I was running out of RAM and out of swap while trying to generate a copc out of a laz with #pdal (the laz weighs 4.7GB). So I created a 15GB swapfile by simply adding

swapDevices = [{
device = "/var/lib/swapfile_15G";
size = 15*1024;
}];

to configuration.nix, rebuild, and voilà. The process is currently running very smoothly, peak consuming the whole RAM as expected (64GB) + 12GB out of the available 24GB.

New open‑source breakthrough: SAM3D can isolate individual objects—like a tall lamp—in a point‑cloud scene, far beyond coarse class segmentation. See how promptable segmentation lets you pick out a human, a chair, or any item in a Meta‑style 3D environment. Dive into the details! #SAM3D #PromptableSegmentation #PointCloud #TallLamp

I released an update to my libE57Format library—version 3.3—to fix some build warnings & to update the build system (cmake)🏗️.

It is a C++ library which provides read & write support for the ASTM-standard E57 file format on Linux, macOS, and Windows. E57 files store 3D point cloud data, attributes associated with 3D point data (color & intensity), and 2D images (photos).
