Im curious as to how this could be done for larger objects like buildings etc. What would the devices be?

This reminds me of the Esper Light Cage used for 3D scanning actors' faces to recreate them in films such as The Social Network. example: https://youtu.be/Oitr_eYcJk0?t=112

I wonder if this needs to occur in a standardized environment with consistent lighting. If lightning is not consistent among different scans, would it affect the final result?

@CharlesLiu02 Based on what I gathered during lecture and the slides, it only makes sense if the lighting is consistent and in a standardized environment because the other specifications of a spherical gantry are also very specific. Given the stringent constraints on the other factors, it would only make sense that the only variability in lighting would be from the lamp and not from the other factors in the environment. Here is a list of all the specific configurations https://graphics.stanford.edu/projects/gantry/design/specifications.html

@ShaamerKumar This can be perhaps done through a special quadcopter drone, where it would circle around the large object just like the gantry?

how do factors such as noise effect this process. If the cameras are looking at the same point but get different values, how will this contribute to the overall result of the image

On a similar note to Justin, wouldn't the placement of the camera arm affect the lighting on the object (due to reflections/etc). I guess in the worst case it might straight up block the lamp, but otherwise I don't know if the effect is significant enough to matter
