- Provide DumpJson for geometrical, ocaf and visualization classes;
- Change depth parameter of DumpJson (constant is not obligate here)
- Introduce a new macro for transient objects to be called as the first row in DumpJson: OCCT_DUMP_TRANSIENT_CLASS_BEGIN. We need not put the class name in the macro, using get_type_name of Standard_Transient for it.
- change implementation of OCCT_DUMP_CLASS_BEGIN and OCCT_DUMP_TRANSIENT_CLASS_BEGIN. It is not an sentry more and it does not create a new hierarchy level. It appends a new row into the output stream: "className": <className>
- OCCT_DUMP_* does not require semicolon
- class header is included first in source files of TDataStd, TDocStd, TCAFDoc
1. new file Standard_Dump to prepare and parse Dump in JSON format for OCCT objects
2. some presentations cover the proposed dump functionality.
3. 'bounding', 'vaspects' has '-dumpJson' field to see the DumpJson result
4. Bnd_Box constructor with min/max points is implemented to use Dump of this class in Dump BVH_Box
5. Limitation (some classes of Graphic3d, Prs3d has not full filling for DumpJson)
SelectBasics_EntityOwner has been merged into SelectMgr_EntityOwner.
Unused property SelectMgr_EntityOwner::ResetLocation() has been removed.
SelectBasics package has been moved from TKService to TKV3d.
SelectBasics_SensitiveEntity has been merged into Select3D_SensitiveEntity.
Extended SelectBasics_PickResult structure by myObjPickedPnt field, which contained the value of the 3d point on the selected object.
Changed all Overlaps methods. Parameter theDepth replaced on object of the structure SelectBasics_PickResult. This approach will be able to add new fields to SelectBasics_PickResult structure without big changes in modules which contained Overlaps method.
Introduced new method AIS_InteractiveContext::ClearDetected() allowing
to reset the list of detected objects and clear dynamically highlighted
entity under mouse cursor after previous AIS_InteractiveContext::MoveTo().
vmoveto command has been extended with new argument -reset.
SelectMgr_ViewerSelector::updatePoint3d() - scale tolerance according to Camera defintion.
SelectMgr_RectangularFrustum::segmentSegmentDistance() now uses gp::Resolution() instead of Precision::Confusion().
All occurrences of Standard_EXPORT attached to inline methods in OCCT code are eliminated.
Some unused classes and C++ files producing no code are deleted.
The macros Status, Convex, Opposite, FillSolid (coming from X11 headers)
are now undefined in place of definition of methods with same name in OCCT headers.
The usage of variables with name Status is now avoided.
GL_GLEXT_LEGACY is now defined only if not already defined.
The macros AddPrinter (coming from WinAPI headers) is now undefined
within Message_Messenger class definition having method with the same name.
CurrentDirectory macro is now undefined in OSD_Process.hxx.
Several methods in Selection classes have been moved to header files for better inlining.
BVH_Constants - added new enumeration defining common constant values used with BVH trees.
BVH - replaced NCollection_Handle with Standard_Transient handle
in classes BVH_Properties, BVH_Builder, BVH_Tree, BVH_Object.
Defined global BVH-builders instead of allocating a new one for each object set.
SelectMgr_ViewerSelector - added new method ::SetEntitySetBuilder() defining
default BVH Tree builder for SelectMgr_SensitiveEntitySet.
Added new method SelectMgr_SensitiveEntitySet::SetBuilder()
for overriding default BVH tree builder.
Low-level selection algorithms has been improved to explicitly support 2D
transformation persistent objects. This patch generally touches:
1) SelectMgr_SelectableObjectSet - the lists of objects has been split onto three
subsets (regular, 3d-persistent, 2d-persistent). Each subset has individual BVH
tree. The algorithms are now have more flexibility to update only those trees
that is really required for actual camera state.
2) SelectMgr_ViewerSelector - explicitly supports Eye space selection operations
on BVH tree for 2d-persistent subset. Change of camera position does not
anymore affect acceleration data structure (BVH tree) of 2d-persistent selectable objects.
3) Other classes from SelectMgr have been fine-tuned to provide appropriate API.
Porting notes:
This patch touches very low-level selection classes. If the low-level features were used
the following modifications may need to be considered for porting:
1) Iteration over objects of SelectMgr_SelectableObjectSet should now
be implemented with corresponding Iterator class.
2) SelectMgr_BaseFrustum::ScaleAndTransform and derived classes return
Handle(SelectMgr_BaseFrustum) instead of NCollection_Handle<> type.
Small correction of test case for issue CR27739
SelectMgr_SortCriterion now stores detected SensitiveEntity and 3D point.
SelectMgr_ToleranceMap class definition has been moved out to dedicated file (from SelectMgr_ViewerSelector).
SelectMgr_ViewerSelector - the methods implementing class-as-iterator
Init(), More(), Next(), Picked() and InitDetected(), MoreDetected(),
NextDetected(), DetectedEntity() have been deprecated.
User should access detection results by using index.
New methods PickedData(), PickedEntity(), PickedPoint() have been added
for accessing auxiliary information about picked object in sorted order.
OpenGl_GraphicDriver::ZLayers() / V3d_Viewer::GetAllZLayers() now return
the layers sequence following rendering order (taking into account IsImmediate flag).
StdSelect_ViewerSelector3d::Pick() now sort result taking into account ZLayers flags.
Add a new method AIS_InteractiveContext::SetTransformPersistence, which sets transform persistence to object and selection.
Add a new method SelectMgr_SelectionManager::UpdateSelection, which re-adds selectable object in BVHs in all viewer selectors.
Add a new method SelectMgr_ViewerSelector::MoveSelectableObject, which moves object from set of not transform persistence objects to set of transform persistence objects (or vice versa).
Add a new method Graphic3d_TransformUtils::Convert, which converts gp_Trsf to Graphic3d_Mat4.
Remove the method PrsMgr_PresentableObject::SetTransformPersistence(flag, point).
1) Zoom persistence mode now fixes object in pixel coordinates and is independent on view size
2) Used gp_GTrsf instead of gp_Trsf SelectMgr_ViewerSelector to store Graphic3d_Mat4d
3) Zoom persisted objects changed behavior (become bigger) therefore test cases were updated according to new state.
4) Corrected scale for rectangular frustum
Updated test for manipulator
- initial transformation of triangulation is now applied to selecting frustum;
- switched from NCollection_Vec3 to gp collections to avoid conversions and usage of macros;
- calculation of frustum was refactored to reduce its build time;
- double pixel tolerances for selection were replaced by integer ones;
- switched to splitting along the main axis only in SelectMgr BVH selection primitive sets.
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.
- now custom pixel tolerance from vselprecision is added to default sensitivity of the primitive;
- unnecessary field mytolerance was removed from SelectMgr_ViewerSelector;
- test case for issue #26413.
Forward declaration of TCollection instances as classes are replaced by inclusion of corresponding header.
Cyclic dependencies between declaration of collection class and its item are resolved by forward declaring a class in collection header.
Max tolerance is now applied to all objects and entities by default;
if there is an entity with a lower tolerance, selecting frustum will be recalculated for it.
The ability to set sensitivity for each entity individually is moved to protected section of SelectBasics_SensitiveEntity
SetPixelTolerance from AIS_InteractiveContext now sets custom tolerance that is applied to all sensitives.
Added -unset option to vselprecision command to disable custom tolerances.
Test case for issue #26159
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.
