[Bindings] Add bindings for Snapshot

[Lucas-TJ]

PR SofaPython3 - Snapshot

Snapshot_bindings

Related to sofa-framework/sofa#6168 (Do not merge before)

Overview

This Pull Request adds bindings for the Snapshot feature in SofaPython3. It provides a bridge between the Snapshot API in Sofa and Python, allowing users to save and load snapshots through Python bindings.

Currently, snapshots can only be saved and loaded in memory with bindings.

API

Snapshot_Python

Snapshot_Python is a class used to store snapshots through the m_snapshots vector.

Save and Load

To save and load snapshots, users can call executeSaveSnapshotVisitor() and executeLoadSnapshotVisitor(). These functions execute the corresponding visitors responsible for saving and loading snapshots.

The visitor is called directly on the "root" node and works in the same way as the standard Snapshot feature. The snapshot is stored in a previously initialized Snapshot_Python container.

Exemple

snapshot = Sofa.Core.Snapshot_Python

root.executeSaveSnapshotVisitor(snapshot)

root.executeLoadSnapshotVisitor(snapshot,0)
