[Topology] Segfaults on topological changes

3

### Problem Hi, this is related to https://github.com/sofa-framework/sofa/issues/3201. Same as before, I want to cut a deformable object. I wanted to check, if it is easier in total to replace...

[Topology] Topological changes on HexahedronSetTopology and EdgeSetTopology Container

2

### Problem Hi, I would like to create scene where a `SphereCollisionModel` cuts - `HexahedronSetTopology` - `EdgeSetTopology` For the `HexahedronSetTopology`, there seems to be a bug in mapping the correct...

Topology changes for SphereCollisionModel on EdgeSetTopologyContainer

4

Hi, removing `SphereCollisionModel` elements from a `EdgeSetTopologyContainer` currently does not work, because `TopologicalChangeManager::removeItemsFromSphereModel` calls `getCollisionTopology` https://github.com/sofa-framework/sofa/blob/d42e3547dffaf385448fb077d466fc0bebc39bc9/Sofa/GUI/Component/src/sofa/gui/component/performer/TopologicalChangeManager.cpp#L297 which is not implemented in `SphereCollisionModel`, and the default from `BaseMeshTopology` returns `nullptr`. https://github.com/sofa-framework/sofa/blob/471a3df6a377f92155f34ab4a75e931ec9559f7f/Sofa/framework/Core/src/sofa/core/CollisionModel.h#L357...

### Problem If there is an `OglShadowShader`, the texture of an `OglModel` is not rendered. Bonus problem: The direction of a `DirectionalLight` is also flipped. If I take the [OglShadowShader_Directional...

### Problem I played around with a pythonized version of the [BeamFEMForceField Example](https://github.com/sofa-framework/sofa/blob/4a5d3322e4155798799fc2c3c68b00ac2f00b154/examples/Components/forcefield/BeamFEMForceField.scn). ```python node.addObject( "CubeTopology", nx=num_points, ny=2, nz=2, min=[0, -0.1, -0.1], max=[length, 0.1, 0.1], ) node.addObject("MechanicalObject") node.addObject("TriangleCollisionModel") node.addObject("BeamLinearMapping", isMechanical=True)...

Error when training simdcl with batch_size > 1

Hi, I ran the following config, ``` python train.py \ --dataroot datasets/a_to_b \ --name a_to_b \ --model simdcl \ --no_flip \ --lr_policy linear \ --gpu_ids 0,1,2,3 \ --direction AtoB \...

Memory Leak related to unload and rendering

3

Hi, there is another memory leak, this time related to rendering in combination with `simulation.unload`. As a testing scene, I took the [pygame example from SofaPython3](https://github.com/sofa-framework/SofaPython3/blob/master/examples/additional-examples/pygame_example.py) and added a reload...

HexahedronCompositeFEMForceFieldAndMass Solver

5

### Problem Hi, the example for the [HexahedronCompositeFEMForceFieldAndMass](https://github.com/sofa-framework/sofa/blob/master/examples/Component/SolidMechanics/FEM/HexahedronCompositeFEMForceFieldAndMass.scn) complains, that ``` [WARNING] [HexahedronCompositeFEMMapping(HexahedronCompositeFEMMapping)] This object only support Direct Solving but an Indirect Solver in the scene is calling method applyJT(constraint)...

### Problem With the same exact parameters, `FastTetrahedralCorotationalForceField` shows unstable behavior, compared to `TetrahedralCorotationalFEMForceField`. **Expected behavior** I would expect both components to show the same behavior, or at least to...

CollisionGroup not updating value

15

Hi! :) I am trying to change the collision group of a collision model during runtime. However, the values are not updated correctly, and the `.array()` method returns weird values....
