* Details on
https://github.com/Open-Cascade-SAS/OCCT/releases/tag/V7_8_1
- update to version 7.8.0
* General
+ Fixed TDataStd_NamedData HasSmth() methods to no longer
return true for empty containers.
+ Improved general performance through code updates with static
analysis.
+ Implemented "Memory Manager" configurations: Native, TBB,
JeMalloc, Flexible. JeMalloc leads to a performance increase
of up to 40% for large files.
+ Introduced CMake configuration for optimization profiles:
Default and Production. Production activates all available
compiler optimizations.
+ Implemented move semantics into NCollection and TCollection
containers.
+ Modernized NCollection_Vector(NCollection_DynamicArray),
NCollection_Array1, and NCollection_Array2.
+ Updated memory allocation functionality to avoid unnecessary
memory cleaning (set 0).
+ Modernized NCollection_IncAllocator (optimized pool for
small objects).
* Modeling
+ Addressed multiple bug fixes and improvements for various
modeling algorithm methods.
+ Increased memory management performance.
+ Improved overall modeling stability.
+ Resolved canonical geoplane detection problems.
* Visualization
+ Resolved compilation issues related to vtk 9.2.6.
+ Improved SelectMgr_EntityOwner to process the selection
scheme.
+ Modified Image_AlienPixMap::Save() to write into a memory
buffer instead of a file.
+ Reduced sensitivity of lines.
+ Extended AIS_AnimationObject with syntax for defining
rotation around a specific point.
+ Introduced separate gesture mappings for dragging to
AIS_ViewController.
+ Integrated the ability to scale by moving the mouse on
the OY axis.
* Mesh
+ Fixed BRepMesh_IncrementalMesh issue with overflowing
system memory.
+ Unhandled Standard_OutOfRange, BRepMesh_PairOfIndex::Append()
no longer prevents triangulation with large deflection
values.
* Data Exchange
+ Resolved multiple issues regarding DE Wrapper and Step import
and export.
+ Increased STEP parser performance.
+ Introduced thread-safety interface to STEP import and export.
+ Reorganized DE ToolKits according to specific CAD formats.
+ Introduced DE plug-in system to load CAD format providers
during library loading time.
+ Fixed stability issues with XBF and IGES file formats.
+ Addressed general problems with importing VRML V1.
+ Improved processing of STEP-oriented dimensions.
* Draw Test Harness
+ Enabled loading of plugins on Linux OS.
+ Reorganized DRAW DE ToolKits according to specific CAD
formats.
+ Resolved environment-related issues with debug tools
DrawTrSurf_Set, DrawTrSurf_SetPnt, and `DrawTrSurf_SetPnt2d.
