v1.9.7

Note: the packages generated by github (Source code links) do not contain the submodules. Use geogram-1.9.7.tar.gz or geogram-1.9.7.zip instead to get everything.

What's Changed

• attributes now support types that do dynamic allocation
• OpenNL is now a submodule (and has its own repository here)
• CSGBuilder: Improved OpenSCAD compatibility
• CSGBuilder: refactoring, preparing for tree transformers (optimization at the AST level)
• CSGCompiler: fixed a (rather ridiculous) performance bug: the function to display current line was traversing the whole buffer each time. Just logging progress was costing O(N^2) !!
• Fixes in legacy code for gcc15 (thank you Cedric Borgese)

Full Changelog: v1.9.6...v1.9.7

v1.9.6

Note: the packages generated by github (Source code links) do not contain the submodules. Use geogram-1.9.6.tar.gz or geogram-1.9.6.zip instead to get everything.

What's Changed

• Rewrote many functions using new Mesh "syntaxic sugar" functions (both easier to read and faster)
• New AABB_INDIRECT mode for MeshAABB (uses a vector of indices instead of permutting mesh-elements in-place)
• mesh_reorder: new function to compute spatial ordering of mesh elements in a vector of indices
• Minor fixes and improvements in MeshCSG
• Transparent rendering mode for geogram_demo_Evert
• compute_CSG: Clearer display of timing breakdowns in verbose mode
• Fix for CLion on Windows by @tksuoran in #256
• Fixes for linking problems when accessing static class members outside DLL under Windows
• ExactCDT::create_enclosing_triangle()
• VSA L12 segmenter: changed default anisotropy value (made it larger). Works better with scanned meshes
• DevOps: test results, Emscripten compilation now generated in separate repositories (geogram.CI and geogram.run). Doxygen documentation still generated here.

Note: the packages generated by github (Source code links) do not contain the submodules. Use geogram-1.9.5.tar.gz or geogram-1.9.5.zip instead to get everything.

What's changed

• syntaxic sugar, easier iteration on Mesh elements and direct access to points (note: some functions in mesh_geometry.h declared as deprecated will be removed in next release).
• Application::snapshot() function to save images
• Improved OpenSCAD compatibility in MeshCSG (same sphere discretization as OpenSCAD)
• Several fixes in geogram_gfx lib for MacOS (mouse handler, taking into account retina screens
• Delaunay now uses unsigned integers instead of signed integers
• Fixed an annoying bug in GEO::Application (recursive redraw triggered by recursive event handler)
• WIP: GLUP140 profile for OpenGL 4.1 (will replace the GLUPES profile)

• support for very large meshes (> 4Gb) in .geogram file format, both in standard and GARGANTUA mode
• interoperability between .geogram files saved in standard and in GARGANTUA mode
• adapted to new DearImGui v1.91.8 (default transparency has changed for color buttons, and format for serialized layout has changed)
• new PolyScope color scheme (shamelessly copied)
• improved compatibility of CSG engine with OpenSCAD.
• fixed annoying bug that was due to printing to Console triggering graphic update, even when called from event handler

• geogram_gfx bugfix: lines of width 1 are not clipped under GLUP_140 and GLUP_440 profiles
• geogram feature: POSIX stack trace in logs (Linux and MacOS), facilitates a lot bug hunting in continuous integ platform
• PSMs: Delaunay PSM and multiprecision PSM: fixed compilation problem (due to new std::atomic<> based thread sync)
• portability: Rewrite of thread sync mechanism using std::atomic and std::condition_variable
