename. (292d96d)

3.4.1 (2021-04-27)​

Bug Fixes​

  • path concatenation now works when the path contains multi-byte characters. (fb62267)

3.4.0 (2021-04-19)​

Features​

  • Any TreeItem can now be optimized, where the subtree is reduced to a single geometry when possible. (d11d5bb)
  • Geometries support more types of Vertex Attributes (SInt32, SInt32, Float32.... Needed by SimStream) (23d3c56)
  • GeomLibrary now uses an acceleration structure to speed up adding many geoms to the library. (f3fa436)

Bug Fixes​

  • ZeaArchive now correctly finds the archiver.exe if it is in the current folder or parent folder. (97560c5)

3.3.0 (2021-02-12)​

Features​

  • Cleaned up Fbx Parser. Now Fbx files are parsing again. (47b4891)
  • GeomItem now export Geom BoundingBox so that we can build the bounding box tree before the geom is loaded. Required to support streaming geoms. (83f26c0)
  • GeomLibrary now generated a JSON file along with the binary geom files during export. (6521c49)
  • ZeaArchive files now take an optional 'opts' argument for specifying compression params. (009916b)

Bug Fixes​

  • FilePath concatenation now automatically adds a separator to the parent path if none already exists. Addresses issues where an invalid path was generated. (75ffe50)
  • Fixed crash parsing files where names were not unique, and included a string of numbers at the end of the name. (d15a9bf)
  • Improved geom hashing on regular meshes. Increases hashing efficacy by up to 90% (6617a2e)
  • the EXPORT_FLAG_EMBEDGEOMS flag was being erroneously checked. (d2821f6)

2.0.0​

Bug Fixes​

  • Fixed issues with merging lines and points geometries.

1.1.0​

Features​

  • addition of edges to the description of each CAD body.
  • Implemented higher precision surface trimming implementation that reduces artifacts on holes, especially in corners.

Bug Fixes​

  • Addressed bugs addressed relating to the processing of curves.
