05aa616d6d 0028218: Visualization, Path Tracing - Redesign path tracing materials to support two-layered model
Existing OCCT path tracing engine used very simple additive material (BSDF) model, so it was possible to reproduce
behavior only of very basic materials such as metal, glass, or plastic. However, some important in CAD industry
materials like car paint or ceramic could not be modeled well. In this patch, OCCT BSDF was significantly improved
by replacing additive model with two-layered scattering model. Therefore, we have base diffuse, glossy, or transmissive
layer, covered by one glossy/specular coat. The layers themselves have no thickness; they can simply reflect light or
transmits it to the layer under it. Balancing different combinations of layer properties can produce a wide range of
different effects. At the same time, disabling the first (coat) layer allows to keep full compatibility with previously
supported scattering model. All new parameters are available via 'vbsdf' command.

Location of new sample for few material examples:
samples\tcl\pathtrace_materials.tcl

Fix shader compilation issue.

Fix test case sample_ball_alpha.

6e728f3b5c 0027974: Visualization, ray tracing - Improve ray tracing engine
* Multiple importance sampling for path tracing
* Improved light sources sampling (better handling several light sources)

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.

Fixed misprint in test cases bugs/vis/bug24623_3 and bug25532.

29e2c6d247 0022785: Draw Harness - add possibility to remove a text drawn by the command vdrawtext
AIS_TextLabel - new public class to display simple text labels (based on MyTextClass private class from Draw Harness).
ViewerTest::Display() - add more reliable replacement for VDisplayAISObject() with no viewer update flag.

vdrawtext command redesign:
- Use new AIS_TextLabel class instead of private MyTextClass.
- Take object name and allow to clear labels from the Viewer.
- Use parameter name + parameter value syntax instead of strict list of mandatory arguments.
- Use [0; 1] range for colors and accept names.
- Drop redundant argument "isMultiByte".
- Support argument -noupdate to skip Viewer update.

Update test cases to new syntax of vdrawtext.

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.

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.
