In SOFA simulation window press “O” and that will create 2 files in your current directory(the folder where your .scn file was) open those files with notepad and one of them will show all the vertices and other values related to vertices of the object. Change the name of those files, run your simulation and at whatever time during simulation you need deformed vertices, stop the simulation, press “O” the 2 files will be created again, change their name if you need to get more new positions of vertices.

I used this scene there is just one sphere in it with 12 vertices, I deleted constraints from the scene and made the object fall under gravity when I press “O” in simulation at initial position and after some time, temp1_0000.MTL and temp1_0000.OBJ files were created in same directory both times(file name remains same that’s why changing name is important otherwise the same files are just updated), then I plotted those points with alphabet v in start in MATLAB to confirm this using scatter3(x,y,z) command and the results seem right.Zargham
sorry, I think I should elaborate what I mean by STRETCH, like when it is stretched it will elongate but it can show just a little bit of retraction but it shouldn’t go to it’s original position, it should stay deformed as how ever caused by the gripers or something.
Okay, thanks for that and sorry I had to go somewhere.
Anyway, can anyone tell me which components do i need to create an object which can stretch and deform but maintain its volume and can interact(collide and can be grabbed) with other objects? Doesn’t really matter what shape it has.BTW really thank you for all the help people 🙂
Modeler keeps crashing when I try to change the values(/GitHub/sofa/examples/Tutorials/StepByStep/FullObject/8_FullObject I’m changing gravity in Object node). It happened before too(in another tutorial) but I ignored it that maybe system got overloaded. So I chose “debug the program” and that’s what it shows in the output
“Unhandled exception at 0x000007FEEEEF7AC4 (SofaSimulationCommon_1_0.dll) in Modeler.exe: 0xC0000005: Access violation reading location 0x0000000000000008.”
so what should I do?
Okay so I compiled it in release and it still needed .dll files from sofa/tools/qt4win/bin. Anyway, I copied all those .dll files for release(ones without the alphabet ‘d’ at the end) and pasted them in buildfolder/bin and then it worked fine.
Also there was no Modeler.exe so I started over and then I compiled the Sofa.sln, copied the .dll files in bin folder and then runsofa.exe and Modeler.exe worked fine.Thank you so much for you patience and help Mr. Forest and Mr. Talbot.
Okay one last question now, which software(s) is the best to make .obj, .msh(.mesh and .mtl files are also used but they are all for meshes so I think any format should work but if there is more to it then please, do tell), .bvh, and .sph files?(there were some more files too but I haven’t used them yet so I don’t know even if I need them) Which software(s) do you people use for that creating these files?
I did read that other thread about .obj and .msh files, creating .obj from one software and then using sofa for meshing, I’ll try that but if there is some better way to deal with all this I would like to know.Once again, thank you people, you were a huge help.
I also tried with 32bit configurations and files, followed all the steps but for that when I execute runsofa.exe it says “libgcc_s_dw2-1.dll” file is missing.
I found the dll file in cloned git (C:\Users\User\Documents\GitHub\sofa\extlibs\SuiteSparse\cholmod\Lib) and added it to bin folder in build directory but now “QtCored4.dll” is missing.
I added that too from the cloned git (C:\Users\User\Documents\GitHub\sofa\tools\qt4win\lib) but it says “The procedure entry point _Z10qvsnprintfPcjPKcS_ can not be found in the DLL QtCored4.dll.” when I try to execute runsofad.exe
So I’m stuck again, I don’t know how to fix it and even google doesn’t have anything on that.
Okay so I used QT for 64 bit and everything worked fine while compilation(1 build was skipped though==> ***Skipped Build: Project: ALL_BUILD, Configuration: Debug x64 ——
1>Project not selected to build for this solution configuration ***) and a bin folder was created and there was a “runsofad.exe” file there. I tried to execute the .exe file but “Qt3supportd4.dll” was missing, so I tried to download it from here==> http://www.opendll.com/index.php?file-download=qt3supportd4.dll&arch=32bit&version=4.6.2.0&dsc=#
and copied it in “bin” folder and when I tried executing runsofad.exe file again, it gave 0xc000007b error, probably because .dll file is for 32 bit systems, so what should I do?
I tried finding a .dll file for 64 bit system but they were all for 32 bit and some were saying to just copy it in C:/windows/sysWOW64 for 64bit system.
These errors appeared after compilation(running Build Solution), also there is still no runsofa.exe file so I think these errors must be fixed for that. So how do I fix these errors?

********************************************************************************************Almost 70% of the warnings are “warning C4267” So kindly also give them a look if any or all of those need to be fixed.
Sorry, I know I’m asking a lot but I tried working with “SOFA 1.0.4”, it is not capable of what I want and it was released in 2010 if I’m not wrong, so it’s not up to date and it did feel like new plugins and components are much more advance. I really appreciate your help.
No no, there is nothing to be sorry about.
On step7 there were 3 warnings(that same old This warning is for project developers. Use -Wno-dev to suppress it.)

*********************************************************************************then I opened runsofa.sln and it started “parsing the files” then “scanning #inculdes for additional files” then “parsing included files” then “scanning #inculdes for additional files”… after several times of scanning and parsing files the solution is ready but I don’t know how to compile the solution, can you guide me about that too, please?
Sorry but I don’t know how to check that variable.
When I configure sofa using cmake, nothing named QT_QTCORE_INCLUDE_DIR appears.I downloaded QT 4.8.5 from http://mirrorservice.org/sites/download.qt-project.org/archive/qt/4.8/4.8.5/
and used qt-win-opensource-4.8.5-mingw.exe file to install it. Also I downloaded qt4.8.5 (64-bit) binaries from sofa site and extracted them in source directory. Which QT headers do I need to install and where can I get them from?If you want me to start from scratch, just follow your instructions, download and install everything from wherever you say I can do that too(If you think that’ll be better than debugging everything over here)
These files weren’t found during configuration

Should I go forward for compilation and what are the steps for it? (No, I couldn’t launch the compilation before, there was no option for it)
I was just testing BlenderSOFA using it’s given examples that it might work better but when I tried to export that “marbles” example in it, the scene was totally different and the objects had different constraints and if i can recall correctly there was just one marble in the exported scene.
