1.Why can't CUDA-accelerated PointCollisionModel be created successfully？2.why the addition of CarvingManager components to CUDA-accelerated TriangleCollisionModel is ineffective? Are there any good solutions?

Object type PointCollisionModel<> was not created
The object is in the factory but cannot be created.
Requested template : CudaVec3f
Used template : None
Also tried to create the object with the template 'Vec3d' but failed for the following reason(s):
1. No mechanical state with the datatype 'Vec3d' found in the context node.

Hello !

You might replace the PointCollisionModel by CudaPointCollisionModel. But in the end this will not speedup the collision detection process: it will still be performed on CPU because no GPU implementation exist. It might be best to map a Vec3 model (CPU DOFS) to your cuda model and add a PointCollisionModel to this mapped model.

Good luck with that !

I am very sorry for replying you so late. I did not explain many things clearly before because I was very unfamiliar with sofa. Now I have an example here. After I add template="CudaVec3", The TriangularFEMForceField<> was not created. Is there a solution to this error?
Thank you again and my best regards!

    <TriangleCollisionModel />

The cuda implementation of TriangulaFEMForcefield is called TriangularFEMForceFieldOptim could you try this to see if it works.

For the collision model I aready gave you an answer. But if you still want to have a collision model on your GPU dofs, you'll need to use the CudaXXXCollisionModel by replacing XXX by the type of ollision you want in the available ones : {Point, Line, Sphere, Triangle}

Can you see my picture messages? I tried to follow your advice, but it didn't work.

Sorry to bother you, but I am now faced with an incomprehensible phenomenon: when I added a model to the original scn file, the sofa effect of the original model changed a lot, and I did not change any of its parameters.What is the reason for this?
