- AIS_InteractiveContext - create new dummy class field to have an empty TopoDS_Shape object.
- AIS_Point, PrsMgr_PresentableObject - rename static variables to local function variables.
- AIS_Shape, SelectMgr_SelectableObject - remove unused static variables.
- Graphic3d_MaterialAspect, V3d_Viewer - make global static variables as constant.
- V3d_View - move global variable zRotation to class field.
- Move a variable theCurrentSelection as a field of AIS_InteractiveContext and AIS_LocalContext classes. Multiple selection is not used now, so each Context have an own selection.
- Move myStructGenId from Graphic3d_StructureManager to Graphic3d_GraphicDriver for identifying the structures in the driver.
- Move default variable (no shading light) from static value to the class field of OpenGL_View.
Porting note:
- Static methods of AIS_Selection is not used now. Methods of
AIS_InteractiveContext::InitSelected(),::MoreSelected(),::NextSelected()
should be used instead of static methods of AIS_Selection.
- 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
- picked or selected objects are now highlighted via owners instead of interactive objects;
- support methods for owners were added to AIS_InteractiveContext;
- dynamically highlighted owners are now displayed in immediate mode;
- selection without opening of local context is enabled by default;
- added "-local" key to vselmode command to enable selection in local context;
- selection filters are now completely supported in AIS_InteractiveContext;
- the idea of differencing of selected items onto current (in interactive context) and selected (local selection) was eliminated;
- all calls to "current" were replaced by calls to "selected" in terms of future local context removal;
- AIS_InteractiveObject::mySelectionMode was removed;
- now each selectable object can define own selection mode for "global" selection of the whole object;
- whole object selection mode is 0 by default for all standard interactive objects;
- immediate structures are now added to topmost and top layer lists;
- added support of drawing immediate structures in different layers;
- unused code for immediate mode was removed;
- vfeedback and vexport commands now produce correct output for raytrace mode.
1) New Graphic3d_TransformPers structure for defining parameters and algorithm methods, featuring:
a) application of transformation to projection and world view matrices;
b) computation of model-world transformation of persistent object;
c) computation of transformed bounding box of persistent object.
2) Transform persistence algorithm does not make any changes to model-world transformation of object (deals with projection and world view matrices only), thus making possible to employ local transformation in a usual way.
3) Support of BVH selection for transform persistent objects (pan, rotate, zoom, trihedron persistence only).
4) Support efficient frustum culling for transform persistent objects (pan, rotate, zoom, trihedron persistence only).
5) Support of z-fitting algorithm for world-view space transform persistent objects (rotate, zoom persistence only).
6) Rewrite usage of transform persistence structures and utilities classes:
a) Replaced Graphic3d_CTransPers, TEL_TRANSFORM_PERSISTENCE by Graphic3d_TransformPers;
b) Move functions from OpenGl_Utils.hxx to Graphic3d_TransformUtils.hxx;
c) Extract matrix stack class from OpenGl_Utils.hxx to OpenGl_MatrixStack.hxx;
7) New class Graphic3d_WorldViewProjState to keep track of projection, world view matrices changes for a camera.
8) New test case bugs/vis/bug26344.
9) Renamed method Graphic3d_Camera::ModelViewState of to ::WorldViewState for consistency.
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()
Global static functions instantiating RTTI descriptors for class types (used though STANDARD_TYPE macro) are replaced by template static method Instance() of the class Standard_Type.
Implementation of RTTI is revised accordingly (global registry of type descriptors added to ensure single instance of each type descriptor shared by all dynamic libraries).
Obsolete methods of Standard_Type class (IsInstance(), Ancestors()) are removed; new method Parent() is added returning type descriptor of the parent class.
Class Standard_AncestorIterator is removed; this iteration can be easily done by recursive calls to Standard_Type::Parent().
Definition of macro STANDARD_TYPE() moved from Standard_Macro.hxx to Standard_DefineHandle.hxx.
Inclusion of Standard_Type.hxx and the class header is now necessary for use of method DownCast() and function STANDARD_TYPE() for the class.
In general, Standard_Type.hxx should be included now instead of Standard_DefineHandle.hxx in places where these macros are used.
Macro DEFINE_STANDARD_EXCEPTION changed to define all methods inline; macro IMPLEMENT_STANDARD_EXCEPTION becomes obsolete.
