where is the introduction of buildModelsFromUrdf?

model, collision_model, visual_model = pin.buildModelsFromUrdf(urdf_path, mesh_dir, pin.JointModelFreeFlyer())
model: pin.Model = pin.buildModelFromUrdf(urdf_path)

I think that the above two model is different,so why?

Hello @LHTLiu,

First one will load urdf_path, mesh root dir should be in mesh_dir and the root joint will be a freeflyer.
Second one only load urdf_path and the root joint will be fixed.
