A class used to provide [method PhysicsServer3DExtension._soft_body_update_rendering_server] with a rendering handler for soft bodies. Called by the [PhysicsServer3D] to set the bounding box for the [SoftBody3D]. Called by the [PhysicsServer3D] to set the normal for the [SoftBody3D] vertex at the index specified by [param vertex_id]. [b]Note:[/b] The [param normal] parameter used to be of type [code]const void*[/code] prior to Godot 4.2. Called by the [PhysicsServer3D] to set the position for the [SoftBody3D] vertex at the index specified by [param vertex_id]. [b]Note:[/b] The [param vertex] parameter used to be of type [code]const void*[/code] prior to Godot 4.2. Sets the bounding box for the [SoftBody3D]. Sets the normal for the [SoftBody3D] vertex at the index specified by [param vertex_id]. Sets the position for the [SoftBody3D] vertex at the index specified by [param vertex_id].
