Common material definition now occupies 4x2 vec4 instead of 5x2 vec4.
Getters of Common material properties within Declarations.glsl
have been renamed to match PBR material syntax (e.g. take IsFront flag as function argument).
Auxliary macros (like occTextureColor()) has been renamed (like occMaterialBaseColor())
and adjusted to return material property directly instead of taking it as argument.
OpenGl_Context now activates Ray-Tracing and arbTboRGB32 for GLES 3.2.
Removed initialization of some uniforms from GLSL code.
Fixed implicit casts within Ray-Tracing shaders.
Information about normals are stored in BinOCAF, XmlOCAF, BRep and BBRep (in case of triangulation-only Faces).
Versions of formats have been changed (11 for TDocStd, 4 for BRep Shape and 3 for Binary BRep Shape)
theWithNormals parameter added to BRepTools::Write()
IsWithNormals()/SetWithNormals() function added to BRepTools_ShapeSet
-normals/-noNormals option added to StoreTriangulation DRAW command
-normals/-noNormals option added to writebrep DRAW command
Tests for writing to brep/binary brep/BinXCaf/XmlXCaf added
Test for StoreTriangulation options -normals/-noNormals added
Two virtual methods NewDocument() and InitDocument() are moved from TDocStd_Application to its parent class CDF_Application. In TDocStd_Application these methods remain redefined. These little changes allow creation of a new document only in one virtual method NewDocument(). The methods CreateDocument() in all retrieval drivers are deleted.
Modified files:
- CDF_Application.hxx and cxx: two virtual methods NewDocument() and InitDocument() are moved from TDocStd_Application. The input parameter TDocStd_Document is changed to parent class CDM_Document.
- TDocStd_Application.hxx and cxx: redefines new virtual methods NewDocument() and InitDocument() of the parent class CDF_Application.
- BinLDrivers_DocumentRetrievalDriver.hxx and cxx, StdLDrivers_DocumentRetrievalDriver.hxx and cxx, XmlLDrivers_DocumentRetrievalDriver.hxx and cxx, PCDM_Reader.hxx: a virtual method CreateDocument() is deleted.
- TObj_Application.cxx, XCAFApp_Application.hxx and cxx: down-casting to a descendant class TDocStd_Document is applied.
Documentation:
- upgrade.md is modified.
Adaptor2d_Curve2d, Adaptor3d_Curve and Adaptor3d_Surface now inherit Standard_Transient.
Interfaces Adaptor2d_HCurve2d, Adaptor3d_HCurve, Adaptor3d_HSurface and their subclasses
are now aliases to Adaptor2d_Curve2d, Adaptor3d_Curve and Adaptor3d_Surface.
Removed numerous unsafe reinterpret casts.
Generic classes Adaptor3d_GenHCurve, Adaptor3d_GenHSurface, Adaptor2d_GenHCurve2d have been removed.
Several redundant .lxx files have been merged into .hxx.
Removed obsolete adaptor classes with H suffix.
AIS_SelectionScheme enumeration is defined to set which selection behaviour is used in Select of context
AIS_InteractiveContext is corrected to use single Select method instead of combination of Select/ShiftSelect methods with a selection scheme parameter.
Upgrade: Select() -> SelectDetected/Rectangle/Polygon(AIS_SelectionScheme_Replace), ShiftSelect -> SelectDetected/Rectangle/Polygon(AIS_SelectionScheme_XOR)
1. Unification of usage of a storage version of an OCAF document by XML and binary file formats.
2. A new format version enumeration in TDocStd package: TDocStd_FormatVersion.
3. Removal of unnecessary methods for storage version like XmlLDrivers::StorageVersion() and BinLDrivers::StorageVersion().
4. Support of old documents (storage version <= 9) in binary file format (came from ESA).
New files:
- TDocStd_FormatVersion.hxx: a new storage format version enumeration for an OCAF document.
Modified files:
- CDM_Document.hxx and cxx: removal of storage format version property (moved to TDocStd_Document).
- TDocStd_Document.hxx and cxx: a storage format version property (moved from CDM_Document).
- BinLDrivers_DocumentSection.hxx and cxx: support of old document storage version in binary file format.
- BinDrivers_DocumentStorageDriver.hxx and cxx,
- BinLDrivers_DocumentStorageDriver.hxx and cxx,
- BinLDrivers_DocumentRetrievalDriver.cxx,
- XmlLDrivers_DocumentRetrievalDriver.cxx,
- XmlLDrivers_DocumentStorageDriver.cxx: usage of document storage version from TDocStd_Document in storage and retrieval drivers.
- DDocStd_ApplicationCommands.cxx: draw-command name StorageVersion is replaced by StorageFormatVersion (to be the same everywhere). A corresponding script is corrected too.
New test:
- bugs caf bug29217: a test case for old document storage version in binary file format. It checks several attributes saved by the version TDocStd_FormatVersion_VERSION_7 (old) and the latest version.
Modified test:
- caf presentation M1: the test used a file in the current folder, not in {imagedir} like all other tests.
- bugs caf bug28691
Documentation:
- dox/upgrade/upgrade.md
// All remarks are fixed.
Construction of TCollection_ExtendedString from plain C string is fixed to consider input string as UTF-8 in several places (identified as described in notes to #31113).
Message_MsgFile is corrected to load resource file as UTF-8 (unless it has BOM indicating use of UTF-16).
Added tests for use of Unicode in some DRAW commands (bugs demo bug14673_*)
Enumeration values have been renamed to use complete prefix Graphic3d_NOM_ -> Graphic3d_NameOfMaterial_
and to match string names (with old values preserved as aliases).
Documentation of global variables available for the test script during test execution is improved.
Off-topic: mark-up error is fixed in DRAW user guide

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.
Fixed a couple of misprints, usage of changed classes / methods.
Added references to other supported 3d displays.
Added reference to PBR metallic-roughness material properties in addition to Common.
