Hi Albert,
for questions related to pure SOFA, I highly recommend to ask in the official SOFA forum instead: https://www.sofa-framework.org/community/forum/section/user-forum/developing-in-sofa/ Best, Stefan? ________________________________ Von: Albert Alises <[email protected]> Gesendet: Mittwoch, 23.

Hello, I have a problem related to the way we access the scene and nodes information via the C++ API of SOFA (from MITK). I have a simulation node, sofa::simulation::Simulation simnode; Based on that object, I want to access a specific node component of this simulation, that is an OglModel (a mesh loaded from an stl). What I want to do is modify the translation and rotation properties of this node. That can be done on the xml file defining the scene as: <OglModel template="ExtVec3f" name="oglModel6? translation="100 0 100? .. However, as I am using MITK integrated with sofa, I need a way to access and modify the scene using the C++ API, not the xml. Is there a way I can get the OglModel object and add/modify fields to it from the sofa::simulation::Simulation class? I get to the point where I get the SOFASimulation object from the mitk::Simulation one. SOFASimulation = simulation->GetSOFASimulation(); Then I get a child node and try to get the mesh object and cast it to a VisualModel which has an applyTranslation method. However this does not seem to work, what I want to do is setup the scene moving the mesh (not on simulation runtime) sofa::simulation::Node::SPtr ImplantNode = SOFASimulation->GetRoot()->GetChild("Implant"); sofa::core::objectmodel::BaseObject *object = ImplantNode->getObject("oglModel6"); sofa::core::visual::VisualModel* visualModel = dynamic_cast<sofa::core::visual::VisualObject*>(object); visualModel->applyTranslation(100,0,100); Is it a casting problem, reference ... I do not know how to modify the initial placement of the objects of the scene, and the SOFA C++ API does not provide any examples that I have seen. Thank You, Albert. Thank you very much, Cordially, Albert. ------------------------------------------------------------------------------ _______________________________________________ mitk-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/mitk-users
