Expose interface of OpenGl_View (OpenGL graphics rendering methods) to client code
and collecting all high-level API methods of application views in V3d_View class.
1) Exposing interface of OpenGl_View:
The OpenGl_View inherits from new class Graphic3d_CView.
Graphic3d_CView is an interface class that declares abstract methods for managing displayed structures,
display properties and a base layer code that implements computation
and management of HLR (or more broadly speaking view-depended) structures.
In new implementation it takes place of eliminated Visual3d_View.
As before the instance of Graphic3d_CView is still completely managed by V3d_View classes.
It can be accessed through V3d_View interface but normally this should not be required as all its methods are completely wrapped.
In more details, a concrete specialization of Graphic3d_CView is created and returned by graphical driver on request.
Right after creation the views is directly used for setting rendering properties and adding graphical structures to be displayed.
The rendering of graphics is possible after mapping a window and activating the view.
The direct setting of properties makes obsolete usage of intermediate structures with display parameter
like Visual3d_ContextView and etc (the whole package of Visual3d become redundant).
2) Collecting all high-level API methods of application views in V3d package:
The patch includes elimination of Visual3d layer.
All of its methods that could be previously used by application are now exposed and should be accessed on the level of V3d entities.
- Introduced new class Graphic3d_CView.
This is a base class for render views.
Made possible to specialize concrete instances of the class by graphical driver.
- Moved all methods managing rendering views into interface of Graphic3d_CView.
The corresponding methods were removed from interface of graphical driver.
3) Eliminated Visual3d package:
- Logic of managing display of structures was put from Visual3d_ViewManager into Graphic3d_StructureManager.
- Removed Visual3d_View class. Logic of managing computed structures was put into base layer of Graphi3d_CView.
- Removed all intermediate structures for storing view parameters e.g. Visual3d_ContextView.
All settings are kept by instances of Graphic3d_CView
- Removed Visual3d_Light intermediate class.
All light properties are still stored in Graphic3d_CLight structure.
The structure is directly access by instance of V3d_Light classes.
- Moved all needed enumerations into Graphic3d package.
4) Update package D3DHost to new changes.
5) Update code of OCCT samples to new changes.
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
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
Graphic3d_Group is now abstract class and should be instantiated
using Graphic3d_Structure::NewGroup() method.
Graphic3d_CGroup has been removed.
The groups list is no more duplicated within Graphic3d_Structure and OpenGl_Structure.
Removed unused/duplicated fields from Graphic3d_Group.
Prs3d_Presentation - remove redundnant field myCurrentGroup.
PrsMgr_Presentation3d::Erase(), ::Clear() - avoid possible NULL dereference.
OpenGl_GraphicDriver/Graphic3d_GraphicDriver - group management methods have been removed
(moved to Graphic3d_CStructure and Graphic3d_Group interfaces).
Graphic3d_Group::GroupPrimitivesAspect() - copy IsEmission flag
Fix wrong iterator
Fix compilation issues
License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.
Introduce Point Sprites usage.
Graphic3d_Group - drop Marker(),MarkerSet() methods - markers should be drawn using AddPrimitiveArray.
Added new Draw Harness commands vcaps, vmarkerstest.
Polylines and polygons removed, now everything is based on PrimitiveArrays.
Added use of Graphic3d_ArrayOfSegments, some additional clean up in Graphic3d_Group.
Dead code elimination in AIS and V3d
Corrected compilation errors
Fixed grid presentation
Adding test case correction
