c3cca01534 0028964: Draw - need to have command to apply ShapeFix_FixSmallFace tool
DRAW command fixsmallfaces is added to fix (remove) small faces in the shape.
Command OCC22586 is removed (replaced by fixsmallfaces).

Test bug28112_2 using that command is added for the two last shapes in issue #28112; test bug28112 is renamed to bug28112_1.
Test bug22586 is changed to use the new command.

8ae442a8cb 0028775: Code duplication removal across the BOPAlgo_PaveFiller algorithm
The methods PerformVerticesEE() and PerformVerticesEF() of the class BOPAlgo_PaveFiller have been replaced with the new PerformNewVertices() method.

While splitting the Pave Blocks with extra paves, check that the new Pave Blocks have the valid intersection range. If the new Pave Block does not have such range do not create it and unify its vertices making SD vertex.

Re-computation of the Shrunk Data for the modified Pave Blocks. The new method BOPDS_DS::IsValidShrunkData(const Handle(BOPDS_PaveBlock)& thePB) has been implemented to check that the Shrunk Data of the Pave Block is still valid. It may become invalid in case the tolerance values of the vertices of the Pave Block have been modified.

The test case bugs/modalg_6/bug27448_2 has been marked as BAD, because it uses the invalid shapes as inputs for BOP.

Test cases for the issue 0028690.

f542b7bbf1 0027252: Implicit-implicit intersection (Cylinder-Plane) loses intersection curve
1. Earlier we could not put any IntPatch_Point to the intersection curve. The fix makes the algorithm of IntPatch_Points searching more precise. It is achieved by redetermination of earlier found vertices with help of minimization the distance between boundary of one intersection argument and another intersection argument (surface).
2. Additional check has been added, if IntPatch_Point adjusted to the domain boundary is true intersection point.
3. Method Contap_ArcFunction::Surface() has been added.
4. Method LastComputedPoint() has been added for IntPatch_ArcFunction and Contap_ArcFunction classes.
5. Correction in FindMaxDistance() method (see IntTools_FaceFace.cxx file) according to pure Golden-ratio minimization algorithm. Earlier this function worked wrong with small searching intervals.

8109385697 0027362: Meshing performance
1) BRepMesh_FastDiscretFace.cxx:
- exclude planes from procedure of inserting internal points.
- localize declaration of the container aNewVertices in each method where it is needed.
- correct the logic of the method insertInternalVerticesOther, so that to separate the processes of removing extra points and addition of new points in different cycles, thus making the code more clear and in addition stable.
- insert useful output of intermediate mesh to a file in control() method for debug purposes (with definition DEBUG_MESH).

2) Add global functions MeshTest_DrawTriangles and MeshTest_DrawLinks to draw mesh data in debug session.

3) BRepMesh_FastDiscret:
- in the method Add calculations of deflections have been simplified for non-relative mode.
- replace the attribute MinDist with Deflection in EdgeAttributes structure. Correct its computation so that later to store this value as deflection of the polygon.

4) Make protection against exception in the method BRepMesh_Delaun::addTriangle() when an added triangle creates a third connection of a mesh edge.

5) BRepMesh_EdgeTessellator.cxx, BRepMesh_EdgeTessellationExtractor.cxx: use Geom2dAdaptor_Curve in order to use b-spline cache while computing value on a curve.

6) In BndLib_Box2dCurve::PerformBSpline, avoid creating new b-spline in case of requested parameter range differ from natural bounds insignificantly.

7) In GeomAdaptor classes, postpone building of cache till the time of its actual usage. So, creation of an adapter to compute intervals of continuity does not lead to creation of internal cache.

8) In the methods BRepAdaptor_Curve::Bezier and BSpline do not call Transformed() if transformation is identity.

9) In the classes Geom_BSplineCurve, Geom_BSplineSurface, Geom_BezierCurve, Geom_BezierSurface, Geom2d_BSplineCurve, Geom2d_BezierCurve change the method Pole() to return the point by const reference.

10) In CPnts_AbscissaPoint.cxx, compute derivative by D1 instead of DN to make use of b-spline cache.

11) Change test cases to actual state:
  - Number of triangles/nodes can grow due to more accurate work with deflection of edges. Now the edge is tessellated using its own tolerance instead of maximal tolerance of all shapes in the face.
  - Accept new numbers of mesh errors (free links, free nodes) for really bad shapes.
  - Correct the test "bugs/mesh/bug25612" to produce stable result.
  - Disable redundant checks in test cases bug25378* (lower limit for computation time).

- Speed up iso-lines computation for offset of bspline surfaces. For that use adaptor instead of original surface in evaluator of approximation.
- Add output of polylines for debug of insertInternalVerticesOther().

