* Update eigen from v3.3.7 to v5.0.1.
This updates eigen from v3.3.7 released on December 11, 2018-12-11 to v5.0.1
released on 2025-11-11. There have be a large number of bug-fixes,
optimizations, and improvements between these releases. See the details at;
https://gitlab.com/libeigen/eigen/-/releases
It retains the previous custom minimal `CMakeLists.txt`, and adds a
README-OrcaSlicer.md that explains what version and parts of the upstream
eigen release have been included, and where the full release can be found.
* Update libigl from v2.0.0 (or older) to v2.6.0.
This updates libigl from what was probably v2.0.0 released on 2018-10-16 to
v2.6.0 released on 2025-05-15. It's possible the old version was even older
than that but there is no version indicators in the code and I ran out of
patience identifying missing changes and only went back as far as v2.0.0.
There have been a large number of bug-fixes, optimizations, and improvements
between these versions. See the following for details;
https://github.com/libigl/libigl/releases
I retained the minimal custom `CMakeLists.txt`, added `README.md` from the
libigl distribution which identifies the version, and added a
README-OrcaSlicer.md that details the version and parts that have been
included.
* Update libslic3r for libigl v2.6.0 changes.
This updates libslic3r for all changes moving to eigen v5.0.1 and libigl
v2.6.0. Despite the large number of updates to both dependencies, no changes
were required for the eigen update, and only one change was required for the
libigl update.
For libigl, `igl::Hit` was changed to a template taking the Scalar type to
use. Previously it was hard-coded to `float`, so to minimize possible impact
I've updated all places it is used from `igl::Hit` to `igl::Hit<float>`.
* Add compiler option `-DNOMINMAX` for libigl with MSVC.
MSVC by default defines `min(()` and `max()` macros that break
`std::numeric_limits<>::max()`. The upstream cmake that we don't include
adds `-DNOMINMAX` for the libigl module when compiling with MSVC, so we need
to add the same thing here.
* Fix src/libslic3r/TriangleMeshDeal.cpp for the unmodified upstream libigl.
This fixes `TriangleMeshDeal.cpp` to work with the unmodified upstream
libigl v2.6.0. loop.{h,cpp} implementation.
This file and feature was added in PR "BBS Port: Mesh Subdivision" (#12150)
which included changes to `loop.{h,cpp}` in the old version of libigl. This PR
avoids modifying the included dependencies, and uses the updated upstream
versions of those files without any modifications, which requires fixing
TriangleMeshDeal.cpp to work with them.
In particular, the modifications made to `loop.{h,cpp}` included changing the
return type from void to bool, adding additional validation checking of the
input meshes, and returning false if they failed validation. These added
checks looked unnecessary and would only have caught problems if the input
mesh was very corrupt.
To make `TriangleMeshDeal.cpp` work without this built-in checking
functionality, I removed checking/handling of any `false` return value.
There was also a hell of a lot of redundant copying and casting back and forth
between float and double, so I cleaned that up. The input and output meshs use
floats for the vertexes, and there would be no accuracy benefits from casting
to and from doubles for the simple weighted average operations done by
igl::loop(). So this just uses `Eigen:Map` to use the original input mesh
vertex data directly without requiring any copy or casting.
* Move eigen from included `deps_src` to externaly fetched `deps`.
This copys what PrusaSlicer did and moved it from an included dependency under
`deps_src` to an externaly fetched dependency under `deps`. This requires
updating some `CMakeList.txt` configs and removing the old and obsolete
`cmake/modules/FindEigen3.cmake`. The details of when this was done in
PrusaSlicer and the followup fixes are at;
* 21116995d7
* https://github.com/prusa3d/PrusaSlicer/issues/13608
* https://github.com/prusa3d/PrusaSlicer/pull/13609
* e3c277b9ee
For some reason I don't fully understand this also required fixing
`src/slic3r/GUI/GUI_App.cpp` by adding `#include <boost/nowide/cstdio.hpp>` to
fix an `error: ‘remove’ is not a member of ‘boost::nowide'`. The main thing I
don't understand is how it worked before. Note that this include is in the
PrusaSlicer version of this file, but it also significantly deviates from what
is currently in OrcaSlicer in many other ways.
* Whups... I missed adding the deps/Eigen/Eigen.cmake file...
