The main idea of the fix is to forbid check if intersection curve lies in the some face (with input tolerance) if we have 2D-intersection curve on this face (we consider that necessary tolerance has been computed in intersection algorithm honestly). If we do not have 2D-curve on this face then we need check as before.
New algorithm is implemented in IntTools_Context::IsValidBlockForFaces(...) method.

src\Extrema\Extrema_GenExtPS.cxx
No principled changes have been made.
Virtual method Generated is redefined. Now it returns:
- chain of generated faces for sub-edge of a profile;
- chain of generated edges for sub-vertex of a profile;
- bunch of chains of generated edges for start or end vertex if it is degenerated section.
Correction according to the remarks.
Fix compiler's warnings and add 4 new test cases.
Correction of mistake.
Compilation warnings are gone.
Graphic3d_RenderingParams::RenderResolutionScale - added new option
defining scale factor for allocating off-screen rendering buffers
relative to native resolution of window buffer.
Scale factor can be below 1.0 (lower resolution) or higher (as analog of super sampling),
but can not be combined with MSAA settings.
Draw Harness command vrenderparams has been extended with option -rendScale
managing introduced option Graphic3d_RenderingParams::RenderResolutionScale.
vcaps has been extended with option -useWindowBuffer for managing
OpenGl_Caps::useSystemBuffer option.
vrepaint has been extended with option -immediate
for testing immediate layer redraw
OpenGl_View::blitBuffers() - eliminate compiler warning on Android
Existing OCCT path tracing engine used very simple additive material (BSDF) model, so it was possible to reproduce
behavior only of very basic materials such as metal, glass, or plastic. However, some important in CAD industry
materials like car paint or ceramic could not be modeled well. In this patch, OCCT BSDF was significantly improved
by replacing additive model with two-layered scattering model. Therefore, we have base diffuse, glossy, or transmissive
layer, covered by one glossy/specular coat. The layers themselves have no thickness; they can simply reflect light or
transmits it to the layer under it. Balancing different combinations of layer properties can produce a wide range of
different effects. At the same time, disabling the first (coat) layer allows to keep full compatibility with previously
supported scattering model. All new parameters are available via 'vbsdf' command.
Location of new sample for few material examples:
samples\tcl\pathtrace_materials.tcl
Fix shader compilation issue.
Fix test case sample_ball_alpha.
Shaders_PathtraceBase_fs.pxx - regenerate resource from origin
Enumeration Image_PixMap::ImgFormat, previously declared as nested
enumeration within class *Image_PixMap*,
has been moved to global namespace as Image_Format following OCCT coding rules.
The enumeration values have suffix Image_Format_ and preserve
previous name scheme for easy renaming of old values.
E.g. Image_PixMap::ImgGray become Image_Format_Gray.
Old definitions are preserved as depreacated aliases to the new ones.
New method CheckFaceSelfIntersection has been added to BOPAlgo_CheckerSI: now self-intersection of each face is found as well as pairs of intersecting faces;
-method IntPatch_Intersection::Perform(S1,D1,TolArc,TolTang) is modified for more effective search of self-interasections in case of Surface Of Extrusion;
-method IntCurve_IntPolyPolyGen::Perform(C1,D1,TolConf,Tol,NbIter) is modified to detect segments of intersections.
Small correction.
Test cases are corrected.
Correction of compiler error
Fix of regressions
Names of shapes correction
1. For the support of the new configurations of the input shapes for the 3D offset algorithm
(shapes containing the faces with holes, which are growing during offset operation and
sometimes (depending on the offset value) even kill the faces themselves) the new function
*FindFacesInsideHoleWires* has been implemented. This new function looks for the splits of
the offset face located inside the new hole wire built from offset edges of the edges of the
hole wires of the original face. All found splits are simply removed.
2. Test cases for the issue.
Unit test and additional parsing rule for tests are added as well as a minor fix of the draw command for bug24164_2 unit test (in reference array it was impossible to set only one value).
Added the exception for the checking in issue 2269, when bad document is read.
It checks that there is no crash, but just an error message. If crash is appeared, this test will not skipped anyway.
Correction of test for bug2269 and parse.rules
1. The static method Standard_Real MinStep3D(...) in the class BOPTools_AlgoTools is
now checks if the computed 3D step is too big (relatively UV range of the faces)
for any of the faces.
