XShow and XDisplay XDE require VISUALIZATION for correct work.
In some scenario DRAWEXE can generate a duplicates of the internal static singletons.
This means each dynamic library will have their own instance of the static singleton.
Update all direct library loading to use the XDE plugin mechanism.
This will ensure that the XDE plugin is loaded only once and that the correct instance is used.
Originally issue is reproduced only Linux with dlopen with "RTLD_LAZY".
Can be resolved additionally adding "RTLD_LAZY | RTLD_GLOBAL" for dlopen
Reading and writing of triangle_strips and triangle_fans has been corrected in RWStepVisual_RWComplexTriangulatedFace.cxx file. And corresponding corrections have been added to other files.
Added support of reading and writing of the triangulated_surface_set.
Prevented creation of tesselated geometry under the schemas different from AP242DIS.
test step_read corrected, switched parameter write.step.schema to AP242DIS in begin and back to AP214CD at the end

0029641: Mesher produce 'bad' result for extruded spline with given deviation coefficient
Added method BRepMesh_NURBSRangeSplitter::getUndefinedInterval() intended to compute checkpoint parameters for those NURBS surfaces which have no intervals at all. In this case number of poles is used to produce artificial regular grid which can be refined further. Add at least one midpoint for surfaces with one interval and only two poles.
Added BRepMesh_ExtrusionRangeSplitter and BRepMesh_UndefinedRangeSplitter derivatives from BRepMesh_NURBSRangeSplitter intended to handle special cases of extrusion surfaces and general surfaces with undefined parameters.
'MultiThread' field was added to structure RWGltf_DracoParameters for using multithreading.

Support of reading and writing tessellated geometry is added for the following STEP entities:
- triangulated face
- complex triangulated face
- tessellated shell
- tessellated solid
- tessellated shape representation
Models without BRep geometry (mesh formats like STL, OBJ and so on) are supported for writing to STEP.
New parameters are added to enable/disable tessellated geometry reading and writing:
- read.step.tessellated (On/Off/OnNoBRep) (On by default)
- write.step.tessellated (On/Off/OnNoBRep) (OnNoBRep by default)
OnNoBRep - tessellation is read/written only for entities for which there is no BRep representation.
Faces with poly triangulation are written in STEP as triangulated face entities with one coordinates list per face.
Only one poly triangulation per face (returned by BRep_Tool::Triangulation) is written to STEP.
Added PLY writing tools RWPly_CafWriter and RWPly_PlyWriterContext.
Added tool BRepLib_PointCloudShape generating point cloud from shape in two ways:

Image_Texture is now checked if it defines an additional offset within the file
to avoided copying an old glb file with embedded image files instead of extracting them.
Progress indication mechanism is refactored to support incrementing progress within multithreaded algorithms.
The class Message_ProgressIndicator is only an interface to the user application.
It accumulates the progress provided by progress scopes.
The counter is protected by mutex for thread-safety.
The new class Message_ProgressScope replacing Message_ProgressSentry should be used to advance the progress.
The scopes are nested to each other to reflect the nested nature of operations.
The new class Message_ProgressRange should be used to pass the progress to sub-scopes.
All OCCT algorithms involving progress indication have been updated to new API.
Improvements in Draw_ProgressIndicator:
- Separate console mode has been added in order to make possible to put the progress into std::cout instead
or in addition to the draw interpreter, instead of trigger option "-tclOutput".
- Treatment of Ctrl-Break signal has been added.
Now any operation can be aborted by Ctrl-C or Ctrl-Break keystroke.
Added new test case 'perf fclasses progr_par' for testing of parallel work of the progress.
Added new condition for first indicated element at Draw_ProgressIndicator::Show(),
because it’s more logical that at start progress starts at 0

PBR shading model requires OpenGL 3.0+ or OpenGL ES 3.0+ hardware.
Environment cubemap is expected to be provided for realistic look of metallic materials.
occLight_IsHeadlight() now returns bool instead of int.
Avoid using lowp for enumerations to workaround occLight_IsHeadlight()
ignorance on Adreno 308 caused by some GLSL optimizator bugs.
OpenGl_Texture::EstimatedDataSize() - fixed estimation for Cubemap textures.
OpenGl_Sampler::applySamplerParams() - fixed uninitialized GL_TEXTURE_WRAP_R in case of GL_TEXTURE_CUBE_MAP target.
Removed tight connections between data structures, auxiliary tools and algorithms in order to create extensible solution, easy for maintenance and improvements;
Code is separated on several functional units responsible for specific operation for the sake of simplification of debugging and readability;
Introduced new data structures enabling possibility to manipulate discrete model of particular entity (edge, wire, face) in order to perform computations locally instead of processing an entire model.
The workflow of updated component can be divided on six parts:
* Creation of model data structure: source TopoDS_Shape passed to algorithm is analyzed and exploded on faces and edges. For each topological entity corresponding reflection is created in data model. Note that underlying algorithms use data model as input and access it via common interface which allows user to create custom data model with necessary dependencies between particular entities;
* Discretize edges 3D & 2D curves: 3D curve as well as associated set of 2D curves of each model edge is discretized in order to create coherent skeleton used as a base in faces meshing process. In case if some edge of source shape already contains polygonal data which suites specified parameters, it is extracted from shape and stored to the model as is. Each edge is processed separately, adjacency is not taken into account;
* Heal discrete model: source TopoDS_Shape can contain problems, such as open-wire or self-intersections, introduced during design, exchange or modification of model. In addition, some problems like self-intersections can be introduced by roughly discretized edges. This stage is responsible for analysis of discrete model in order to detect and repair faced problems or refuse model’s part for further processing in case if problem cannot be solved;
* Preprocess discrete model: defines actions specific for implemented approach to be performed before meshing of faces. By default, iterates over model faces and checks consistency of existing triangulations. Cleans topological faces and its adjacent edges from polygonal data in case of inconsistency or marks face of discrete model as not required for computation;
* Discretize faces: represents core part performing mesh generation for particular face based on 2D discrete data related to processing face. Caches polygonal data associated with face’s edges in data model for further processing and stores generated mesh to TopoDS_Face;
* Postprocess discrete model: defines actions specific for implemented approach to be performed after meshing of faces. By default, stores polygonal data obtained on previous stage to TopoDS_Edge objects of source model.
Component is now spread over IMeshData, IMeshTools, BRepMeshData and BRepMesh units.
<!break>
1. Extend "tricheck" DRAW-command in order to find degenerated triangles.
2. Class BRepMesh_FastDiscret::Parameters has been declared as deprecated.
3. NURBS range splitter: do not split intervals without necessity. Intervals are split only in case if it is impossible to compute normals directly on intervals.
4. Default value of IMeshTools_Parameters::MinSize has been changed. New value is equal to 0.1*Deflection.
5. Correction of test scripts:
1) perf mesh bug27119: requested deflection is increased from 1e-6 to 1e-5 to keep reasonable performance (but still reproducing original issue)
2) bugs mesh bug26692_1, 2: make snapshot of triangulation instead of wireframe (irrelevant)
Correction in upgrade guide.
readstl syntax has been modified, so that it creates a single-face triangulation by default.
The argument "trinagulation" is no more supported.
The new argument "-brep" has been introduced to generate
a compound of per-triangle faces instead (old default behavior of the command).
Add check for empty triangulation when writing STL file to report error instead of creation of empty file.
STL reader has been improved to properly handle case of empty or small files, and Ascii files without EOL at the end.
