The new map feature can be useful in a variety of applications. You can use it to:
- View 2D scans that have been converted/exported to a single cartesian point cloud
- Stitch these converted 2D scans together to make floorplans
- View 3D pointclouds produced by the upcoming 3D scanner
- Transform the 3D point clouds around in space (translation + rotation)
- Stitch multiple 3D pointclouds together and export them as a single merged pointcloud
- Open a 3D pointcloud or created floor plan and use it as a background while you overlay/visualize data from a connected sensor or a recording file.
More documentation for each of these application is coming, but this article should introduce you to the basics.
1. Navigate to the "Map" tab.
2. Press the "Add Pointcloud" button.
3. Select a 3D Cartesian pointcloud file. For now, the only supported import format is CSV.
4. Depending on the size of the file, it might take a few seconds to upload. You should see the point cloud appear in the visualizer, and a collapsible entry should appear in sidebar panel.
5. Expand the render settings by toggling the "Show Render Settings" switch.
6. Change the color Scheme to "Green". This will help to visually discern which points belong to which cloud when we add additional point clouds.
7. Enable the Transform controls with the toggle switch. You should see an interactive transform widget appear at the center of the point cloud.
8. Use the Transform controls from the visualizer window to move the point cloud around in space.
9. Add another point cloud to the map, by pressing the "Add Pointcloud" button a second time.
10. Select the next point cloud you'd like to add.
11. Depending on the size of the file, it might take a few seconds to upload. You should see the second point cloud appear in the visualizer, and another collapsible entry should appear in sidebar panel.
12. Use the transform controls for the second point cloud to move it into place.
13. Use the "Export Map" button to stitch both point clouds together into a single 3D point cloud file.
14. Specify a name for the file. The default extension will be ".csv", but if you specify a filename that ends in ".ply", the file will be saved in PLY format. Be aware that you cannot import PLY files at this time.
15. A pop up should confirm that the file was saved successfully.
16. Remove the existing point clouds by pressing the "Remove Pointcloud" button under each entry.
17. Let's go ahead and view the point cloud we just created. Press the "Add Pointcloud" button just as before:
18. Select the file we created (exported).
19. This file might take longer to load, but once it does you should see a single point cloud containing all the points from previous two point clouds.
20. Experiment with the Render settings to better view 3D data.
Try reducing Point Size Scale and selecting Gradient on Signal Strength for the Color Scheme. Then adjust the saturation limits to highlight discontinuities in geometry or material properties.
