Fixing problem with bugs modalg_3 bug606_2
Aspect_IS_HOLLOW now an alias to Aspect_IS_EMPTY and Aspect_IS_HIDDENLINE does not implicitly enables mesh edges,
so that Graphic3d_AspectFillArea3d::SetDrawEdges() should be set independently.
OpenGl_ShaderManager now provides built-in GLSL programs for drawing mesh edges
in single pass (and on OpenGL ES which does not provide glPolygonMode()).
Graphic3d_RenderingParams::ToEnableAlphaToCoverage is now enabled by default

which can be managed by OpenGl_Caps::usePolygonMode flag (desktop OpenGL only).
glPolygonMode() is also used as fallback regardless OpenGl_Caps::usePolygonMode flag
when GLSL programs are not supported (Geometry Shaders are required)

* crepeatshape - repeats the periodic connected shape in requested directions requested number of times;
* cperiodictwins - returns all periodic twins for the shape;
* cclearrepetitions - clears all previous repetitions of the periodic shape, keeping the shape periodic.
Documentation & test cases for the new algorithm.
Implementation of the new class *BOPAlgo_MakePeriodic* for making the shape periodic in 3D space.
Periodicity of the shape means that the shape can be repeated in any periodic direction any number of times without creation of the new geometry or splits.
The idea of this algorithm is to make the shape look similarly on the opposite sides or on the period bounds of periodic directions.
It does not mean that the opposite sides of the shape will be mirrored. It just means the the opposite sides of the shape should be split by each other and obtain the same geometry on opposite sides.
Such approach will allow repeating the shape, i.e. translating the copy of a shape on the period, without creation of new geometry because there will be no coinciding parts of different dimension.
Draw commands for the new algorithm:
* makeperiodic - makes the shape periodic in required directions;
* repeatshape - repeats the periodic shape in requested periodic direction;
* periodictwins - returns the periodic twins for the shape;
* clearrepetitions - clears all previous repetitions of the periodic shape.
Documentation & test cases for the algorithm.
1. Check whether the mesh satisfies the required angular deflection has been amended. Namely normals (to the surface) in the ends of any not "frontier" link are made collinear (with the given angular tolerance).
2. New parameters AngleInterior and DeflectionInterior have been added in IMeshTools_Parameters structure.
3. In case of thin long faces with internal edges, add points of internal edges to control parameters using grabParamsOfInternalEdges() in order to avoid aberrations on its ends. Disable addition of parameters from boundary edges in case of BSpline surface. Deviation can be controlled through the deflection parameter.
4. Grab parameters from edges in case if there is just a single interval on BSpline surface along U and V direction.
Removed tight connections between data structures, auxiliary tools and algorithms in order to create extensible solution, easy for maintenance and improvements;
Code is separated on several functional units responsible for specific operation for the sake of simplification of debugging and readability;
Introduced new data structures enabling possibility to manipulate discrete model of particular entity (edge, wire, face) in order to perform computations locally instead of processing an entire model.
The workflow of updated component can be divided on six parts:
* Creation of model data structure: source TopoDS_Shape passed to algorithm is analyzed and exploded on faces and edges. For each topological entity corresponding reflection is created in data model. Note that underlying algorithms use data model as input and access it via common interface which allows user to create custom data model with necessary dependencies between particular entities;
* Discretize edges 3D & 2D curves: 3D curve as well as associated set of 2D curves of each model edge is discretized in order to create coherent skeleton used as a base in faces meshing process. In case if some edge of source shape already contains polygonal data which suites specified parameters, it is extracted from shape and stored to the model as is. Each edge is processed separately, adjacency is not taken into account;
* Heal discrete model: source TopoDS_Shape can contain problems, such as open-wire or self-intersections, introduced during design, exchange or modification of model. In addition, some problems like self-intersections can be introduced by roughly discretized edges. This stage is responsible for analysis of discrete model in order to detect and repair faced problems or refuse model’s part for further processing in case if problem cannot be solved;
* Preprocess discrete model: defines actions specific for implemented approach to be performed before meshing of faces. By default, iterates over model faces and checks consistency of existing triangulations. Cleans topological faces and its adjacent edges from polygonal data in case of inconsistency or marks face of discrete model as not required for computation;
* Discretize faces: represents core part performing mesh generation for particular face based on 2D discrete data related to processing face. Caches polygonal data associated with face’s edges in data model for further processing and stores generated mesh to TopoDS_Face;
* Postprocess discrete model: defines actions specific for implemented approach to be performed after meshing of faces. By default, stores polygonal data obtained on previous stage to TopoDS_Edge objects of source model.
