Zooming in and out
Use the scroll wheel on your mouse to zoom in or out of the pointcloud.
You can quickly change the camera view to one of the preset views using the tools from the left sidebar. There are preset camera views for Center, top, behind, left and right angles.
With distance attenuation turned on, you will see fewer points when you are far away from them. As you zoom in, more and more points will be visible. This can be a very helpful trick to label large point clouds on older computers. It is turned on by default if the point cloud is large (>500K points).
To change the point size of the pointcloud, click on the point size tool in the left sidebar, and use the slider to adjust the point size.
