Hey @makami,
Your post reminds me of this one from @misher, where I wrote some leads toward a workaround way to achieve what you want. Very much not a definite solution, but basically you can have several point cloud renderers displayed over each other. If you position them correctly using ZED360’s resulting configuration file data, you can have a kind of hacky prototype.
How you would have VR user walk in the scene is another matter entirely however, and is pretty much independent from the ZED SDK.
Best,
Jean-Loup
