SURFACE module can be considered as a valid qualitative compromise between DRAW and MESH modules. DRAW module allows to construct the 3D model by the user’s interpretation of the point cloud. MESH module constructs the 3D model on the point surveyed by laser scanner (there is no interpretation by the user, unless in deciding how many points have to be preserved and their position after filters application). SURFACE module allows to “average” between the two methods, i.e. the user can interpret how to construct the 3D model by joining several subparts. Each subpart is computed automatically considering all the points of the cloud and creating a regular grid, whose quality is defined by the user. This feature of SURFACE module allows to obtain 3D models with a good detail, which is recommendable for representing the irregularities of almost flat surfaces, limiting the heaviness of the model itself. The model can be used to obtain contour lines, volumes calculation, sections or as a basis for virtual reality and rapid prototyping.
