The orthosphere view mode blends the two hemispheres of the orthographic projection in :ref:`panorama mode <panorama-mode>` on top of each other to simulate a full celestial sphere. There are two profiles:

- **Orthosphere** -- the base mode, in which both hemispheres are blended on top of each other. Optionally, you can fill up the sphere with a material with a certain :ref:`refraction index <refraction-index>`. To do so, open the preferences dialog, go to the Graphics configuration tab and scroll down to the experimental section. You will find a "Refraction index" slider to modify it.
- **Orthosphere cross-eye** -- a stereoscopic (3D) cross-eye mode which lays the images for each eye side-by-side.


.. hint:: :guilabel:`ctrl` + :guilabel:`shift` + :guilabel:`j` -- Cycle between the different profiles.

.. hint:: :guilabel:`F7` -- Save the faces of the current cubemap to image files in the screenshots directory.
