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
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.
