3DReshaper® meshing process is one of the most powerful on the market as it has been designed completely in 3D. Process large point clous quickly and easily to obtain light-weight, accurate and aesthetic models.

We offer different meshing strategies to give the best result depending on the quality of the original point cloud and your expectations.

Two steps are better than one

In case of noisy point clouds, the 3DReshaper approach is to work in two steps to get a perfect result:

  • In a first step, create a very rough mesh in order to have quickly the global shape
  • In a second step, refine this rough mesh with the point cloud by adding triangles where we have the details
Specific triangle reorganization

Meshing along curvatures is a 3DReshaper feature that enables to organize triangles according to local curvature. The triangle reorganization follows the "flow" of the shape so that sharp angles and small radii are better respected. This powerful technique significantly improves the quality of the 3D meshed models:

  • Greater accuracy of the shape, especially in sharp angles and small radius areas
  • Better aesthestics and smoothing of the shapes
  • Lower number of triangles needed to reach final tolerance of the model
A complete offer

Many tools are available to further improve meshes once created:

  • Smoothing to keep details and improve general aspect
  • Holes filling to treat a zone that could not be scanned or to obtain a closed model
  • Decimation in order to reduce the size of your meshes
  • Sharp Edges Reconstruction to obtain perfect edges even if they are not scanned with a very high density
  • Extrusion to create tubular shapes along a path
  • Constraint Meshing to use a polyline as a breakline in your mesh
  • And much more
Ground Extractor: a dedicated tool to create a DTM

Creating the model of a terrain is not always an easy task when dealing with scans of a whole area containing also vegetation, cars, road signs, buildings, etc. 3DReshaper brings an automatic solution to extract the ground out of a point cloud. The command "Extract ground" allows you to automatically create a mesh of a terrain directly from a global point cloud (not filtered). You just have to define the terrain maximum slope and a direction (generally Z in case of DTM) to create your DTM, extract points on the ground or points not on the ground. The extraction is completely automatic.

Building Extractor: create simplified meshes

Some applications require simplified models which are light and easy to handle, keeping the best accuracy. The "Building Extractor" feature is a very easy guided solution to extract planar surfaces in order to create the simple model of an object, a building or a whole street. Just click points on the cloud to extract planes, then all intersections and edges are computed automatically to create a complete model. Walls are also automatically constrained in order to be vertical, horizontal or along an axis.
