The tile selector (4) is used to select a tile from a larger point cloud. The buttons in (5) are used for opening, saving a tile, reverting, etc.

Navigation in the Point Cloud

There are three colored vectors which in the tile-coordinate system correspond to:

• red vector for the x-direction
• green vector for the y-direction
• blue vector for the z-direction

In the console output you will see the tile-coordinates of the currently selected tile. For example, 200, -100, 50 denotes the tile at x = 200 (red direction), y = -100 (green direction) with tile size = 50.

Tile selection

As the whole point cloud contains billions of points, we use a tile to represent a small part of the point cloud. In the tile selection view on the left side, you can select square to load all point inside the selected tile. The currently selected tile is highlighted by a orange border.

The red line running through the tiles shows the path of the car driving through the scene.