Component is now spread over IMeshData, IMeshTools, BRepMeshData and BRepMesh units.
<!break>
1. Extend "tricheck" DRAW-command in order to find degenerated triangles.
2. Class BRepMesh_FastDiscret::Parameters has been declared as deprecated.
3. NURBS range splitter: do not split intervals without necessity. Intervals are split only in case if it is impossible to compute normals directly on intervals.
4. Default value of IMeshTools_Parameters::MinSize has been changed. New value is equal to 0.1*Deflection.
5. Correction of test scripts:
1) perf mesh bug27119: requested deflection is increased from 1e-6 to 1e-5 to keep reasonable performance (but still reproducing original issue)
2) bugs mesh bug26692_1, 2: make snapshot of triangulation instead of wireframe (irrelevant)
Correction in upgrade guide.
Provide possibility to perform Boolean operations on open solids.
Implementation of the new method *BOPAlgo_Builder::BuildBOP* performing the construction of the result shape for the given type of Boolean operation.
This approach does not rely on the splits of solid to be correct and looks for the faces with necessary state relatively opposite solids to build the result solid.
The call to this method is performed from BOP algorithm in case there were open solids in the arguments.
Implementation of the draw command *buildbop* performing a call to the method above.
New algorithms calculating global properties on mesh data have been added:
- BRepGProp_MeshCinert computes the global properties of polylines represented by a set of points;
- BRepGProp_MeshProps computes the global properties of a surface mesh.
Existing tool BRepGProp now automatically uses new algorithm for triangulation-only faces.
By default, algorithm will use exact geometry objects (surfaces), when it is available (as before the patch);
this behavior can be switched by a new flag UseTriangulation, forcing usage of triangulation instead of exact geometry when both defined.
Implementation of the method for simplification of the result of Boolean Operation on the API level.
The method BRepAlgoAPI_BuilderAlgo::SimplifyResult has been added, so the derived classes such as BooleanOpeation and Splitter can also use this method.
The result shape simplification should be called after the operation is done. The simplification is performed by the means of ShapeUpgrade_UnifySameDomain algorithm.
Draw command "bsimplify" has been added to control the simplification options.
Documentation for new functionality and draw commands controlling the options of Boolean operations.
Test cases for the new functionality.
Side-effect change:
The algorithms in Boolean component have been changed to use the BRepTools_History as a History tool.
Now it became possible to disable the collection of shapes modifications during Boolean Operations, which may be useful for performance sake (in draw the option is controlled by *setfillhistory* command).
Draw command "unifysamedom" has been changed to accept the angular tolerance in degrees instead of radians.
The reason of this issue is in incorrectly interpreted the generic class "TheExtPC" (eliminated after the fix 0024773) as Extrema_ExtPC2d. Correct interpretation must be "Extrema_EPCOfExtPC2d" class.
Now this problem has been fixed in the class Geom2dGcc_Circ2dTanCenGeo.
New testgrid "lowalgos 2dgcc" has been created.
- XCAFNoteObjects_NoteObject transfer object for note's auxiliary data was added. It contains the following fields:
text and attachment positions, note plane and tesselated presentation
- GetObject/SetObject methods were added to XCAFDoc_Note attribute. The following sub-labels were added to handle transfer object:
1 - text position
2 - note plane
3 - attachment point
4 - tesselated presentation
- documentation updated
Off-topic: procedure genproj now gives meaningful error message if new package is added but not listed in UDLIST
Implementation of the mechanism for unification of the history commands for all OCCT algorithms.
