Departing from traditional tree models made of cylinders (in green), sharper models (in blue) can be computed. Expressed as a continuous surface, they describe the shape better and allow to assess precisely the tree properties. The 3D samples and the surface model of a tropical tree can be visualize here

Sequence of processing steps: modelling of the terrain surface, detection of the tree stem, then estimation of the tree model. 3D model of a Mangrove tree (Avicennia germinans Copyright A. Olagoke and C. Proisy, 2014, IRD UMR AMAP)

Mesh model of an evergreen sub tropical tree (Erytrophleum fordii) based on SimpleTree.

3D Points clouds from Mahabalipuram (India) created with VisualSFM Ganesh Statue and the Descent of the Ganges previews on Sketchfab.

Example of shaded point cloud 1 - Load a colored point cloud in CloudCompare 2 - Use its PCV plugin to compute the ambient occlusion of the point cloud. Save the resulting point cloud as a ASCII file. 3 - Use the following command to apply the ambient occlusion to the RGB values : awk... Continue Reading →

"LiDAR VR Viewer" is an Android application freely available on the Google Play Store which dives the user into a virtual reality made of 3D point clouds surfaces.