2. The method PointInFace(...) of the class BOPTools_AlgoTools3D has been redesigned.
The new PointInFace(...) methods have been implemented to add possibility for looking the point
inside the face in necessary direction and distance from the edge of the face.
Note: old implementation is also functional.
3. Make methods for finding points near edges and computing normal directions on faces
return error status (0 in case of success).
4. Test case for the issue.
5. Test cases offset shape_type_i_c XJ2,XJ4,XJ5,XJ6 are improvements.
Removing useless file
1. The two new methods have been implemented:
a. BOPAlgo_Tools::EdgesToWires - allows creating planar wires from edges.
The input edges may be not shared, but the output wires will be sharing the coinciding vertices and edges.
It is possible to skip the sharing if the input edges are already shared by passing the corresponding flag into the method.
The input edges are expected to be planar, but the method does not check it. Thus, if the input edges are not planar, the output wires will also be not planar.
In general, the output wires will be non-manifold and may contain free vertices.
b. BOPAlgo_Tools::WiresToFaces - allows creating planar faces from the planar wires.
In general, the input wires are non-manifold and may be not closed, but should share the coinciding parts.
The wires located in the same plane and completely included into other wires will create holes in the faces built from bigger wires
These two methods combined allow building faces from set of edges randomly located in 3D space.
2. The DRAW command *edgestofaces* has been implemented.
3. The documentation has been updated with the new section in Modeling Algorithms - Topological Tools.
4. Test cases for the issue.
Added option ShapeFix_Solid::FixShellOrientationMode allowing to switch off analysis and fixing of orientations of shell(s) in solid.
Options FixVertexToleranceMode, FixShellOrientationMode, FixFaceOrientationMode are added to Shepe Processing resource file so that they can be manipulated.
Added new method Draw_Window::IsMapped() for checked window state.
Draw_Window using XLib now does not exit application on closing window.
The method Draw_Viewer::Select() (called by whatis command)
has been corrected so as not to enter the loop if no views are initialized.
The code of the methods BSplCLib::KnotForm and BSplCLib::MultForm has been made safe by giving up using of address of array item for iteration on the Array1. Also the checking for degenerated case has been added to prevent out of bounds exception.
Class DBRep_DrawableShape is changed to postpone generation of display data until the shape is actually displayed (for the first time).
Test perf draw bug28404 is added.
Macro NO_CXX_EXCEPTION was removed from code.
Method Raise() was replaced by explicit throw statement.
Method Standard_Failure::Caught() was replaced by normal C++mechanism of exception transfer.
Method Standard_Failure::Caught() is deprecated now.
Eliminated empty constructors.
Updated samples.
Eliminate empty method ChangeValue from NCollection_Map class.
Removed not operable methods from NCollection classes.
Useless writes of intermediate shapes to hardcoded paths are removed in samples\mfc\standard\02_Modeling\src\ModelingDoc.cpp
Methods IGESBRep::WriteShape(), XSControl_Utils::WriteShape() are deleted; BRepTools::Write() can be used instead.
Method TopOpeBRepBuild_Tools::DumpMapOfShapeWithState() is moved to where it is used -- TopOpeBRepBuild_Builder1_1.cxx as static function (commented out).
Unused DRAW command OCC18612 is removed.
Upgrade Guide is corrected to avoid Doxygen warnings.
1. The smarter conditions for removing the invalid faces with inverted edges have been implemented
(BRepOffset_MakeOffset::RemoveInvalidSplitsByInvertedEdges).
2. Avoid removed (completely inside) edges in the filtering of invalid faces
(BRepOffset_MakeOffset::FilterInvalidFaces).
3. Test cases for the issue.
The patch fixes transformation persistence for various set of GCC compilers.
1) Optimized template-specialized operator /= for division (causes bugs)
of NCollection_Vec4 was replaced with non-specialized version.
2) NCollection_Vec4::xyz() is not used since compiler uses modifiable-reference
returning version, which invokes warning of possible strict-aliasing rules
violation and leads to incorrect behavior of the reference.
If the line is in the circle-plane completely (or parallel to the circle-plane) then extremas and intersections in 2D-space are looked for. These case are pure analytical and solutions will be found precisely.