* Tidy some whitespace indenting in CMakeLists.txt.
* Ugh... tabs indenting needing fixes.
* Change the include order of deps/Eigen.
It turns out that although Boost includes some references to Eigen, Eigen also
includes some references to Boost for supporting some of it's additional
numeric types.
I don't think it matters much since we are not using these features, but I
think technically its more correct to say Eigen depends on Boost than the
other way around, so I've re-ordered them.
* Add source for Eigen 5.0.1 download to flatpak yml config.
* Add explicit `DEPENDS dep_Boost to deps/Eigen.
I missed this before. This ensures we don't rely on include orders to make
sure Boost is installed before we configure Eigen.
* Add `DEPENDS dep_Boost dep_GMP dep_MPFR` to deps/Eigen.
It turns out Eigen can also use GMP and MPFR for multi-precision and
multi-precision-rounded numeric types if they are available.
Again, I don't think we are using these so it doesn't really matter, but it is
technically correct and ensures they are there if we ever do need them.
* Fix deps DEPENDENCY ordering for GMP, MPFR, Eigen, and CGAL.
I think this is finally correct. Apparently CGAL also optionally depends on
Eigen, so the correct dependency order from lowest to highest is GMP, MPFR, Eigen, and CGAL.

Port Z Anti-Aliasing from BambuStudio-ZAA (https://github.com/adob/BambuStudio-ZAA)
to OrcaSlicer. ZAA eliminates stair-stepping on curved and sloped top surfaces
by raycasting each extrusion point against the original 3D mesh and micro-adjusting
Z height to follow the actual surface geometry.
Key changes:
- Add ContourZ.cpp raycasting algorithm (~330 lines)
- Extend geometry with 3D support (Point3, Line3, Polyline3, MultiPoint3)
- Template arc fitting for 2D/3D compatibility
- Change ExtrusionPath::polyline from Polyline to Polyline3
- Add 5 ZAA config options (zaa_enabled, zaa_min_z, etc.)
- Add posContouring pipeline step in PrintObject
- Update GCode writer for 3D coordinate output
- Add ZAA settings UI in Print Settings > Quality
- Add docs/ZAA.md with usage and implementation details
ZAA is opt-in and disabled by default. When disabled, the slicing pipeline
is unchanged.
* Add read support for Google's Draco (.drc) format.
* Fix build on Linux
* Use boost instead of fstat.
* Switch to boost memory-mapped file to save RAM and potentially improve performance.
* Trim trailing whitespace.
* Initial Draco write support.
Currently always exports with 16-bit precision and speed 0 (best compression).
The back-end function does have arguments to specify them, it's just not hooked into the GUI.
* Add Draco to the About dialogue.
* Fix Linux compile (hopefully)
* Add an option to associate DRC files on Windows.
* Implement a Preferences option to set Draco position quantization bits
* Update src/slic3r/GUI/Preferences.cpp
Co-authored-by: Ian Bassi <ian.bassi@outlook.com>
* Some slight changes to ianalexis's suggestion.
* Implement a create_item_spinctrl() function for numeric inputs, and use that instead of create_item_input().
* Move "bits" to inside the spinctrl box.
* Refactor following yw4z's feedback
* Update src/slic3r/GUI/Preferences.cpp
Co-authored-by: Ian Bassi <ian.bassi@outlook.com>
* Change to 0 bits as the default setting for Draco export precision.
* Change to a lossy checkbox and a bits field with a range of 8-30.
* Proper SpinInput code from yw4z
* Revert "Proper SpinInput code from yw4z"
This reverts commit 7e9c85f31a.
* Revert "Change to a lossy checkbox and a bits field with a range of 8-30."
This reverts commit d642c9bcc0.
* Redo preferences based on SoftFever's feedback
* Refactor to minimize code duplication
* Fix padding
* Improve Draco export quality level tooltip clarity
Clarify that 0 means lossless compression (not uncompressed),
document the valid lossy range (8-30), and better explain the
tradeoff between file size and geometric detail.

Especially in cases when the object is composed only of 2 external perimeters and 1 or 2 internal perimeters, the order of perimeters wasn't optimal and differed from the Classic perimeter generator. That caused unnecessary long travels before the external contour was printed.
The ordering of perimeters is slightly inspired by the latest changes in CuraEngine.
