A method for optically scanning, measuring and displaying a point cloud is provided. The method includes emitting, by a laser scanner, an emission light beam and receiving a reflection light beam that is reflected from an object. A control device determines for measurement points projected on a plane corresponding to a screen, wherein at least some measurement points are displayed on a display device. One or more pixels are gap filled to generate a visual appearance of a surface on the display device. Wherein the gap filling includes a first horizontal search in a first direction of a first measured point of the measurement points followed by a second horizontal search in a second direction of the first measured point. The gap filling further includes a first vertical search in a third direction of the measured point, followed by a second vertical search in a fourth direction.
