Hi Hugo

Unfortunately I can’t give you any updates from my side since I moved on to other challenges and haven’t tried out the newest version yet. If I do I will definitely let you know.

Thanks for your support and best regards

Hi @younesssss

Thanks for your feedback, I implemented it.

I can open and run SofaPython examples without errors, however STLIB is still causing trouble.
I tried opening the CableConstraint.pyscn example in the \SOFA_v20.12.02_Win64\plugins\SoftRobots\docs\examples\component\constraint\CableConstraint folder and got the following error:

Hi @younesssss, thanks for your reply.

So I would like to use python 2.7 since to my understanding many of the softrobotic tutorials are still using python 2.7.

I actually hadn’t manually added the stlib folder to my path yet.

However, in my STLIB folder from the binaries I do have ...\SOFA_v20.12.02_Win64\plugins\STLIB\python but not the python3/src you mentioned, and on the opposite I have ...\SOFA_v20.12.02_Win64\plugins\STLIB\lib\python3\site-packages, and not the python2 site-packages –> so there seems to be a mismatch here (unless I am looking in the wrong folders).
How would you proceed?

Thanks for your help
Steph

Hi Hugo, nice to hear from you in writing as well after watching you for some hours on youtube 😀

Thanks for the notification that the screenshots are not viewable, I will paste the error code in the following.

I tried to use the (Python2.7) SofaPython plugin with the following script of the SoftRobots tutorials


from stlib.scene import MainHeader, ContactHeader
from stlib.visuals import ShowGrid
from stlib.physics.rigid import Floor
from stlib.physics.rigid import Cube

def createScene(rootNode):
    """This is my first scene"""
    MainHeader(rootNode, gravity=[0.0,-981.0,0.0])
    ContactHeader(rootNode, alarmDistance=15, contactDistance=10)

    Floor(rootNode,
          translation=[0.0,-160.0,0.0],
          isAStaticObject=True)

    Cube(rootNode,
          translation=[0.0,0.0,0.0],
          uniformScale=20.0)

    return rootNode

however I get an STLIB(.scene) error. Do I need to manually download/add STLIB into some directory? I read in some other forum posts about out-of-tree and cmake in connection with STLIB but am not sure if I need to do that and if so how. I assumed it came with the latest SOFA version since it’s listed in the plugin manager.

Nevertheless, the minimal python script example you presented in the youtube tutorial:


import Sofa

def createScene(node):
	node.gravity="0 0 0"
	node.name = "root"

	childNode = node.createChild("Particle")

	childNode.createObject('EulerImplicitSolver')
	childNode.createObject('CGLinearSolver',iterations="200",tolerance="1e-09")
	childNode.createObject('MechanicalObject', template="Rigid3d", name="myParticle",position="0 0 0 0 0 0 1", showObject="1")
	childNode.createObject('UniformMass',totalMass="1")
	childNode.createObject('ConstantForceField', name ="CFF", totalForce="1 0 0 0 0 0")

works now (except a “scene radius must be positive – ignoring value” message)!

I assume we have to get above to run before potentially moving to Python3?

Thanks for your reply/help and best regards
