The algorithm that builds outlines ("silhouettes") makes an outline in 2d parametric space of the surface starting from some previously detected point where normal is orthogonal to direction of view. So, the surface is previously discretized into (m*n) sample points and some of them become starting points for future outlines.
If the surface has non-uniform parametrization and/or some local extremums of curvature, the outlines can not be built without breaks, so there are several groups of consequent outlines in this case. Unfortunately, it leads to the situation when current number of sample points becomes insufficient to build all the parts of outlines.
The idea is to detect the "holes" between already constructed parts of outlines and then complete the construction.
New auxiliary draw command for testing of HLR.
Correction according to the remarks.
Update of test case according to the developer's directive
Useless *.cxx files were removed to eliminate linker warning LNK4221.
Package TopOpeBRepDS was cleaned up from old debugging routines.
Merged OSD_signal_WNT.cxx into OSD_signal.cxx
Class Standard_ErrorHandlerCallback was moved into the Standard_ErrorHandler class as nested class Callback
Eliminated warning about unused variable.
1. The reason of the regression is not-closed intersection result. This problem has been solved (in this fix) by adding joint point to the both neighbors intersection lines (lines were extended to the this intersection point). It is made in IntPatch_WLineTool::ExtendTwoWlinesToEachOther(...) method.
2. Interface of IntPatch_PointLine and inherited classes has been changed. Methods ChangeVertex(...) and RemoveVertex(...) have been added.
Test cases for this issue have been created.
Small correction in the code.
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
1. Function IsSame(...) for IntSurf_PntOn2S was added (see IntSurf_PntOn2S.cdl for detail information).
2. Inserting additional points is forbidden if existing WLine contains only two points coincided.
Test-case for issue #25488
Redundant keyword 'mutable' removed in CDL files.
In IGESConvGeom_GeomBuilder, unused methods MakeXY() and MakeXYZ() removed.
Method StepAP214_AutoDesignGroupAssignment::Init() replicating same method of the base class is removed as it causes CDL extraction error after above (seemingly irrelevant) changes.
License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.
Modifications:
1. The validity of the intersection point between edge and face is checked with sum of the tolerance values of the edge and face.
2. The intersection between toroidal surface and one of the following surfaces: Plane, Cylinder, Sphere, Cone or Torus
is treated as analytical in the following cases:
1) Torus and Plane: a. Axes of the surfaces are parallel;
b. Axes of the surfaces are perpendicular and location of the torus is lying on the plane;
2) Torus and Sphere: The location of the sphere is lying on the line made from toruses axis;
3) Torus and Cone, Cylinder or Torus: The axis of the surfaces are collinear.
In all cases the intersection line(s) is(are) circle(s).
Added test cases bugs/modalg_5/bug24470
The intersection between torus with minor radius more than (or equal to) the major radius and any other surface is considered as parametric.
