Point Cloud to Mesh Reconstruction

PLY, STL and OBJ are available.

Cloud files follow the configured retention window.

5–6 gives a quick coarse mesh, 8 is a balanced default, 10–12 is finest but slower and uses more quota — start at 8 and adjust.

Poisson reconstruction needs oriented normals. Tick "Estimate normals" and we compute them; PLY inputs with normals are used as-is.

Reconstruction is server-side heavy compute (Open3D Poisson) — higher depth and point caps take longer, usually 1–5 minutes; the page keeps polling for up to about 11 minutes before timing out (server-side processing is capped at 10 minutes).

Clouds above the max-points cap are voxel-downsampled first. Normal orientation runs only on clouds of 300,000 points or fewer — larger clouds skip that step (normals keep their input or estimated directions), so Poisson output may have locally flipped faces in extreme cases. Pre-orient large files in a desktop tool or lower the point cap.

Poisson reconstruction solves for a closed implicit surface, so in good conditions the output is watertight — but in practice it depends on point density and normal quality: sparse or noisy regions, misoriented normals and stray far-from-surface points can produce holes or artifacts. Start at depth 8 and inspect the result; use the Mesh Doctor tool to check and repair holes afterwards.

A conversion keeps existing geometry and only rewrites the file. Reconstruction infers a new triangle surface from the points themselves, so it needs oriented normals (tick "Estimate normals" and we compute them), and detail depends on the depth setting and point density. That is why it runs server-side on Open3D and takes minutes rather than seconds.

Those desktop tools are free and unlimited, but you must install them, learn the filter chain and have a machine with enough RAM for million-point clouds. This tool runs in your browser tab with nothing to install — the Poisson reconstruction happens on our servers, which is why it needs an account and cloud quota. If you already do reconstruction in MeshLab, keep it; if you want a mesh from a scan without setting up a toolchain, start here.

Cloud reconstruction is billed per job against your Pro quota and requires sign-in, because the compute runs on our servers. Viewing your point clouds stays free and local — the LAS/LAZ/COPC viewers open files in your browser with no upload. If you only need to preview, export points or filter a scan, the in-browser point cloud tools cover that without an account.