The following Draw commands should be used to track the history of shapes modifications of any operation:
- modified - to find the shapes modified from the given shape in the given history.
- generated - to find the shapes generated from the given shape in the given history.
- isdeleted - to check if the given shape has been deleted during operation.
The mechanism allows fast & easy enabling of the DRAW history support for the algorithms supporting the history on the API level (i.e. the algorithm should have the methods Modified(), Generated() and IsDeleted()).
To enable the draw history support it is necessary to store the history of the algorithm into the session. For instance:
TopTools_ListOfShape Objects = ...; // Objects
TopTools_ListOfShape Tools = ...; // Tools
BRepAlgoAPI_Cut aCut(Objects, Tools); // Boolean cut operation
BRepTest_Objects::SetHistory(Objects, aCut); // Store the history for the Objects (overwrites the history in the session)
BRepTest_Objects::AddHistory(Tools, aCut); // Add the history for the Tools
To get the stored history in draw the command "savehistory" should be used. It saves the history kept in session into a Drawable object with the given name:
# perform cut
bcut r s1 s2
# save history of cut
savehistory cut_history
explode s1 f
modified m cut_history s1_1
The Draw History commands of the following algorithms have been removed:
- Boolean Operations;
- Defeaturing;
- Unify same domain;
- Sweep;
- Thrusections;
All these algorithms have been switched to support the new Draw history mechanism.
The Fillet and Blend algorithms have been also enabled to support history commands.
Implementation of the 3D model De-featuring algorithm intended for the removal of the unwanted parts (or features) from the model consisting of solids. The features can be the holes, protrusions, gaps, chamfers, fillets etc.
The algorithm removes all possible requested features from the shape and builds the new shape as a result. The input model is not modified.
On the API level the algorithm is implemented in the class *BRepAlgoAPI_Defeaturing*. The actual features removal is performed by the low-level algorithm *BOPAlgo_RemoveFeatures*.
Documentation of the new classes.
Implementation of the DRAW commands for working with new algorithm.
Test cases for the new functionality.
Changes in other algorithms used by De-featuring algorithm:
- Provide history support for the solids in *ShapeUpgrade_UnifySameDomain* algorithm;
- Implementation of the mechanism to merge History of any Algorithm with standard history methods such as IsDeleted(), Modified() and Generated() into *BRepTools_History*.
In the algorithm math_FunctionRoots, improve the case when it is needed to find the extremum of the function. Earlier, to solve this task the method of gold section was used. With the patch, firstly the algorithm tries to find zero value of the derivative function. In most cases it gives precise result. Secondly, the algorithm tries to find zero value of the function using the old approach. The algorithm chooses the best solution among two computed by different methods.
In the method PutStickPavesOnCurve of BOPAlgo_PaveFiller, forbid putting a vertex to the end of the curve if this end already has a vertex assigned to it. This allows getting rid of unwanted colliding of vertices.
In the method UpdatePaveBlocks of BOPAlgo_PaveFiller, make the check for micro edges more precise.
New category of tests "lowalgos" has been added. Tests for low level algorithms are to be put there. "2dinter" is a new group of tests in this category.
Introduction of the new key for "2dintersect" command, allowing printing the intersection state for each point.
It has the following syntax now:
"2dintersect curve1 [curve2] [-tol tol] [-state]"
Options:
-tol - allows changing the intersection tolerance (default value is 1.e-3);
-state - allows printing the intersection state for each point.
Correct the test case bugs/modalg_7/bug28274 to make proper checks of the result.
1. Implementation of the *Generated* method for the algorithms in Boolean Component.
In terms of these algorithms the shape from the arguments can have Generated shapes only if these new shapes have been obtained as a result of pure intersection (not overlapping) of this shape with any other shapes from arguments.
Thus, the Generated shapes are always:
* VERTICES created from the intersection points and may be Generated from edges and faces only;
* EDGES created from the intersection edges and may be Generated from faces only.
