    We have some sensors like laser scanners that are not supported by reme.
    Is there a way we can use the volume to integrate data from these other sensors?
    We have the depth data from multiple views. How can we update a volume with this data?

    Hi Chris,

    yes that’s possible by using our SDK and a newly introduced feature that allows you to supply external data. See here:

    Hope this helps.

    Btw. if the camera offset between the images is rather large, you might want to disable local search and use global search rather. We use this in our point-and-shoot example:

    Thanks for the reply and example code.
    In some cases we actually get 3d pt cloud data instead of depth maps.
    Can the volume be used to integrate two or more 3d pt clouds?

    Hi Chris,

    currently you cannot use point clouds directly, but you can often transform your pointclouds to dense depthmaps. For example if you know what pixel relationships you can just use the z-coordinate of your points.

    We still have a need to create a reconstruction from a sensor that produces point clouds rather than depth maps.
    Has there been any updates or changes that would support this?

    Hi Chris,

    you could do this on your own. If you know the assignment from points (call them v for now) to pixels (call them p for now) and know the camera intrinsics, you could just form a depthmap by setting the depth at p to be equal v.z

    Best,
