Dear @andrija987

Sorry for the delay. The organization of the SOFA Week 2021 is keeping us busy.

I thought again about your issue. The BeamLinearMapping is a mapping computing a non-linear interpolation between the rigid frames (see the code here). If you want to have a CubeTopology which curvature is locally discontinuous (90deg angles between beam 2 and 3) it will be interpolated following the function line 158. Using this BeamMapping you could try to change the orientation of the frame number 3:

    [23, 2, -2, 0,         0.41321628, 0,         0.91063291],

and replace it by the linear interpolation of the orientation of the frame 2 and 4.

Else, I wonder if you are not interested in a RigidMapping instead (no interpolation, just mapping cubes over a rigid frame). You can see the example for instance using the RigidMapping example.

Hope this helps.

Ola @benjamin !

Great news, it should very soon be released in open-source (in the sofa-framework GitHub account).
It will therefore be out, stay tuned!

Hey @jducrocq007

Since the topic is now well identified and open in a GitHub issue, I think we can close this topic and follow up in the issue. Is it fine for you?

In my case I ran :

wget https://github.com/ninja-build/ninja/releases/download/v1.10.2/ninja-linux.zip 

sudo unzip ninja-linux.zip -d /usr/local/bin/

sudo update-alternatives --install /usr/bin/ninja ninja /usr/local/bin/ninja 1 --force

Hey @benjamin

it would be a huge plus for the code definitely!
For contributing you will have to get the sources of the BeamAdapter plugin. Do you have access to it?

Hi @daserk

It’s strange. What is LRmodel ? Is it a node ?
The function getObject should work an example here if liver is a node and dofs is an object in this node (a MechanicalObject here):

liver.getObject("dofs").findData("position").value

Hey SOFA forum!

We’re almost in November now!
It’s definitely the time to register to the SOFA Week: https://www.sofa-framework.org/sofa-events/sofa-week-2021/registration/

Looking forward to having you among us!

Best wishes,

Hi @qdyuan4619

Have you looked at the forcefield example in the SofaPython3?

Else regarding restarting a simulation in python, @PierreShg may help on this. It could cool to have an example of this in the SofaPython3 plugin!

Hey @qdyuan4619

I was going to say from your first post, the SOFA_ROOT and PYTHONPACKAGE environment variables would be wrongly set.

You mean to load an image on the forum ? You must give a link to the image itself not the sharing google link.

Is this topic solved though? Shall we close it?

And guys, do not forget about the SOFA Awards!

Apply with your open contributions! Already 3 candidates…

Hi Bani

A solution is available in the PR #2155. It will soon be merged inside SOFA.

Best wishes,

Hi @vanisri

If you have the motivation you can migrate to v21.06.01 and see if this helps.
But when having the import stlib in a python script, it means that the scene is looking for python2 codes.
For python3, the import should be changed to import stlib3

Great thanks for the feedback @dst03251
Could you pull-request this change in SOFA? (contributing doc)

Thanks a lot!
Best wishes,

Hugo

[Hugo]

Damned I get the same error.
The SOFA loader seems therefore not to support the latest gmsh format.

I created a dedicated issue on GitHub.

I will keep you posted.

Hi @zainab-awada

The STLIB plugin is not under our management. The migration towards python3 (NOTE: you should rather use import stlib3) is currently being done. Therefore, you might have noticed uncomplete cover of the STLIB features (some scenes are still only python2 compatible).

Do not hesitate to report them here: https://github.com/SofaDefrost/STLIB/issues. It will help developers to upgrade the plugin.

Best,

Hugo

[Hugo]

Thanks @vanisri for your feedback.

Would there be a way to have access to your mesh file?

Hey @dst03251

Sorry I have not, but did you check out the example scenes:
– examples/Components/forcefield/HexahedronCompositeFEMForceFieldAndMass.scn
– examples/Components/mapping/HexahedronCompositeFEMMapping.scn

?

Hi @vanisri

Please provide us more insight about your problem:
– the file about which you are talking
– the full error log you are receiving
– you confirm you are using the v21.06 SOFA release?

Hi @arsalan

Sorry I never did such a communication setup. However, regarding the data format maybe @damien-marchaluniv-lille1-fr would be able to provide more insight than I do..
Damien any idea?

Hi @zainab-awada

It confirms that both SOFA_ROOT and PYTHONPATH are not defined.
Could you define them as detailed here for Windows: https://sofapython3.readthedocs.io/en/latest/menu/SofaPlugin.html#within-a-python3-interpreter (click on the Windows button)

And then, check again these paths as you did above:

echo SOFA_ROOT = %SOFA_ROOT%
echo PYTHONPATH = %PYTHONPATH%

[Hugo]

Yes and do not hesitate to PR them to the SoftRobots project @beichun!

Cheers

Hi @psomers @cereven

It will be a starting point, a basic python tutorial but though a very useful to start from!
Stay tuned guys 😉 do not hesitate to poke me here again in one or two weeks !

Hi @cereven

This piece of code does not crash on my end (with a few modif to make it a real script):

import Sofa

def createScene(root):
    root.addObject("LightManager", listening=True, shadows=True, softShadows=False)
    root.addObject("OglShadowShader", name="shadowShader")
    endo = self.root.addChild("Endoscope")
    light = endo.addChild("light")
    light.addObject("SpotLight", name='spotlight', direction=f"offset_engine.positions",
                                            lookat=True,
                                            cutoff=90,  # angle in degrees
                                           position=f"@{name}_camera_system.output_position",
                                            attenuation = "0.15",
                                            shadowTextureSize="128",
                                            exponent=1, shadowsEnabled=True)

However, OglShadowShader is a very old component because rendering is not any more performed within SOFA but rather within Blender or Unity. A tutorial should soon come out explaining how to do such a rendering in Blender !
