- Added GridGeneration-Geometries-3D-CreateTKD
- Added GridGeneration-Geometries-3D-CreateTKDWithOuterLayer
Fixes:
- Autoassigning accidentally unassigned elements after, e.g., TriangleFill,
Retriangulate, AdjustEdgeLenght, Tetrahedralize, etc.
-------------------------------------------------------------------------------
v 4.3.9
Changes and additions:
- Remeshing-Orientation-AdjustEdgeOrientation now only considers the set of
selected faces.
- Tetgen is now used as a separate process through a file-interface
- Support for *.swc files added
- Action-Log added
Fixes:
-------------------------------------------------------------------------------
v 4.3.8
Changes and additions:
- Added a separate CoordinateWidget (formerly CoordinateTransform-Coordinates)
- Added shortcuts for selection-element-type and selection-mode (keys 1-7)
- If a tool is executed but no object exists yet, a new object will be created
automatically before the tool is applied.
- Added CoordinateTransform-Mirror
- Changed registration procedure of tools. Tools ordering is now different to
previous versions.
- All coordinate input boxes now have a coherent design and accept text input
- New shortcuts for Collapse (Merge), SplitEdge, SwapEdge, Refine.

Fixes:
- Background color is now stored in a different way to avoid some problems on
some systems
-------------------------------------------------------------------------------
v 4.3.7
Changes and additions:
- After Remeshing-PlaneCut, only new edges along the cut are selected now.
- Added ProjectToLayers and ProjectToTopLayers to the scripting backend.
- Added Selection-CoordinateRange tools
Fixes:
- Boolean operations now work if multiple subsets exist
- Fixed default values in tool dialogs
-------------------------------------------------------------------------------
v 4.3.6
Changes and additions:
- Added subset based boolean operations for CSG modeling
(Union, Intersection, Difference)
- Added 'AssignSubset' and 'AssignNewSubset' to the SceneInspectors R-Click Menu
- Preparations for different Views
Fixes:

-------------------------------------------------------------------------------
v 4.3.5
Changes and additions:
- Speed up when visibilities are changed in the SceneInspector
(removed undo-points here)
Fixes:
- Face orientation during 3d extrusion is now preserved.
- Added a warning for faces with unsupported numbers of vertices in .obj loading.
-------------------------------------------------------------------------------
v 4.3.4

Fixes:
-------------------------------------------------------------------------------
v 4.3.3
Changes and additions:
- Adjusted draw-color of edges, so that they are always slightly different from
the draw-color of faces.
- Fixed z-Buffer artifacts on Windows
Fixes:
-------------------------------------------------------------------------------
v 4.3.2
Changes and additions:
- Internal adjustments to better support attachment serialization and
deserialization.
- A RasterLayersProjector can now be generated along with a layered geometry and
used during refinement. It will also be exported to .ugx files.
- Draw Path: Instead of using CTRL one now places vertices by pressing the key 'V'
- Camera: Camera may now be moved by holding CTRL again.
Fixes:
-------------------------------------------------------------------------------
v 4.3.1
Changes and additions:
- Added options-panel

v 4.3.0
Changes and additions:
- New interface design (dark theme).
- Refinement projectors can now be specified per subset. During refinement they
can transform the geometry in different ways (e.g. to better approximate some
smooth boundary description). Projectors can be applied to any subset and should
behave correctly even for inner manifold subsets in volume geometries
(e.g. inner boundaries).
- Current projectors:
* Default (inserts vertices at midpoints of parent elements)
* Sphere (with optional influence radius)
* Cylinder (with optional influence radius)
* Smooth (Laplacian smoothing)
* Subdivision (Loop subdivision)
- ugx Files now support refinement projectors.

more varied refinement schemes.
Fixes:

display lists to the selection list only.
Fixes:
-------------------------------------------------------------------------------
v 4.2.7
Changes and additions:
- Further improvements to subset-assignment in ExtrudeLayers. Total layer
height at each vertex is now the deciding factor during assignment.
Fixes:
-------------------------------------------------------------------------------
v 4.2.6
Changes and additions:

deciding on the assignment.

Fixes:
-------------------------------------------------------------------------------
v 4.2.4
Changes and additions:
- Added tools to buffer and to restore vertex coordinates:
* CoordinateTransform-CoordinateBuffer-StoreVertexCoordinates
* CoordinateTransform-CoordinateBuffer-RestoreVertexCoordinates
Those tools are useful if one wants to alter subset-assignments but requires
to transform the grid temporarily to do so.
- Added a tool
* Subsets-AssignNewSubset
which automatically chooses the subset index as #subsets
Fixes:
- ugx reading is now more robust regarding vertex specification.
- Fixed an issue in 'Remeshing-Polylines-SimplifyPolylines' where some vertices
hadn't been removed even though they obviously should have been removed.

Changes and additions:
- .tex export now sorts elements before writing the output. Subset-Names are
now used to identify styles instead of subset indices.
An optional style-file 'custom_promesh_style.tex' is now optionally included
by the resulting .tex file. This allows users to override the default style
on a per-subset basis.
- *.smesh files can now be loaded through File->Open. 'smesh' is a format defined
by 'tetgen'.
Fixes:
- Fixed a bug which sometimes occurred in ExtrudeLayers when 'allow for tets and pyras'
was enabled.
-------------------------------------------------------------------------------
v 4.2.2
Changes and additions:
- CTRL+RightMouseClick now selects the whole subset independent of the current
selection mode.
Fixes:

-------------------------------------------------------------------------------
v 4.2.1

- Tool Subset-AssignSubset now allows to assign selected vertices/edges/faces/volumes only
- RasterLayers now support a separate min-height for each layer
Fixes:

- Improved Delaunay-Refinement by adding support for circular-shells and off-centers.
Fixes:
- ToolBrowser now adapts to new/changed/erased scripts nicely.
- Zoom-in can now be performed until rounding-errors are visible.
(distance to focus point is now considered too to compute near-clipping plane)
- Fixed special cases in delaunay-triangulation and delaunay-refinement used in
Triangulate and Retriangulate
- Subsets-CopySubsetIndicesToSides: Subsets of lower dimension are now treated
with a higher priority than subsets with higher dimension.
- Disabled strict subset inheritance. Edges created through splits or refinement
will now be assigned to the subset of the orignial face.
- Fixed crash in Retretrahedralize
- CollapseEdge now also supports Pyramids and Prisms (note that new volume elements
can only be created for some of the possible collapse-constellations)
- MergeVertices now handles quadrilaterals, prisms, and pyramids more gracefully.
As also seen in CollapseEdge, there are collapse-constellations for which it is not
possible to create new volume elements from affected prisms and/or pyramids.

when triangles outside the remeshing region were in a completely different
plane than the remeshing zone itself.
- Tetrahedralization now automatically removes vertices which are not connected
to any edge or face. This was required since tetrahedralization may not terminate
with such vertices present and since a user may have a hard time to find them
(or to remember to remove them).
