Support of reading and writing tessellated geometry is added for the following STEP entities:
- triangulated face
- complex triangulated face
- tessellated shell
- tessellated solid
- tessellated shape representation
Models without BRep geometry (mesh formats like STL, OBJ and so on) are supported for writing to STEP.
New parameters are added to enable/disable tessellated geometry reading and writing:
- read.step.tessellated (On/Off/OnNoBRep) (On by default)
- write.step.tessellated (On/Off/OnNoBRep) (OnNoBRep by default)
OnNoBRep - tessellation is read/written only for entities for which there is no BRep representation.
Faces with poly triangulation are written in STEP as triangulated face entities with one coordinates list per face.
Only one poly triangulation per face (returned by BRep_Tool::Triangulation) is written to STEP.
Problem: the complete surface of the torus is not stored correctly in STEP format due to the fact that the edges are not properly ordered.
Change: added a mode for reordering edges in the wire with simultaneous use of 2d and 3d information (ShapeAnalysis_WireOrder). The new mode is used for torus-like surfaces before saving to STEP format.
Result: Torus correctly stored.
Incorrect curve handling.
If curve doesn't have trims and vertexes, we handle it such as trimmed curve, but it should be a simple curve.
Curves with only one vertex and one trim should handle by another way, such as a curve that has trims but doesn't have vertexes.
So I added conditions which handles these cases
Modified the method TopoDSToStep_MakeStepFace::Init
Added processing of degenerate toroidal surfaces, which are the base surfaces of offset surfaces
Added test
Possibility for adding LengthUnit info to XCAF document using special class XCAFDoc_LenghtUnit and XCAFDoc_LenghtUnitTool is implemented.
Package UnitsMethods is split: geom methods were placed to new file GeomConvert_Units which is in the toolkit TKXSBase, internal step scale factors was placed to StepData.
Updated UnitMethods to convert scale factor to different unit types.
Now, XSAlgo::XSAlgo_AlgoContainer is used to update unit info from static interface values.
New Draw command "XSetLengthUnit" and "XGetLengthUnit" for set or get XDE attribute.
Upgraded tests for STEP, IGES, OBJ, glTF, VRML formats to check area regressing with used unit.
Upgraded tests\de test cases to use any units in the "loop back" algorithms.
Progress indication mechanism is refactored to support incrementing progress within multithreaded algorithms.
The class Message_ProgressIndicator is only an interface to the user application.
It accumulates the progress provided by progress scopes.
The counter is protected by mutex for thread-safety.
The new class Message_ProgressScope replacing Message_ProgressSentry should be used to advance the progress.
The scopes are nested to each other to reflect the nested nature of operations.
The new class Message_ProgressRange should be used to pass the progress to sub-scopes.
All OCCT algorithms involving progress indication have been updated to new API.
Improvements in Draw_ProgressIndicator:
- Separate console mode has been added in order to make possible to put the progress into std::cout instead
or in addition to the draw interpreter, instead of trigger option "-tclOutput".
- Treatment of Ctrl-Break signal has been added.
Now any operation can be aborted by Ctrl-C or Ctrl-Break keystroke.
Added new test case 'perf fclasses progr_par' for testing of parallel work of the progress.
For small edges fully covered by tolerances of vertices BSpline periodic curves are converted to not periodic BSpline curves by cutting segment before writing.
In the class TopoDSToStep_MakeStepEdge permute of edge vertices for closed curves was added for the case when the range obtained from the vertex projection contradicts the edge range in order to avoid computation of the invalid edge range after reading.
Second test script for bug 0031301
"endl" manipulator for Message_Messenger is renamed to "Message_EndLine".
The following entities from std namespace are now used
with std:: explicitly specified (from Standard_Stream.hxx):
std::istream,std::ostream,std::ofstream,std::ifstream,std::fstream,
std::filebuf,std::streambuf,std::streampos,std::ios,std::cout,std::cerr,
std::cin,std::endl,std::ends,std::flush,std::setw,std::setprecision,
std::hex,std::dec.
