Fig. 3From: Phyllotaxis transition over the lifespan of a palm tree using Magnetic Resonance Imaging (MRI) and Terrestrial Laser Scanning (TLS): the case of Jubaea chilensisSmooth surface model of the stem produced from a TLS cloud of points. A The model consists of small patches; B to simplify the quantitative analysis, an approximate axis as a straight line close to the center of the stem, going from the bottom to the top was defined (red arrow), and each patch is represented by a single blue point. For illustrative purposes, we have increased the size of the patches of our surface modelBack to article page
