b9f43ad13b 0031505: Point Cloud Rendering - fix on-screen statistics about number of visible points
OpenGl_Element now provide methods ::UpdateMemStats() and ::UpdateDrawStats()
for unified request of statistics used by OpenGl_FrameStats instead of direct handling of OpenGl_PrimitiveArray.
Graphic3d_FrameStatsCounter counters list has been extended by Graphic3d_FrameStatsCounter_NbLinesNotCulled.

3d60d73f76 0031394: Visualization, TKOpenGl - define OpenGl_Element::EstimatedDataSize() interface
OpenGl_FrameStats::updateStructures() now relies on OpenGl_Element inteface
instead of handling OpenGl_PrimitiveArray specifically
for collecting Graphic3d_FrameStatsCounter_EstimatedBytesGeom counter.
OpenGl_PrimitiveArray and OpenGl_Text implement new interface.

bc73b00672 0031313: Foundation Classes - Dump improvement for classes
- 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

1b661a81d5 0029874: Visualization - capping plane transparency does not work
Interface OpenGl_RenderFilter and its implementations have been merged into OpenGl_Workspace.
This limits flexibility of interface, but simplifies logic.
- OpenGl_RenderFilter_FillModeOnly flag replaces OpenGl_CappingAlgoFilter;
- OpenGl_RenderFilter_NonRaytraceableOnly flag replaces OpenGl_RaytraceFilter;
- OpenGl_RenderFilter_OpaqueOnly flag replaces OpenGl_OpaqueFilter;
- OpenGl_RenderFilter_TransparentOnly flag replaces OpenGl_TransparentFilter.

OpenGl_CappingAlgo now:
- avoids redundant Stencil clearing when Layer contains at least one transparent Element;
- renders semitransparent capping plane within transparent elements pass.

vclipplane command has been extended by new argument -transparency.

a1073ae267 0027925: Visualization - implement order-independent transparency algorithm within rasterization rendering
Weighted, Blended Order-Independent Transparency algorithm has been added rasterization pipeline.
In contrast to classical blending transparency it makes transparent objects look independent
from point of view. It also gives better depth occlusion when being used together with a weight factor
based on value of a GL depth buffer. The feature supports desktop OpenGL, OpenGL ES 3.0, ANGLE
and can be used together with MSAA on desktop GL.

To be used it require availability of:
1) Shaders pipeline.
2) Floating point color format for framebuffer (GL_ARB_color_buffer_float).
3) Multiple render targets (GL_ARB_draw_buffers).

Patch does not modify API and does not require application porting.
It adds new rendering options to Graphic3d_RenderingParams structure:
a) Transparency method from enumeration.
b) Scalar factor [0-1] controlling influence of a fragment's depth to its visibility.

Patch also simplifies processing of transparent objects for standard method:
rendering priority of transparent graphical structures is managed automatically,
therefore there is no need to care about it at application's side.

c04c30b3ee 0024023: Revamp the OCCT Handle -- general
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()

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

tests/bugs/vis/bug22906 migrated to the new vclipplane syntax

a174a3c54f 0023457: Slow text rendering
Added class Font_FTFont wrapper over FreeType face

Unify collections methods NCollection_Array1, NCollection_Sequence, NCollection_Vector:
declare Upper, Lower, First, Last, ChangeFirst, ChangeLast methods for all these collections.

Added method NCollection_DataMap::Find() with check key is bound + retrieve value within single call interface.

OpenGl_Context::ReleaseResource() method now supports lazy release of shared resources.

Added class OpenGl_Font which implements textured fonts support.
Added class OpenGl_TextFormatter for text formatting using OpenGl_Font.

OpenGl_Text was redesigned to use OpenGl_FontFormatter.

OpenGl_FontMgr class was removed.
All methods related to text rendered removed from OpenGl_Display class.

OpenGl_Trihedron and OpenGl_GraduatedTrihedron classes were redesigned
to use OpenGl_Text.

OpenGl_PrinterContext instance was moved to OpenGl_GraphicDriver fields
(eliminated usage of global instance).

Added test cases into 3rdparty/fonts grid to check different font styles
and perform FPS tests (no automated results - requires manual analysis
or snapshots comparisons).

Removed unused CSF_FTGL dependency.
OpenGl_Text::setupMatrix - do not apply floor for myWinZ

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
FTGL do not reset texture matrix and corrupt text could be rendered if custom texture has not identity texture matrix.

5e27df788d 0023226: Extend OpenGl_Context to store map of shared GPU resources
OpenGl_Resource was slightly corrected and OpenGl_Element was extended
with Release method to manage GPU resources.

OpenGl_PrimitiveArray now uses new OpenGl_VertexBuffer class (requires OpenGL 1.5+).
Strange workarounds for feedback mode were removed.

OpenGl_Context now provides access to shared GPU resources
and manages resources queue for delayed release
(replaces functionality of removed OpenGl_ResourceCleaner).
Loaded GL_ARB_texture_buffer_object and GL_ARB_draw_instanced extensions.

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.

New classes NCollection_Vec2, NCollection_Vec3 and NCollection_Vec4
implements interface to low-level data (points, vertices, colors) in GLSL-style.
Removed EnableVBO argument from vdrawparray Draw Harness command
Corrected compilation errors
Fixed wrong argument in Index VBO initialization
Fixed several cases of incorrect memory management in TKV3d

Visual3d_ViewManager::Remove()
Destroy structures before last view removed for correct GPU resources management.

Graphic3d_Structure::GraphicClear()

V3d_View::Remove()
Fixed mistake in #0000280 patch.
Small correction
Fixed OCC280 test command

Replace removed view within created one in ViewerTest EventManager.
ViewerTest, do not create unused 3D view

In current design NIS_View always created and used for both - NIS objects and AIS objects.
