1. New sharing algorithm has been implemented. If intermediate point of some edge is included in the tube with center taken in another edge and radius equaled to maximal vertex-tolerance of both edges then these two edges are considered to be shared. This know-how touches edges only, which have common blocks with interfered faces. If they do not have any common-blocks the algorithm will work as before.
2. Interface of BOPAlgo_PaveFiller::IsExistingPaveBlock(...) method has been changed.
Creation of test case for issues #27128 and #27179
Adjusting some test cases according to their new behavior, because they are IMPROVEMENTS really (TODOs have been deleted).
New flag is inserted in parameters of static methods LinearProperties(...), surfaceProperties(...), volumeProperties(...). This flag defines to skip or not to skip second and next appearance shared topology entities (edges, faces, shells) in properties calculation.
Corresponding Draw commands is modified to take in account new parameter.
Test case for issue CR27273
Add option -skip into checkprops command
1. Algorithm of coincidence check between Walking and Restriction line has been improved in IntPatch_ImpPrmIntersection.
2. Creation of test case for this issue.
Topological tolerances changed to geometric tolerances.
Protection from the usage of invalid result is added to restore good projection.
Test cases are updated.
Test case added.
Correction of test case for issue CR27133
OpenGl_ShaderManager::stdComputeLighting() - handle single directional light specifically
for compatibility with broken OpenGL ES drivers.
Added test cases using built-in GLSL shading programs.
When reducing the tolerance values of the vertices put on section curves take into
account all section curves, not only those for which the tolerance have been reduced
(method void BOPAlgo_PaveFiller::CorrectToleranceOfSE()).
The new protection has been added to avoid reducing of tolerance values of vertices
to the values less than the tolerance values of edges containing these vertices.
Adjusting of test case bugs/modalg_5/bug25232_9
- method SelectMgr_SelectableObject::HasSelection became virtual, unnecessary variable was removed;
- redefined HasSelection method for multiple connected interactives;
- AIS_InteractiveContext::AddOrRemoveSelected was corrected to use global selection owner;
- test case for issue #27285
The map to protect the result of Boolean operation from duplicating parts in containers has been removed (method void BOPAlgo_BOP::BuildShape()).
The results of Boolean operations on containers will be the following:
1. For the arguments of collection type (WIRE, SHELL, COMPSOLID) containing overlapping parts the overlapping parts
passed into result will be repeated for each container from the input shapes containing such parts.
2. The result of the operation Fuse for the arguments of collection type (WIRE, SHELL, COMPSOLID) will contain
the same number of containers as the arguments. The overlapping parts (EDGES/FACES/SOLIDS) will be shared among them.
For example, the result of Fuse operation between two wires will be two wires sharing coinciding edges if any.
3. The result of the operation Common for the arguments of collection type (WIRE, SHELL, COMPSOLID) will consist
of the containers containing the same overlapping parts. For example, the result of Common operation between two
fully/partially overlapping wires will be two wires containing the same edges.
Style correction.
Added test case bugs/modalg_1/bug13538
Modified boolean test cases according to new begavior
Possibility to customize layout of installation of OCCT is introduced by:
- variable INSTALL_DIR_LAYOUT - select one of the two predefined layouts: either Windows (classic OCCT layout) or Unix (Linux standard)
- variables INSTALL_DIR_* (BIN, LIB, INCLUDE, RESOURCE, DOC, TESTS, SCRIPT, SAMPLES, DATA) - specify locations of relevant components
- variable INSTALL_DIR_WITH_VERSION (bool) - specifies whether full version of OCCT should be used in paths in Unix layout
Files LICENSE_LGPL_21.txt and OCCT_LGPL_EXCEPTION.txt are always installed.
Environment is extended to support non-default layouts.
For that, environment variables "CSF_OCCT*Path" are defined, corresponding to CMake variables INSTALL_DIR_* described above.
Visual Studio environment, DRAW, tests, samples are amended to use these variables instead of (or as alternative to) CASROOT.
