    Default Building Overviews (Pyramids) for C3D possible?

    In ArcGIS and QGIS it's possible to create lower resolution copies of Images depending on the zoom level. They call it Pyramids.
    (See 3. here: https://www.gis-blog.com/how-to-spee...gis-rendering/)

    It makes zooming in/out wayyyyyy faster. For example, for twenty five 10cm aerial images, it was taking 16 seconds to refresh the view after a zoom out. With Pyramids, it's practically instantaneous.

    For example, for each .tif, it will create a .tif.ovr (overwiew) file.

    I now know about this to make working with images faster :

    But is it possible, with C3D, to use something similar to pyramids/overviews? Can it create it's own? Can it use the .ovr file created by QGIS?

    Update: Corrected typo: MAPOPTIONS to MAPIOPTIONS

    With the enthusiasm I see here, I conclude that its not feasible in C3D...

    I meant MAPIOPTIONS and not MAPOPTIONS previously, by the way.
