The method to find common Vertices and Edges between faces
BRepOffset_Tool::HasCommonShapes(const TopoDS_Face&,
const TopoDS_Face&,
TopTools_ListOfShape&,
TopTools_ListOfShape&)
has been re-implemented using maps and renamed to BRepOffset_Tool::FindCommonShapes.
The new method
BRepOffset_Tool::FindCommonShapes(const TopoDS_Shape&,
const TopoDS_Shape&,
const TopAbs_ShapeEnum,
TopTools_ListOfShape&)
has been implemented to look for the common shapes of given type.
1. Correct building of the lists of intersection faces connected to the same vertex.
2. For the artificially invalid cases with only one invalid face avoid usage of the edges having same origins as invalid edges.
3. Test cases for the issue.
4. Test cases offset shape_type_i_c XM1, ZW*,ZX*,ZY* have been modified to provide more clear result.
5. TODO statements have been removed from the test case offset shape_type_i_c XE6 as it is OK.
6. Test case offset shape_type_i_c ZZ2 is improvement.
1. BRepOffset_Inter3d::ConnexIntByInt
Create unique offset edge for each localized part shared between pair of faces of the input shape.
2. Test cases for the issue.
Extension on the 3D Offset algorithm (Mode="Complete", Join Type = "Intersection")
for colliding cases to add support for new configurations of the shapes.
In the previous approach the result of the offset operation was build from
the offset faces using MakerVolume algorithm, without checking of the validity of these faces.
The new extension is based on this approach, but now the offset faces are being checked
on invalidity and rebuild in case of any. This allows (in case of successful rebuilding) to avoid creation
of the unforeseen parts such as dangling parts, spikes, inverted faces in the result of offset operation.
The main criteria for the validity of the faces is the coincidence of the normal
direction of the offset face with the normal direction of the original face.
Check for removal of invalid faces has been removed as obsolete.
BRepOffset_Inter2D: Avoid excess trimming of the edges due to coincidence with other edges.
BRepOffset_Inter3D: Careful treatment of the intersection of the faces connected only through vertices.
Eliminating the compiler warning.
Small corrections of test cases for issue CR26917
Automatic upgrade of OCCT code by command "occt_upgrade . -nocdl":
- WOK-generated header files from inc and sources from drv are moved to src
- CDL files removed
- All packages are converted to nocdlpack
Sometimes curve or surface, which is defined as C0, has continuity G1 or above. Offset can be built from these shapes.
Therefore, this extended checking was added into SetBasisCurve and SetBasisSurface methods.
Main changes in function BRepOffset_Tool::ExtentFace(...):
* "return" is added if intersection (in 2D-space) between two edges in a face cannot be found.
Basis curve/surface continuity value found (if G1-checking is OK) is set up as BasisContinuity (see myBasisCurveContinuity and myBasisSurfContinuity members which is returned by GetBasisCurveContinuity and GetBasisSurfContinuity() methods). This fact is used in Geom2dAdaptor and in GeomAdaptor classes.
Possibility is entered, which allows for basis elements of offset curve/surface to avoid of C0-checking.
Test cases were changed according to their new behavior.