Settings of Products-specific vars are removed from environment scripts.
File genconf.bat was corrected to avoid error message for the case when path to TCL contains spaces.
Product name in rc files changed to "Open CASCADE Technology".
1. Protection against getting access to null-handle has been entered.
2. Function AreSamePoints() has been substituted by appropriate method IntSurf_PntOn2S::IsSame(...)
Test cases for issues #27262 and #27263 have been created.
1. Processing when IntPatch_WLine/IntPatch_RLine goes through the seam edge has been improved in DecomposeResult(...) function (see IntPatch_ImpPrmIntersection.cxx).
2. Incorrect initialization of last point of IntPatch_WLine/IntPatch_RLine has been eliminated. Earlier it was the reason of exception.
Creation of test case for this issue.
Adjusting some test cases according to their new behavior. Namely:
1) tests\bugs\modalg_4\bug825 (bug825_2)
Details are described in issue #25915. In short, new intersection algorithm works better than old (WLine without "jumping"). However, Boolean operation loses degenerated edges of the sphere. Consequently, we get the result with Not-closed face.
2) tests\bugs\modalg_6\bug26684_2
TolReached of intersection curve has become smaller. Consequently, intersection algorithm works better than earlier.
Calling IntPatch_WLineTool::ComputePurgedWLine() algorithm is forbidden if Walking-line is obtained from analytic line.
Creation of test case for this issue.
Added test case that works in one of two modes:
1) create synthetic document (in old version of OCCT) containing all possible attributes.
2) open the document and compare all attributes with expected values.
Fixed reading of TDataStd_NamedData, TDataXtd_PatternStd, and PColStd_HArray2OfReal.
Point and curve representations are created even from NULL geometry handles.
The code is simplified by abandoning usage of templates from StdObjMgt_ContentTypes class for persistent data elements.
Fixed SetAsciiString Draw command failed when the target label contained NamedData attribute.
Arguments of genproj tool are revised:
* -path option eliminated (current directory is always used);
* IDE should be always indicated by first argument (instead of -target=<ide> option);
* second argument can be used to specify non-default platform (wnt, mac, lin, ios, qnx);
* option -h, -help, --help can be used to get help
* option -static can be used to build static libs with XCode
README.txt and docs on building are updated.
codeblocks.bat is corrected to be able to detect 32-bit installation of Code::Blocks on 64-bit Windows.
Remains of support of OpenCL (obsolete) are commented out in genconf.tcl
genproj.tcl will not copy env.bat if it already exists.
A few remaining places mentioning .cdl files are corrected to mention only .hxx
Obsolete description of storage in old format is revised in OCAF User's Guide.
The code in Standard_Type::type_instance<T>::get() distinguishes between compilers supporting and not supporting N2660. VS2013 was incorrectly considered as supporting, although the comment stated the opposite.
The fix makes VS2013 treated as not supporting N2660.
Technical docs are reviewed to:
* update references to page with third-party products
* update description of persistence, handles, and RTTI according to changes in OCCT 7.0
* remove references to CDL, WOK, and WOK-generated stuff
* update the list of environment variables
Description of building OCCT with WOK and automake scripts is removed from documentation.
Use of genproj utility is described in pages on building with MSVC, Code::Blocks, and XCode projects.
New script genconf allows starting configuration GUI explicitly; dialog is slightly revised.
Script genproj.sh is renamed to genproj; permissions for scripts are corrected for Linux.
Script env.bat does not set anymore environment required for Products.
Possibility to read shapes and OCAF documents from old persistence format (Std and StdL schema) is restored.
Test cases used old persistent files on input are restored with suffix "_std"
Removing toolkit from OS package
View-projection matrix was added to raytrace shaders (as uniform) in order to compute correct depth values for OpenGL.
For path tracing the additional depth buffer sampler was added to Display.fs program. It allows propagation of depth values from internal FBO to resulting FBO.