TopoDS_Shape::NbChildren() - new method has been introduced.
TopoDS_Shape.lxx, TopoDS_TShape.lxx - inline methods have been moved to hxx.
TopoDS_TShape_Flags has been redeclared as enumeration instead of preprocessor macros.
Cyclic dependency between headers TopoDS_Shape.hxx and TopoDS_TShape.hxx eliminated.
Places where TopoDS_Iterator is used only for calculation of number of sub-shapes are updated to use NbChildren() instead
Code has been updated to remove no-op casts and implicit casts to Standard_Boolean.
Places of inproper use of Standard_Boolean instead of Standard_Integer
have been corrected:
- Bnd_Box, Bnd_Box2d
Bit flags are now defined as private enum
- HLRAlgo_BiPoint, HLRAlgo_EdgesBlock, HLRBRep_EdgeData, HLRBRep_FaceData
Bit flags are now defined as enum
- HLRAlgo_EdgeStatus, HLRBRep_BiPnt2D, HLRBRep_BiPoint
Bit flags are now defined as bool fields
- HLRAlgo_PolyData
Bit flags are now defined as Standard_Integer
- OSD_DirectoryIterator, OSD_FileIterator
Boolean flag is now defined as Standard_Boolean
- ShapeAnalysis_Surface::SurfaceNewton()
now returns Standard_Integer (values 0, 1 or 3)
- ChFi2d_FilletAlgo
now uses TColStd_SequenceOfBoolean instead of TColStd_SequenceOfInteger
for storing boolean flags
Method IFSelect_Dispatch::PacketsCount() has been dropped from interface.
ShapeFix_Solid::Status() has been fixed to decode requested status
instead of returning integer value.
TopOpeBRepBuild_Builder1 now defines map storing Standard_Boolean values
instead of Standard_Integer.
Persistence for Standard_Boolean type has been corrected
to keep backward compatibility:
- BinMDataStd, BinTools, FSD_BinaryFile
Broken Draw Harness commands vdisplaymode and verasemode have been removed.
BRepMesh_FastDiscretFace::initDataStructure() - workaround old gcc limitations
BRepMesh_IncrementalMesh::clear() - avoid ambiguity
Debug code enabled with OCCT_DEBUG macro corrected for compiling with new handles.
QANCollection_Handle.cxx simplified so as to avoid need of using /bigobj option when building by Visual Studio; templates of project files, CMake projects, and test perf fclasses handle corrected accordingly.
Script genproj corrected to recognize VTK and to build DRAWEXE as executable (rather than DLL).
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
Missing headers added; includes of headers "Handle_...hxx" removed.
Misuses of macro Handle() and its use in typedefs corrected.
Alias classes Profile and Option are removed from IFSelect; ones defined in MoniTool are used directly.
Removed header files defining only Handle classes (except Image_PixMap_Handle.hxx)
Classes SelectMgr_BaseFrustum and now inherit Standard_Transient and can be manipulated by Handle (not NCollection_Handle)
Fixed reference-type local variable pointing to temporary object
Use of handle in conditional expressions and comparisons to NULL are replaced by call to method IsNull()
add check for edges with null 2D and 3D curves for STEP,
for IGES problem exists only with wires, where non-invalid edge is only one, and it is not the last in wire(fixed).
Test case for issue CR25843
Macros ending on "DEB" are replaced by OCCT_DEBUG across OCCT code; new macros described in documentation.
Macros starting with DEB are changed to start with "OCCT_DEBUG_".
Some code cleaned.
1. DRAW-commands for curve/surface continuity returning were changed.
2. Output of "distmini" DRAW-command is amended.
3. Function MinMax() was moved from Standard_Real to IntPatch_ImpImpIntersection_4.gxx.
4. Incorrect computing of nbcurveC1 in Geom2dConvert::C0BSplineToC1BSplineCurve(...) function was liquidated.
Test cases were changed.
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.
