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.
Move OpenGl_Structure::myZLayer to base class Graphic3d_CStructure.
Graphic3d_ZLayerId - introduce new pre-defined ZLayers.
Do not clear Depth buffer twice for default ZLayer.
AIS_InteractiveContext::Display() - add new argument AIS_DisplayStatus to specify displaying status.
Drop unused Graphic3d_CPick and related methods.
Drop OpenGl_Structure::myNamedStatus - use flags from parent class Graphic3d_CStructure directly.
OpenGl_LayerList ::ChangeLayer(), ::ChangePriority - fix structure remove from unexpected layer.
Merge class OpenGl_PriorityList into OpenGl_Layer.
PrsMgr_PresentationManager::mySelectionColor - store selection color as field of Presentation Manager.
PrsMgr_Presentation class - do not declare private methods as virtual.
PrsMgr_Presentation::Highlight() - extend method syntax and drop methods ::Color() and ::BoundBox().
PrsMgr_PresentableObject - store ZLayer in presentable object
to display object presentations in required layer directly
(without displaying it in wrong layer first).
test/mesh/end - force re-displaying the shape to compute mesh anew
Test-case for issue
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.
Correction test cases for CR24837
Test cases for issue CR23422
Test cases for issue CR24756
Test cases for issue CR25103
Viewer3d sample fixed.
1) Add SelectMgr_EntityOwner::IsSelected() and SelectMgr_EntityOwner::SetSelected() methods to determine if corresponding entity is selected.
They replace functionality of SelectMgr_EntityOwner::State() methods that are deprecated now.
2) AIS_InteractiveContext::ToHilightSelected() and AIS_InteractiveContext::SetToHilightSelected() is to be used to enable highlighting of selected objects.
3) By default selected objects are highlighted (new behavior)
4) Add ViewerTest_ViewerCommands: vhighlightselected command to enable/disable 'highlight selected objects' mode.
5) AIS_LocalContext, AIS_InteractiveContext : style changes in Select and ShiftSelect methods.
6) Add test cases /bugs/vis bug23649_1 and /bugs/vis bug23649_2 to test highlighting of selected objects in local context.
7) Add test cases /bugs/vis bug23649_3 and /bugs/vis bug23649_4 to test highlighting of selected objects in neutral point.
