 +**Scan** is an interactive software to build and edit a plant architecture from a TLS cloud.
 +
 +Reconstructing plant architecture from terrestrial laser scan point clouds is needed to build detailed plant mock­ups useful for agronomists,​ botanists and forest scientists applications.
 +This issue is addressed by several methods [1] [2] [3] ​that are mostly automatic approaches. ​
 +However this issue remains a challenging problem because automatic methods can fail sometimes, for instance when missing zones in the point cloud result in discontinuous axes.
 +In the end, users often need an interactive tool to edit and complete the work with expert knowledge. We propose AMAPstudio­Scan,​ a software to build or edit plant topology and geometry by selecting interactive tools and clicking in the point cloud.
 +The software reduces the visible data resolution to keep the display of heavy point clouds responsive and proposes a feature to focus in a given spherical zone. 
 +
 +Topology is displayed over the point cloud and represented as a tree graph with vertices and edges. ​
 +Each vertex is defined by a disk (a center, a radius and a normal) and edges by two vertices and an axis identifier. ​
 +
 +To add a new vertex, the user draws a rough center and radius, then a strategy computes a fitted disk.
 +
 +Alternative strategies are proposed based on several approaches (e.g. ellipse fitting, ellipsoid fitting, projected convex hull).
 +A preview shows the selected vertex with its local point cloud and proposes extra interactive manual edition.
 +AMAPstudio­Scan is under development and aims at being complementary to the automatic methods by importing plant reconstruction from other software for edition. Finally, it’s possible to export to AMAPstudio­Xplo for structure edition, data extraction and 3D mesh visualisation.