Macros IMPLEMENT_DOWNCAST, IMPLEMENT_STANDARD_* become deprecated, they are still defined (as empty) for compatibility.
Implementation of Handle classes became fully inline.
Method get() is added in Handle classes returning pointer to the contained object.
RTTI removed from NCollection_Handle class.
Standard_Persistent is made empty descendant of Standard_Transient, instead of implementing its own hierarchy with reference counting.
Unused enumerations Standard_InternalType, Standard_WayOfLife, Standard_KindOfType are removed.
Global function HashCode() accepting Handle(Standard_Transient) is removed; HashCode() for Standard_CString with length should be used instead.
DRAW command dtryload is added for testing dynamic load / unload of the specified library.
New test perf fclasses bug24947 uses this command to measure performance of multiple (1000 times) loading / unloading OCCT libs on example of TKSTEP.
Methods V3d_View::FitAll and NIS_View::FitAll3d now take arbitrary bounding box as a parameter;
Option -selected added to vfit command to fit only selected entities in Draw;
F key press now fits selected objects if any by default.
Redesign of selection mechanism:
- implemented 3-level BVH tree for selection;
- selection now calculates in 3D space;
- intersection tests were moved to SelectMgr_BaseFrustum descendants;
- removed .cdl files in Select3D and .cdl related to selection in MeshVS;
- SelectMgr_ViewerSelectors are now shared between local and global contexts;
- transformations of sensitive entities are now stored in SelectMgr_SelectableObject only. Sensitive entities are independent from transformations, it is applied to SelectMgr_SelectingVolumeManager instance only;
- connected and multiple connected interactive objects are now represented by their child objects only for SelectMgr_SelectionManager;
- if interactive object has child objects, they will be stored as separate objects in SelectMgr_SelectionManager now.
- test cases bugs/vis/bug24623_1, bug24623_2, bug24623_3, bug24623_4 to test performance and memory issues.
1. "HilightDrawer" were added to SelectMgr_SelectableObject.
2. Static drawer in StdSelect_Shape was replaced by class member. It's value is taken from special HilightDrawer of Selectable() object.
3. Computed relative deflection is stored as absolute deflection to be used for sub-shapes.
4. The ColoredShape object was updated to use for sub-shapes relative deflection computed for main shape.
5. Test case was added.

Added new toolkit TKIVtk:
- TKIVtk toolkit includes IVtkVTK, IVtkTools, IVtkOCC, IVtk packages.
- TKIVtk provides OCC interface for VTK library functionality: it allows to use VTK window and event managment for OCC objects (shapes)
Porting on VTK 6:
- shape source inherits vtkPolyDataAlgorithm now (vtkPolyDataSource was removed form VTK as deprecated functionality).
- added factory auto-initialization in IVtkVTK_View
- remove using of deprecated methods of pipeline mechanism.
Get rid from warning in SelectMgr_SelectableObject. Removed firendship from SelectMgr_SelectableObject.
Corrected projector parameters for selection algorithm.
Removed unneeded picking algorithm modification.
0023422: Selection problems when using SetLocation.
0024756: AIS_ConnectedInteractive does not support nested AIS_ConnectedInteractive
0025103: Visualization - Regression in interactive detection
Each PrsMgr_PresentableObject has list of PrsMgr _PresentableObject called myChildren.
Transformation PrsMgr_PresentableObject applied to its children every time when its own transformation affected. This hierarchy does not propagate to Graphic3d level and below.
PrsMgr_PresentableObject send its combined (according to hierarchy) transform down to Graphic3d_Structure.
AIS_ConnectedInteractive and AIS_MultiplyConnectedInteractive are reused but behavior has been changed.
AIS_ConnectedInteractive now is an instance of object. It reuses geometry of connected object but have own transformation, material, visibility flag etc. This connection propagated down to OpenGl level to OpenGl_Structure. For this task old “connected” mechanism has been reused.
AIS_MultiplyConnectedInteractive represents assembly which doesn’t have its own presentation. Assemblies are able to participate is scene hierarchy and intended to handle a grouped set of instanced objects. It behaves as single object in terms of selection. It applies high level transform to all sub-elements since it located above in the hierarchy.
All AIS_MultiplyConnectedInteractive are able to have child assemblies. Deep copy of object instances performed when one assembly attached to another.
