WebNov 18, 2024 · Hey, I think it is probably how you are scaling the unsigned 8 bit depth back to a float, it needs to be multiplied by the original z-range. This line scaled it down: depth_float = ((depth - depth.min()) / depth.ptp()) So you need to scale it back rather than just using the int value, using something like: sewing and craft storage https://consival.com
