In which case the SLAM method is used ?

Question

Hello, I am doing a study related to the field of augmented reality, and especially related to Google's ARCore technology. I would like to know if the SLAM method is required for model-based tracking. It seems obvious to me that it is not used in this case, but I could not find any article to confirm this.
My second question is similar to the first one and is related to the Azure Spatial Anchors technology. This technology has the ability to recognize a scene that has been visualized during a previous session. In a way, the Azure Spatial Anchors technology reminds me a little bit of the model based tracking technology, knowing that the model based tracking has the ability to recognize a 3D object that has been previously recorded. So, in the same way I was wondering if the use of the Azure Spatial Anchors technology requires the use of the slam method ?
I can not find any information on this subject and I would be very grateful if you could enlighten me on it. Thank you in advance.

Hi @Kastler , I'd like to also refer you to Azure Spatial Anchor's FAQ page, especially the section How does Azure Spatial Anchors work?" (https://learn.microsoft.com/en-us/azure/spatial-anchors/spatial-anchor-faq#how-does-azure-spatial-anchors-work-). Hope that the information helps.