So, only EDGES and FACES could have information about Generated shapes. For all other types of shapes the list of Generated shapes will be empty.
2. Optimization and simplification of the Modified and IsDeleted methods based on the correct filling of the BOPAlgo_BuilderShape::myImagesResult map.
3. Provide history of unification of the solids in the CellsBuilder algorithm.
4. Update of the documentation of Boolean Operations User guide with new chapter "History Information" describing rules for filling history for operations in Boolean Component.
5. Test cases for the issue. New grid "history" has been added into "boolean" category.
1. Implementation of the user-defined option for usage of Oriented Bounding Boxes (OBB) in Boolean Operations for additional filtering (rejection) of selected for intersection pairs of sub-shapes.
By default the usage of OBB is turned off.
To enable/disable its usage the method SetUseOBB(flag) should be used. This method is available for all operations in Boolean Component.
To enable/disable it in draw the command "buseobb 0/1" should be used. Note, that this will affect all subsequent operations.
The OBB for the shapes are built by first necessity and stored into operation context (IntTools_Context).
2. Usage of the OBB in some test cases.
1. The class Bnd_OBB has been created to describe the Oriented Bounding Box.
2. Several key methods have been implemented: Bnd_OBB::IsOut(...), Bnd_OBB::Add(...) and Bnd_OBB::Enlarge(...).
3. Interface of Bnd_Box class has changed. New methods have been created. See Bnd_Box.hxx for detailed information.
4. BRepBndLib and Draw_Box classes have been amended in order to provide correct work with Bnd_OBB class.
5. Interface of "bounding" DRAW-command has been changed. Please see help for detailed information.
6. New DRAW-command "isbbinterf" has been created. Please see help for detailed information.
7. "boundingstr" and "optbounding" DRAW-commands have been eliminated because their function can be made by "bounding" DRAW-command (e.g. see tests/bugs/vis/buc60857 or samples/tcl/snowflake.tcl test cases).
8. Documentation has been updated.

for individual testing.
Expressions for derivatives are corrected.
New Draw command "intconcon" for intersection 2d conic curves is created.
Test command OCC29289 (file QABugs_20.cxx) is created for individual testing math_TrigonometricEquationFunction.
It is used in tests/bugs/modalg_7/bug29289
In order to improve performance of Boolean Operations on the relatively fast cases the following improvements have been made:
1. Initialization of the FaceInfo information for the faces participating in Face/Face interference, even when the gluing is ON, to take into account intersection of their sub-shapes.
2. Code simplification & duplication removal - the methods BOPAlgo_ShellSplitter::MakeConnexityBlocks and BOPAlgo_WireSplitter::MakeConnexityBlocks have been unified into BOPTools_AlgoTools::MakeConnexityBlocks.
3. Avoid unnecessary bounding box computation for solids during DS initialization. The bounding boxes for solids will be computed during the building stage to find faces located inside solids.
For the shape self-interference check (performed by the BOPAlgo_CheckerSI), the bounding box is still computed, as it is necessary to resolve Shape/Solid intersections.
4. Use only three sample points to check coincidence of line and plane.
5. Perform necessity of planes intersection only when the gluing is off.
6. Avoid repeated initialization of 2D classifier while building splits of the faces.
7. Post treat stage:
7.1. Method CorrectWires: Save edge's data (PCurve, parameter of the vertex, range) to avoid its recalculation.
7.2. Method CheckEdge: While checking vertices on edges avoid unnecessary calculation of their location.
8. Provide possibility to disable the classification of the input solids on the inverted status (to be the holes in the space).
9. Avoid building of bounding boxes for faces/solids during splitting of the input arguments for their classification relatively hole faces/shells if there are no holes created.
10. Avoid rebuilding of the faces/solids from arguments which does not acquire any inside parts from other arguments during the operation by using their draft versions as their splits.
Test cases for the issue.
Correction of the test cases boolean gdml_public A9 and bugs modalg_7 bug28485 as they are improvements.
