Apparently B-Spline knot insertion is challenging the sketcher update process
and spurious GUI updates sometimes occur in the intermediate step after the
knot is inserted but before the internal geometries are re-defined. This set of
comments points to a previous fix and related discussion as a suggestion.
==============================
- Constructor from const vector reference is not allowed to take ownership (as it should not delete the const pointer). The ownership parameter is removed.
- Factory method for const objects cannot either. So the ownership parameter is also removed.
=====================================
- GeometryFacade will throw when instantiated with a const Part::Geometry * that does not have a SketchGeometryExtension. It
cannot create it because it is not supposed to modify a pointer to a const object.
- Static functions will check the passed Part::Geometry * parameters and will throw if nullptr.
- GeometryTypedFacade constructor and factory methods to take owner parameter (defaulted to false) for consistency with GeometryFacade.
- The emplace style factory method will make the GeometryFacade take ownership of the emplaced Part::Geometry *. This should avoid memory leaks. The
user shall setOwner(false) if it needs to release() the underlying Part::Geometry * (to transfer ownership).
- Code comments made into doxygen documentation.
=================================================================================
Apart from simplifying code, the allocated memory is not managed by the lifetime of the unique pointer owned by the GeometryFacade, preventing memory leaks.
================================================================================
GeoEnum static members are used in constexpr in GeoListId.
Previous code worked because the static members where inside the same translation unit.
This code:
1. Declares the static members to use them as constant expressions with the value
2. Definition of the static members (odr-used) shall not contain an initializer.
When new control points are created in a b-spline in a sketch, do not constrain
their weights to be equal to the first, unless they are already equal. This way
if we have unequal weights to begin with and OCC has computed the appropriate
weights so that the new spline is closer to the original, the weights are not
disturbed.
==============================
- Improve GeoList to support GeoElementId input
- Support VertexId to GeoElementId conversion
- GeoListModel gets separate getGeometry and getGeometryFacade naked pointers
- Sketcher: GeoList - make index mappings mutable
- Improve documentation
===================================================
This commit is an independent refactor of the identifications used at Sketcher level.
It introduces a new type "GeoElementId" as a combination of GeoId and PointPos.
It moves the Undefined GeoId, previous Constraint::GeoUndef to GeoEnum, together with all
other fixed values of GeoIds.
========================================================================
As GeometryFacade is provided with more sketcher specific functionality, the demand
for to get GeometryFacades instead of Part::Geometry object increases too. This
addition reflects this increase of demand.
==============================================
Separate struct into own file to avoid having to include all the dependencies of SketchObject in other code that relies on GeoEnum.
==============================
Class for managing internal and external geometry as a single object. This is a light-weight alternative to
passing the whole SketchObject.
It reflects the format used in getCompleteGeometry of SketchObject and Sketch solver facade class, while providing
several convenient conversion functions to map indices.
Internal and external geometries are present in a single geometry vector one after the other.
The index of the geomlist (all layers) and the GeoId can be converted from each other at needed
using the member fuctions (and sometimes the static member functions).
Internal implementation is as a template GeoListModel<T>.
The following types are instantiated. Specialisation is provided where necessary.
GeoList = GeoListModel<Part::Geometry *>;
GeoListFacade = GeoListModel<std::unique_ptr<const Sketcher::GeometryFacade>>;
This enables to use the lighter GeoList were sufficient, while enabling off-the-shelf replacement
when switching to a GeoListFacade is necessary.
LGTM complains about using continue statements inside a loop
whose condition is always false. In addition, the C++ core guidelines
recommend against using the do...while construct, and in this case it
was really serving as a goto, just hiding the actual goto keyword.
This commit replaces the loop and continue structure with simple
conditionals.
=============================================
This commit is directed to external functionality of the split() function.
1. getAppliedConstraints renamed to getConstraintIndices
This is just for clarity being a general function
2. SwapInvolvedGeometry functionality moved to Constraint class
Why?
i. Because it is a specific operation on a constraint, it must not be
a public function, as it does not define interface of the Sketch.
ii. It could be a lambda or a private utility function, but them it would not be reusable.
iii. It could be part of a helper class, but then, it is would be less reusable.
3. renaming of the flag passed to transferConstraints function
======================================
* Refactor the code for all GeomTrimmedCurve and non-periodic BSplines in a single block, adding
support for arcs of hyperbola, parabola and B-Splines.
* Refactor the code for periodic curves (circle, ellipse) in a single block, adding support for
periodic B-Splines.
* Add support for trimming limited by external geometry
* Trim deletes a geometry if intersections are detected and nothing would be left after trimming
* Trim deletes a geometry if no intersection are detected
Bonus:
* Function addConstraint moving the constraint instead of cloning it again
* SketchObject::seekTrimPoints as a wrapper of Part2DObject::seekTrimPoints providing
a correct handling of GeoId indices.
* Helper functions addConstraint/createconstraint to create new constraints and move them
into the Constraint property
* New getGeometry with templated return type defaulting to Part::Geometry.
