A black and white image of speleothems (secondary cave formations) in a cave created by 3D laser scanning. The scan is composed of about 40 million data points recorded each with xyz coordinates and a reflective value used to create a photo-like immage.The white spheres are used for refference. The picture was authored by geologists Renate Fenzlein (BSc), Ingo Bauer (Dipl. Ing.) and Stephan Kempe (Dr. Prof. of Pysical Geology) of the Institute of Applied Geosciences, Technische Universität Darmstadt.