Reference data in test case bugs\moddata_2\bug453_3 have been changed to be close to expected theoretical values. This makes the test give stable result on different platforms.

e1c1b6b9f4 0027490: BRepMesh: Reduce number of memory allocations
1) Reduce the number of calls to malloc by grouping requests to larger blocks. To achieve this goal, the following ways are used:

- Containers of types sequence, list and map are initialized with an instance of NCollection_IncAllocator, at this taking care of the time of life of allocated objects, so that not to occupy huge amount of memory.

- Allocation of several arrays having the same and short life time is changed so that to allocate a buffer array of necessary size and to place arrays in this buffer.

2) In BRepMesh_FastDiscretFace, optimize the function filterParameters so that to avoid excess memory allocations.

3) In NCollection_CellFilter, change declaration of the method Reset to accept array by reference rather than by value.

4) Add Allocator() method in map, sequence and vector collection classes by analogy with list collection.

5) Correct the size of block for IncAllocator for x64 platform. In order free-ed block to be returned to the system its size should be at least 1024K on x64 and 512K on x86. This allows to retain free virtual space almost to the state before algorithm run.

6) Decrease amount of memory zeroed by calloc. For that, reduce theIncrement parameter of the embedded vectors of the classes NCollection_UBTreeFiller and BRepMesh_VertexInspector to default value 256.

7) Avoid computing bounding box when not necessary (if no relative deflection is used)

8) Cycles by wires of face using TopExp_Explorer are converted to use TopoDS_Iterator instead.

9) BRepMesh_FastDiscret::Add optimized to avoid storing sequences of faces and edges

10) The tests "mesh standard_* W7" are corrected to accept the new behavior. Earlier the following error took place:
Not connected mesh inside face 9
{12 13}
Now this error was replaced with another one:
free nodes (in pairs: face / node):
{9 12}
Actually it is not a regression, rather improvement, if we look at the snapshot.

11) Change other test cases to their actual state.

3510db6201 0026619: Tolerances of operands are modified using bop
0026796: The result of General Fuse operation is self-intersecting shape

The fix forces creation of new sub-shapes (vertex, edge) when the tolerance of some sub-shape of an argument is to be increased.

This new behavior is turned off by default. It can be turned on using two ways:
1) Setting 'locking' flag of the arguments.
2) Calling the method SetNonDestructive(Standard_True) of the API classes.

Various bug fixes in the algorithm:
- Compute correct tolerance values for intersections of type Line/Line, Line/Plane, Plane/Plane.
- In case of Line/Plane intersection check if line's vertices lie on the plane.
- Do not allow decreasing of the tolerance value of the Line/Line intersection vertex.
- In IntTools_EdgeEdge, call the method FindParameters with proper 3D tolerance of the curve.
- Force making copy of a degenerated edge if its vertex is touched but no 2D intersection with other curves is found.
- Remove pave blocks both ends of which became referring to the same vertex after vertices substitution.
- Avoid exception in IntTools_Context::IsVertexOnLine if Extrema is not done.
- Reduce tolerance of vertex/edge using actual distances to interfered shapes if it was increased due to line/line, line/plane, or plane/plane small intersection angle.
- Update tolerance of edges to reach all representations in a common block.
- In V-E intersections, check if a vertex hits beyond shrunk range, in such case create V-V interference.
- Do not put a section edge to the result if it becomes to be a micro edge after updating its vertex.
- Correctly make vertices same-domain during the work of MakeBlocks.
- Decrease shrunk range at least on a Precision::Confusion() in addition to vertex tolerance.
- Add Confusion to bounding boxes of new shapes in DS
- Add tolerance Precision::Confusion() to compare distances of touching cases to fix regressions.

Some explanation of new behavior of some test cases:

 1. Regressions:

a) blend simple X4
The problem is described in the issue #0026740. According to this description,  the result on the current MASTER seems to be wrong indeed.

b) boolean bcommon_complex C7 and boolean bcut_complex Q1
These test case use same shapes with different Boolean operation (COMMON and CUT). They are already BAD (on the MASTER). Now, some sub-shapes have become not-shared, simply. In my opinion, we shall apply new behavior of these tests.

c) boolean bsection M3
The problem described in the issue #0026777 exists even on the current MASTER.

d) boolean bsection M9
The problem is described in the message http://tracker.dev.opencascade.org/view.php?id=26815#c47546. Here, we have really regression in the picture.

e) boolean bsection N2

The problem is described in issue #0026814.

f) boolean volumemaker G1

The problem is described in issue #26020.