The old approach of mixing of OpenGL and ray-tracing graphics was kept in order to keep correct blending of transparent ray-traced objects with non-transparent OpenGL objects.
Some pre-release updates, reviewing and implementation of some adequate remarks from JMA:
- redundant chapters in IGES and STEP guides
- proofreading of recent insertions in Draw, and tests guides
- mathjax information
- data, version, addresses, system requirements in overview.md
Corrections
AIS_ColorScale, AIS_Dimension - the protected method DrawText()
has been renamed to drawText() to avoid name collisions with macros.
_MSC_VER/_WIN32 misuse has been fixed in several places.
Header <malloc.h> is now included where alloca() is used.
Draw_Window - dllimport flag has been dropped from inline methods.
TKernel - mandatory dependencies Winspool.lib and Psapi.lib
are now linked explicitly (instead of msvc-specific pragma syntax).
CMake scripts - the option -std=c++0x has been replaced by -std=gnu++0x
for mingw to allow extensions (like _wfopen() and others).
The minimum Windows version has been set to _WIN32_WINNT=0x0501.
Invalid options "-z defs" and "-lm" have been dropped for mingw.
Flag --export-all-symbols has been added to CMAKE_SHARED_LINKER_FLAGS
to workaround missing vtable symbols when using mingw.
FreeType is now linked explicitly on Windows.
Draw::Load() - "lib" suffix is now prepended on mingw as well.
Drop redundant declaration of _TINT from OSD_WNT_1.hxx.
NCollection_UtfString::FromLocale() - platform-specific code has been moved to .cxx file.
Draw_BasicCommands - fixed incorrect mingw64 version macros.
genproj, cbp - added workaround for process argument list limits on Windows.
TKSTEP linkage is failing on this platform due to too long list of files.
The list of object files to link is now stored in dedicated file which is passed to gcc.
Option "-z defs" removed from CMake linker options to avoid problems when building with different configurations of VTK on Linux
Some MinGW-specific compiler warnings (potentially uninitialized vars, use of NULL, parentheses in conditional expressions) are fixed (speculatively)
MeshVS_Mesh selection logic in MeshVS_SMF_Mesh mode (entire mesh) has been optimized.
MeshVS_Mesh::ComputeSelection() now creates single sensitive entity
MeshVS_CommonSensitiveEntity (new class) instead of small sensitive entity on each element.
MeshVS_SensitiveQuad (new class) and Select3D_SensitiveTriangle are used instead of Select3D_SensitiveFace for local selection to reduce memory consumption when possible.
New method HLRBRep_HLRToShape::CompoundOfEdges with options:
- type of resulting edge
- visibility
- 3d/2d
has been added.
Minor correction of comments
Graphic3d_TypeOfData - added Graphic3d_TOD_FLOAT for passing single-float vertex attributes.
Graphic3d_TOA_CUSTOM - changed value to increase the range for custom vertex attributes locations (to fit into hardware limits).
Graphic3d_ShaderProgram::SetVertexAttributes() - introduced API for defining custom vertex attributes.
For compatibility with automated wrappers:
- Graphic3d_Buffer::Init() - added prototype taking NCollection_Array1<Graphic3d_Attribute> instead of C array
- Graphic3d_IndexBuffer::InitInt32() - added typed initialization method.
- Graphic3d_ShaderProgram::PushVariableVec3() and others - added typed methods to push uniform varibales.
Method StlAPI_Writer::Write() is reimplemented to write triangulation directly, without conversion to StlMesh_Mesh.
New DRAW command "tessellate" is added to generate rapidly triangulation of prescribed size (on surface).
Command "tricheck" is protected to deal correctly with triangulation without UV data.
New tests added: perf de bug26338_1 and _2; bugs stlvrml bug26338
Correction of testing environment
Added ldl dependency for TKernel only (other toolkits were checked, no undefined symbols)
Added option "-z defs" for linking on Linux
Added lm dependency for all toolkits
