How this works

Every visible layer is drawn; the active one (click its name) is what every tool works on. Double-click a name to rename it. Add file… opens another scan alongside this one — so does dropping a file with Shift held — while Open file… replaces everything. A tint multiplies a layer's colour so two overlapping scans can be told apart.

How this works

Moves the active layer onto the reference and never touches the reference. Match centres and Match scales are the coarse step; ICP is point-to-plane and lands on the reference's own surfaces. Distance to reference writes a scalar field on the active layer, so the colour ramp and the histogram show where the two disagree.

Shape

—

How this works

Click Create region then click a point on the cloud: a small shape appears there, ready to resize. Grow, the handles, the size sliders, or Alt + scroll while it is active all enlarge it; Fit to contents grows it until it stops finding new points and then tightens onto them.

Drag the arrows to move, the rings to rotate, the handles to resize. Double-click a point to move the orbit centre, then centre the region there. Keep inside dims everything outside the region; Remove inside dims what is inside it — either way the preview is what Apply will leave behind. Escape cancels the region.

Sections

—

How this works

Bounding shapes, combined as a union: keep only what lies inside any of them, or mark one Remove to drop what is inside it. A section is a slab you move, tilt and thicken with the gizmo — floors, a wall, a corridor. A drawn region (S) is an outline extruded along the direction you drew it from, so you can orbit around it and see exactly what it holds.

CloudCompare's SOR and noise filters, same settings, same points removed.

How this works

Remove outliers measures each point's mean distance to its neighbours and drops the ones beyond the mean plus Strictness standard deviations, judged over the whole cloud. A few very distant points can push that threshold out past the real outliers, so crop a stray reflection away first.

Remove noise fits a plane to the points around each point and drops it if it sits further off that plane than its own neighbours' spread allows. The threshold is local, so a smooth wall is judged strictly and a hedge loosely. Real edges survive because they still fit a plane.

Every removal is one undoable step.

GLOBAL SHIFT

—

How this works

Moves the whole cloud without touching a point. The records stay exactly as they are and a 4×4 matrix is applied when they are drawn, tested, analysed and exported — instant, lossless and undoable. Save a copy bakes it into the file.

The gizmo grabs the whole cloud at its bounding-box centre. It shares the handles with the crop region, so turning it on releases the crop gizmo and vice versa. One undo step per drag.

The scan's own pose offset, added back on export and shown in the coordinate readout. It is not part of the transform above and moves nothing on screen.

Components labels groups of points that touch within the spacing. Thin keeps one point per cube of that size.

—

How this works

A feature is one number per point, computed from the shape of its neighbourhood and written as a scalar field. Colour by it with Colour → Scalar field, or narrow the range to isolate part of the cloud.

How this works

A 2.5D volume: the difference between two height rasters over the same cells, one cell area at a time. Cut and fill are reported separately because their sum hides both.

How this works

Fits a primitive to the active region's contents, or to the whole layer when no region is active. The RMS is the number that says whether to believe it.

How this works

A field is one number per point. Colour by it with Colour → Scalar field, narrow the display range to see detail, or filter to keep only part of the cloud.

Opens a PLY, OBJ or STL as a layer of its own, to compare against or edit.

How this works

Build from points is surface reconstruction: it needs normals, and writes a triangle mesh as a separate object that you can show, hide, measure or export. Detail is the voxel size, so smaller is finer and slower, and below the scan's own point spacing it only adds noise. Fill gaps widens the band each point writes, closing small holes at the cost of rounding sharp edges.

Area and volume are measured through the layer's transform. A volume only means anything when the mesh is closed, so the boundary edge count is reported next to it. Smooth is Taubin with Keep volume on and plain Laplacian with it off. Decimate is vertex clustering at the cell you set, which is fast but cannot hit an exact triangle count.

Distance from this cloud measures every point of the active point layer to the nearest triangle of the mesh layer you pick, and writes it as a scalar field.

Your agent

Connect

How this works

The server is a WebSocket on 127.0.0.1:7337 that your agent starts and this tab connects to. Nothing is exposed off this machine. Chrome asks once to allow local network access.

The app is the server. It listens on 127.0.0.1 only and opens no other socket. There is nothing to download and nothing to switch on.

An agent on this bridge can do anything this panel can do, including deleting points and writing files. The Allow edits switch on the HTTP tab does not apply here. If you do not want an agent editing, do not register the server.

Click two points. M toggles. Single-click anywhere shows coordinates.
