Figure 9
The image is a partial view taken from beneath a large, dark rock surface, possibly the roof and wall of a cavern or tunnel. The rock occupies most of the left and upper parts of the frame, with an irregular, rough texture. Small colored dots, mainly red with some green and blue, are scattered over the rock, and many red streaks extend outward, suggesting marked scan or measurement points. On the right side of the image, beyond the edge of the rock, there is a bright outdoor scene with a blue sky, white clouds, distant hills, and a green field, creating a strong contrast with the shadowed interior foreground.Point cloud visualisation in a virtual reality environment.
