geogram - v1.8.8 Latest Release

Published by BrunoLevy 9 months ago

Note: the packages generated by github (Source code links) do not contain the submodules. Use geogram_1.8.8.tar.gz or geogram_1.8.8.zip instead to get everything.

Fixed a small GLSL bug that prevented thick lines shader to compile with some OpenGL drivers (see #54).

geogram - v1.8.7

Published by BrunoLevy 9 months ago

Note: the packages generated by github (Source code links) do not contain the submodules. Use geogram_1.8.7.tar.gz or geogram_1.8.7.zip instead to get everything.

What's new

mesh intersection: speed improvement
mesh intersection: simplify coplanar facets
mesh intersection: facet corner attribute interpolation
mesh subdivision: attribute interpolation
new Open-SCAD compatible MeshCSG
geogram_gfx: thick lines
using C++ number generator (@weynaa) fixes a problem when remeshing large meshes
clang-16 fix "implicit int" errors in legacy code (@daichi-ishida)
Attribute: generic interpolation function

Note geogram_gfx thick lines shader cannot be compiled by some OpenGL drivers. Problem fixed in v1.8.8, to be released super soon if not already there, else get v1.8.8-rc from repository (the fix was pushed).

geogram - v1.8.6

Published by BrunoLevy 12 months ago

Note: the packages generated by github (Source code links) do not contain the submodules. Use geogram_1.8.6.tar.gz or geogram_1.8.6.zip instead to get everything.

Note: Some PSMs (Multiprecision, Predicates and Delaunay) are broken in this release. If you need PSMs you can either generate them from v1.8.6-rc in the repo (see tools/make_geogram_dist) or use the ones from v1.8.5 (there was not much change in these functionalities). This only concerns users that use only the subset of geogram in these PSMs. Users that use the full geogram library are not concerned.

What's new: many improvements and bug fixes in mesh intersection and mesh boolean operations

Test suite for mesh intersection.
New generic geometric types: vectors in 2D and 3D with homogeneous coordinates.
Intersection code that works with bundled expansion-based arithmetic kernel or Tessael's geogram-plus high performance rugged arithmetic kernel.
New interval arithmetics and predicates filtering for mesh intersection.
Improvements in expansion arithmetics.
Fixed stack overflow problems under MacOSX and Windows when allocating too many expansions on stack.
