0d828ac838 0032208: Tests - refactor visualization tests to cover several graphic drivers
Removed testgrids 'bugs/vis' and '3rdparty'; tests have been redistributed across other grids.
Moved testgrid 'v3d/ivtk' into dedicated 'vtk/ivtk'.

Added testgrid 'vselect' dedicated to 3D viewer picking/selection functionality
and filled with tests from 'v3d/vertex', 'v3d/face' and similar groups.

Added testgrid 'opengl' dedicated to OpenGL driver low-level functionality (GLSL programs and similar)
and filled with tests from 'v3d/glsl', 'v3d/raytrace', '3rdparty/fonts', 'bugs/vis' (portion) and similar.

Added testgrid 'opengles3' dedicated to OpenGL ES 3.0 driver low-level functionality
and reusing tests from 'opengl' testgrid.
Subgroup 'opengles3/raytrace' is disabled on Windows, as Ray-Tracing currently requires OpenGL ES 3.2.
while ANGLE library implements only OpenGL ES 3.0.

Added testgrid 'opengles2' dedicated to OpenGL ES 2.0 driver low-level functionality
and reusing a limited subset of passing tests from 'opengl' testgrid.
Currently testgrid is activated only on Windows platform when using ANGLE library
(properietary OpenGL ES drivers do not allow creation of restricted 2.0 context).

Test cases have been cleaned out to put bug description into log,
to properly load necessary plugins and to explicitly dump viewer.

14b741b0ef 0031454: Visualization - perceptually uniform color scale
Support of CIE Lab and Lch color spaces is introduced in Quantity_Color:
- Enumeration Quantity_TypeOfColor is extended by new values representing CIE Lab and Lch color spaces (with D65 2 deg illuminant).
- Conversion of RGB color to and from these color spaces is implemented in Quantity_Color class (within existing API).
- Color difference calculation using CIE Delta E 200 formula is implemented in method DeltaE2000().

New methods MakeUniformColors() and SetUniformColors() are added in class AIS_ColorScale, generating and setting color scale based on colors of the same lightness in CIE Lch color model.

DRAW commands vcolorconvert and vcolordiff are added to perform conversions and compute difference, respectively.
A new option -uniform is added in DRAW command vcolorscale, to set uniform color scale.

Added test grid v3d colors (color conversions and difference), test bugs vis bug31454 (uniform color scale)

2108d9a25b 0028954: Visualization - implement interactive object for camera manipulations
Added new class AIS_ViewCube implementing interactive cube
displaying orientation of the main axes of the model space in the viewer.
Each side, edge, or corner of the cube corresponds to particular orientation of the camera,
and the class provides methods to move the camera to corresponding position (with animation if needed).

AIS_InteractiveContext::LastActiveView(), added new property returning the last View processed by MoveTo() event.
AIS_InteractiveContext::BoundingBoxOfSelection(), added method returning bounding box of selected objects.
SelectMgr_EntityOwner::HandleMouseClick(), added new callback for handling
mouse clicks by owner itself without automatic highlighting and clearing previous selection.
Called by AIS_InteractiveContext::Select() method.

AIS_ViewController::ViewAnimation() has been extened with camera animation propery,
which can be bound to AIS_ViewCube for smooth embedding into event loop.

Prs3d_ToolDisk has been extended with parameters specifying angle range.
Graphic3d_MaterialAspect now initializes all coefficients to 1.0
when Graphic3d_NOM_UserDefined is passed to class constructor.
AIS_AnimationCamera::update() now sets the end camera position if animation duration is 0.
Prs3d_DatumAspect, added missing setters.

New command vviewcube has been added.

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.

1beb58d745 0027764: Visualization - add functionality for animation of 3D camera and interactive objects
Added classes AIS_Animation, AIS_AnimationCamera, AIS_AnimationObjectLocatio.

Draw Harness command vanimation has been modified to manage animation timeline.
Command vfit has been extended with option -noupdate.
Formatting of vviewparams command output has been improved.
Functionality of commands vlocreset, vlocmove, vloctranslate, vlocrotate,
vlocmirror, vlocscale has been merged into vlocation/vsetlocation.
vlocation now can print the current local transformation of the object.

v3d/ivtk test group does not call vfit anymore.

625e195819 0027038: Visualization - add new presentation for object manipulation
AIS_Manipulator class has been created to provide interactive services for manipulating with mouse local transformations of other interactive objects.

The class features three kinds of transformation modes for attached objects:
- translation of through axis
- scaling within axis
- rotation around axis

For more details please have a look at description of the class in reference manual or in header file.

The patch includes DRAW test workbench for evaluating the AIS_Manipulator features.

52f99d93a9 0022877: Implementation of DRAW commands for non-regression testing:
- TKIVtkDraw toolkit provides IVtk packages functionality in DRAW.

- it allows to create VTK interactive view in regular or virtual mode (virtual windows),
  display OCC objects and dump them.

- TKIVtkDraw provides also test commands: ivtlinit, ivtkdisplay, ivtkerase, ivtksetdispmode,
   ivtksetselmode, ivtkmoveto, ivtkselect, ivtkfit, ivtkdump, ivtkbgcolor.

Corrected offscreen rendering mode.

Moved vinit command from /v3d/begin script to avoid unused occ view in ivtk tests.

44c7c33eb0 0024855: Revision of parameters of standard materials
Improve consistency and visual appearance of predefined OCCT materials in various rendering modes, including ray-tracing:
- Increase the specular exponents (shininesses) for metallic surfaces: Brass, Bronze, Copper, Gold, Pewter, Silver, Steel, Chrome, Aluminum.
- Revise specular colors for metals: Copper, Gold, Aluminum, Silver (according to "Real-Time Rendering, 3rd Edition", AK Peters 2008).
- Increase diffuse reflection of metals: Silver, Aluminum, Chrome (to make them brighter in OpenGL mode).
- Extend Material definition by Refraction Index.
  Advanced rendering methods based on shaders or ray-tracing can utilize it to produce refraction effects.

In addition:
- Introduce three translucent materials: Water, Glass, and Diamond.
- Add Charcoal for modeling dark diffuse surfaces.

Add new TCL-based sample (materials.tcl) and test case (tests/v3d/materials/bug24855).
