Select an... ## [Manual Classification](https://rcdocs.leica-geosystems.com/docs/cyclone-3dr-cloudmanualclassificationc.md) Published on 2026-09-07 This command is used to select points from cloud(s) and classify them. Requirements Select all of the clouds you want to handle and launch the command (without any selection, you will edit all visible... ## [Distance](https://rcdocs.leica-geosystems.com/docs/cyclone-3dr-explodebydistancec.md) Published on 2026-09-07 This command splits cloud(s) into a group of clouds based on the distance between points. Requirements Select at least one cloud and launch the command. Define the Segmentation distance . This option... ## [Scan Stations](https://rcdocs.leica-geosystems.com/docs/cyclone-3dr-explodebyscanstationc.md) Published on 2026-09-07 This command splits cloud(s) and groups, all points related to the same scanning position, in a same cloud. If some points do not contain scanning positions, they are all merged in one cloud with the... ## [Real Colors](https://rcdocs.leica-geosystems.com/docs/cyclone-3dr-explodebycolorc.md) Published on 2026-09-07 This command splits cloud(s) according to the real color on each point. Points having a color similar to the selected one will be grouped in a point cloud. For example, you can use this command to... ## [Scan Patches](https://rcdocs.leica-geosystems.com/docs/cyclone-3dr-scanpatchesc.md) Updated on 2026-10-02 | Published on 2026-09-07 This command splits a point cloud into individual scan patches corresponding to the original scanning passes. It is particularly useful for inspecting, isolating, or removing specific acquisitions... ## [Noise](https://rcdocs.leica-geosystems.com/docs/cyclone-3dr-removenoisec.md) Published on 2026-09-07 This command filters sparse points inside cloud(s) having (or supposed to have) an approximate constant density. Requirements Select at least one cloud and launch the command. If several clouds have... ## [Moving Objects](https://rcdocs.leica-geosystems.com/docs/cyclone-3dr-movingobjectsc.md) Published on 2026-09-07 This command filters points corresponding to objects which were supposed to be moving while scanning. Requirements Select one or several clouds containing scanning positions. At least 2 scanning... ## [Angle](https://rcdocs.leica-geosystems.com/docs/cyclone-3dr-cloudseparatewithanglec.md) Published on 2026-09-07 This command filters points inside cloud(s) according to the angle between the estimated normal and the scanning direction of each point. Requirements Select at least one cloud containing scanning... ## [Distance from Scanner](https://rcdocs.leica-geosystems.com/docs/cyclone-3dr-restrictrangefromscannerpositionc.md) Published on 2026-09-07 This command filters points inside cloud(s) according to a range of distance from scanner values. Requirements Select at least one cloud containing scan positions and launch the command. Adjust the... ## [Split Ground Points](https://rcdocs.leica-geosystems.com/docs/cyclone-3dr-splitgroundpointsc.md) Published on 2026-09-07 This command allows you to extract the terrain from a point cloud, by creating a point cloud based on the ground points without vegetation or buildings. Requirements Select the point clouds... ## [Walls and Floors](https://rcdocs.leica-geosystems.com/docs/cyclone-3dr-splitwallsandfloorsc.md) Published on 2026-09-07 This command splits points of a cloud into 3 or 4 categories: Walls, Floors and ceilings, Others. Requirements Select the point clouds to split and launch the command. Set the angular tolerance for... ## [Clean-up Tunnel](https://rcdocs.leica-geosystems.com/docs/cyclone-3dr-cleanuptunnelc.md) Published on 2026-09-07 This command allows you to create a mesh based on the points located on the walls and on the ground of a tunnel point cloud. You can also use it to clean a tunnel point cloud. For example, this... ## [Resample](https://rcdocs.leica-geosystems.com/docs/cyclone-3dr-resampletotargetdensityc.md) Published on 2026-09-07 This command allows to keep points regularly spaced on cloud(s). Requirements Select at least one cloud and launch the command. Set the value for Average distance .