g) bugs modalg_1 bug1255 (and bug1255_1)

The problem is described in issue #26815.

h) bugs modalg_2 bug5805_18, bugs modalg_2 bug5805_42, bugs modalg_2 bug5805_46

The problem is described in issue #25925.

i) bugs modalg_3 bug602

The problem is describes in issue #602.

j) bugs modalg_5 bug24915

The problem is described in the message http://tracker.dev.opencascade.org/view.php?id=25929#c48565. It is not fixed by this issue.

k) bugs modalg_5 bug25838

2a739b6d66 0024357: BRepBuilderAPI_Sewing returns result with too high tolerance.
In method Approx_SameParameter::Build() for case when 2D and 3D curves is not same parameter calculation of maximal deviation is modified by following way :

Projection is considered as done only if parameter projected point falls within the current interval of parameters.

In the Approx_SameParameter considering tolerance after static method ProjectPointOnCurve was added.

In BRepAlgoAPI_Sewing catch of exception was added and computation of tolerance of edge if same parameter was changed in according to check in BRepCheck_Analyzer

In method Approx_SameParameter::Build() for case when 2D and 3D curves is not same parameter calculation of maximal deviation is modified by following way :

Modification in order to avoid warning

94f71cad33 0024682: Move out B-spline cache from curves and surfaces to dedicated classes BSplCLib_Cache and BSplSLib_Cache
1. B-spline cache was moved into separated classes: BSplCLib_Cache for 2D and 3D curves and BSplSLib_Cache for surfaces.

2. The cache is used now in corresponding adaptor classes (Geom2dAdaptor_Curve, GeomAdaptor_Curve and GeomAdaptor_Surface) when the curve or surface is a B-spline.

3. Algorithms were changed to use adaptors for B-spline calculations instead of curves or surfaces.

4. Precised calculation of derivatives of surface of revolution is implemented for the points of surface placed on the axis of revolution (Geom_SurfaceOfRevolution.cxx)

5. Small modifications are made to adjust algorithms to new behavior of B-spline calculation.

6. Test cases were modified according to the modern behavior.

7. Changes in BOPAlgo_WireSplitter, BOPTools_AlgoTools, BRepLib_CheckCurveOnSurface and ShapeAnalysis_Wire to use adaptors instead of geometric entities

8. Allow Geom2dAdaptor and GeomAdaptor in case of offset curve to use corresponding adaptor for basis curve

Modification of test-cases according to the new behavior.

af65fb1941 0025783: Visualization - allow Z-layer to draw 2D objects and to make it alternative to Overlay and Underlay
Add one more pre-defined Z-layer Graphic3d_ZLayerId_BotOSD.

Define new Transformation Persistence flags Graphic3d_TMF_2d and Graphic3d_TMF_2d_IsTopDown
for displaying objects in screen coordinates.
Anchor point defines angle of the screen to display the object in similar way as for Graphic3d_TMF_TriedronPers.

Extend Draw Harness command vdisplay with new options:
 -overlay as alias for -toposd.
 -underlay and -botosd.
 -noselect to prevent automatic selection activation.
 -dispMode and -highMode to define displaying and highlighting modes.
 -2d, -2dtopdown and -3d to manage displaying in screen coordinates.
 -trsfPers and -trsfPersPos for Transformation Persistence options.

Drop command vsettransmode, replaced by vdisplay.

f751596e46 0024623: Visualization - improve selection mechanism
Redesign of selection mechanism:
- implemented 3-level BVH tree for selection;
- selection now calculates in 3D space;
- intersection tests were moved to SelectMgr_BaseFrustum descendants;
- removed .cdl files in Select3D and .cdl related to selection in MeshVS;
- SelectMgr_ViewerSelectors are now shared between local and global contexts;
- transformations of sensitive entities are now stored in SelectMgr_SelectableObject only. Sensitive entities are independent from transformations, it is applied to SelectMgr_SelectingVolumeManager instance only;
- connected and multiple connected interactive objects are now represented by their child objects only for SelectMgr_SelectionManager;
- if interactive object has child objects, they will be stored as separate objects in SelectMgr_SelectionManager now.
- test cases bugs/vis/bug24623_1, bug24623_2, bug24623_3, bug24623_4 to test performance and memory issues.

15b54261a3 0022598: Approximation of p-curve by 2D line
Check whether p-curve being projected can be approximated by straight line is made before full-scale projection, to improve performance.
If straight, pcurve is created as Line only if this will lead to the same range parameterization as 3d curve, otherwise BSpline of degree 1 is created.
Re-approximation of line pcurves by bsplines removed from ShapeFix_Edge.
