Point cloud file format

• A point cloud file must have the .asc, .pcd or .ply extension.
• Each line in the file must list the X, Y and Z coordinates of a point.
• The coordinates must be separated by spaces.
• The coordinates must use a decimal point, not a decimal comma.

Scripting

The code below can be used to scale an imported point cloud. Select the point cloud and run the code, either by pasting it in the Python console, or by saving it as a macro and executing that macro.

from PySide import QtWidgets
import FreeCAD as App
import FreeCADGui as Gui

def scale_points(obj, scale_x, scale_y, scale_z):
    mtx = App.Matrix()
    mtx.scale(scale_x, scale_y, scale_z)
    pts = obj.Points.copy()
    pts.transformGeometry(mtx)
    obj.Points = pts
    App.ActiveDocument.recompute()

if Gui.Selection.getSelection():
    obj = Gui.Selection.getSelection()[0]
    if obj.isDerivedFrom("Points::Feature"):
        scale, ok = QtWidgets.QInputDialog.getDouble(
            None,
            "Scale point cloud",
            "Scale:",
            value=1.0,
            decimals=6
        )
        if ok:
            scale_points(obj, scale, scale, scale)
