Viewpoint

The Viewpoint module is used to preset key observation points and automatic roaming paths in the scene. It supports three types: Tour / Roaming / Area Viewpoint.

Note: Viewpoint data in the current version is not compatible with older versions. If you open a project containing legacy viewpoint data, the system will prompt that the data cannot be read and needs to be recreated.
