a195430212 0024394: Visualization - implement more general way for rendering of immediate objects
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

7d9e854bdc 0025276: Visualization - Lighting is broken if some kinds of transformation applied to a shape
In order to solve the problem, triangle vertices order is inverted in
mirrored mesh (triangulation). Mesh considered to be mirrored if its
transformation matrix determinant is less than 0.

To handle AIS object mirror transformations "Mirrored" flag stored in
OpenGl_Structure. If this flag is enabled, glFrontFace (GL_CW) applied
before the draw call.

New DRAW commands for visualization level transformations added.

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.

AIS_InteractiveContext, AIS_LocalContext add flag to prevent view update into methods
::MoveTo(), ::HilightNextDetected(), ::HilightPreviousDetected()

StdSelect_ViewerSelector3d do not user immediate mode in methods
::DisplayAreas(), ::ClearAreas(), ::ClearSensitive(), ::DisplaySensitive(),

GridEcho - update value in StdSelect_ViewerSelector3d::Pick() instead of V3d_View::Compute().

e276548b09 0024130: Implementing ray tracing visualization core
The purpose of this functionality is to bring a basic ray-tracing solution to existing OCCT visualization toolkit (TKOpenGL).
Currently ray-tracing visualization core supports sharp shadows, specular reflections, transparency and adaptive anti-aliasing.
However, the basis for all ray-tracing algorithms is versatile, allowing you to add new ray-tracing features easily (such as ambient occlusion).
All ray-tracing computations are performed on the GPU using OpenCL framework, allowing real-time rendering performance.

It is important to note, that real-time ray-tracing is possible using high-performance GPUs with support of OpenCL 1.1 and higher (such as NVIDIA GeForce 660 or ATI/AMD Radeon 7850).
When using low-end GPUs (such as NVIDIA GeForce 640) the ray-tracing performance may slow down significantly.
Therefore, even with NVIDIA GeForce 640 you can render scenes with the millions of triangles. The support of OpenCL-enabled CPUs and integrated graphics cards is not guaranteed.

4269bd1b11 0024070: OpenGL capped object-level clipping planes
Graphical clipping:
- Use "Graphic3d_ClipPlane" to defined clipping for PrsMgr_PresentableObject (local clipping), for V3d_View (global clipping).

Get rid of old implementations:
- Remove Visual3d_ClipPlane.
- Port V3d_Plane to Graphic3d_ClipPlane core.

Selection Sensitives:
- Port "Matches" method to add full set of arguments (SelectBasics_PickArgs), including min-max depth coming from selector.
- Get rid of transient data for pair Matches -> ComputeDepth.
- Extend SelectMgr_ViewerSelector::LoadResult to work with local clipping, add virtual callbacks to compute globa/local depth clipping for picking.

Capping rendering algorithm:
- Recursive rendering algorithm for OpenGl_Groups.
- Introduced Rendering filter for groups.

Clipping plane management in TKOpenGl:
- Added OpenGl_ClippingState to OpenGl_Context.

DRAWEXE commands:
- Ported "vclipplane" command for new approach.
- Added "vsettexturemode" command for changing texture details in views (enable / disable textures).

Correct DownCast syntax (compilation error)

Fix new compiler warnings

bf75be9867 0023544: Texture management in TKOpenGl should be redesigned
Structures Graphic3d_CView, Graphic3d_CStructure, Graphic3d_CGroup become classes and their definitions moved from InterfaceGraphic to Graphic3d.
Introduced new class OpenGl_Texture as replacement for OpenGl_ResourceTexture class and static functions in OpenGl_TextureBox.
Graphic3d_TextureRoot now no more communicate within Graphic3d_GraphicalDriver.
Instead class returns image through GetImage() method.
OpenGl_AspectFace - avoid possible NULL-dereference
OpenGl_Texture::Init() - check gluBuild2DMipmaps() return value
OpenGl_Texture - check GL_BGRA_EXT for compatibility
OpenGl_Texture - scale NPOT image when required
Added more description to Graphic3d_TextureRoot class
OpenGl_Texture - added missing break statement for ImgBGR32 case
OpenGl_Workspace::setTextureParams() - fixed local variable aFilterMin overrides visibility of early declared variable
OpenGl_Workspace::DisableTexture() - reset texture matrix

Global maps of views, workspaces and structures
were moved to OpenGl_GraphicDriver members.
UserDrawCallback() function moved to OpenGl_GraphicDriver methods.

Aspect_GraphicCallbackStruct now holds handle of OpenGl_Context
instead of system-dependent pointers to GL context definition.

Fixed wrong argument in Index VBO initialization
Fixed several cases of incorrect memory management in TKV3d

Visual3d_ViewManager::Remove()