Additional test case for the issue #28485 as it is fixed by the current changes.
NCollection_UtfString and NCollection_UtfIterator classes are refactored to use methods overloading instead of switches to dispatch implementation depending on character (Unicode code unit) size.
ICC-specific preprocessor directives are added to avoid warnings.
Unused local functions and variables, class methods, unreachable statements, and extra throw() declarations reported by ICC are removed.
Usage of "expl" for name of local variable is avoided as it conflicts with standard C function "expl" defined in math.h as preprocessor macro.
Non-standard (MS-specific) argument envp is removed in definition of main() function on Windows.
Functions _main_ and _WinMain_ are renamed to Draw_Main and Draw_WinMain, respectively, to avoid using names reserved in C++.
Doxygen warning is fixed in XDE User's Guide.
Documentation is added in a new "Inspector" page of "User Guides".
Inspector plugins has some improvements by the documentation needs.
New DRAW scripts are implemented for 'tinspector' command.
1. A tool to annotate items in the hierarchical product structure was added. The tool is located under
fixed label 0:1:9. It operates two basic entities: notes and annotations located under 0:1:9:1 and 0:1:9:2
hives correspondingly. A note is an attribute derived from base class XCAFDoc_Note that is attached to a separate
label under the notes hive. An annotated item is represented by XCAFDoc_AssemblyItemRef attribute
attached to a separate label under the annotated items hive. Notes are linked to annotated items by means of
XCAFDoc_GraphNode attribute, where notes play parent roles and annotated items - child roles.
2. XCAFDoc_AssemblyItemRef defines a weak reference to a label with optional attribute GUID or sub-shape index.
3. A capability to store note/annotation labels in XCAFDoc_ViewTool was added.
4. XDE User guide was updated
STL Reader and Writer tools have been refactored to improve performance and usability:
- Basic reading of STL file is separated to abstract class RWStl_Reader which is not bound to particular data structures; the target data model can be bound via inheritance.
- RWStl package uses class Poly_Triangulation to represent triangular mesh.
- Obsolete data structures and tools (packages StlMesh and StlTransfer) are removed.
AIS_LengthDimension interface was extended to allow setting a custom dimension direction.
The value of dimension in this case is equal to projection of the distance between dimension attributes(points) to this direction.
vlengthparam command is implemented to set custom length direction in DRAW.
Template for LaTeX header used in generation of PDF manuals is corrected to avoid multiple errors during processing by LaTeX (which can eventually lead to LaTeX aborting if their count exceeds 100).
Names of log files generated by gendoc command are made dependent on target format and (for PDF output) document name.
Formatting bug is fixed in DRAW User Guide
0. Basic tools for defining classes representing alerts (errors, warnings etc.) and collecting them during execution of algorithms are added in Message package.
1. Refactoring of the Error/Warning reporting system of the algorithms in Boolean Component.
To dump the description of the Error/Warning status of the algorithm the DumpErrors/DumpWarnings method should be called.
Also, the methods GerErrorMsg(int Error) and GetWarningMsg(int Warning) have been implemented to get the description for the given Error/Warning.
All Error/Warning statuses are now listed in the enumeration ErrorStatusEnum/WarningStatusEnum of the algorithm.
It is also possible to get the shapes for which the warning has been set by using the method GetWarningShapes().
2. The new class BOPAlgo_Options has been created to unify the options of the BOPAlgo_* and BRepAlgoAPI* algorithms.
3. The new checks across the algorithms have been added to detect and report errors and warnings.
4. Test cases
boolean bopcut_complex B9 E1 E5 E8
boolean bopfuse_complex B4 B5 C9 D1 D4 D5 D6 D7
have been rewritten to use Cells Builder algorithm instead of Boolean Operations algorithm, because latter always returns error "Unsupported Boolean operation" for these cases.
5. New chapter has been added in the user guide for Boolean Operations - Error / Warning reporting system.
6. Added comment to NCollection_List::Remove(Iterator&)
