Mesh manipulation


In this section you can first learn how to edit triangle meshes to select and to filter them and so to obtain a better result from your data.


Reconstructor®  offers several functions for editing meshes:


Mesh Editor

An editing environment to perform advanced operations such as hole-filling, borders detection, editing triangles and vertexes, smoothing surfaces, decimating, crests and toes extraction.

Mesh selection from current view point

To cut a portion of a mesh using 2D video selection tools on the current view.

Mesh selection  with 3D polyline

To cut a portion of a mesh using an input mesh, a 3D polyline and a viewpoint.

Merge meshes into one

This dialog allows to lump together in a single mesh an arbitrary set of triangle meshes.

Convert mesh to point cloud

To create an unstructured point cloud from the vertexes of the mesh using the color attribute of the mesh.

Get mesh borders as polyline

To create a new polyline containing the mesh's borders and add it to the project.


From the item's context menu other commands are available:


  • Compute mesh normals

To compute or update the triangles' normals for the mesh.

  • Invert winding

This command inverts the ordering of the vertexes for each triangle, so the surface is flipped to the opposite side and also the normals are inverted.

  • Compute area

This command returns the mesh area as sum of the areas of all the mesh's triangles.

  • Compute volume from Z=0 plane

This command returns the volume resulting from integrating the mesh on the XY plane of the current UCS. Mesh triangles below the XY plane will result in zero volume.
