Manage Meshes

Several tools, starting from the mesh import to the mesh creation and manipulation are available.

In the next paragraphs a short overview.

Import Meshes

Reconstructor can import various type of mesh files; below all of them are listed.

Some type of mesh need specific interface to be imported, you'll see it at the import start.

Mesh creation

Reconstructor® provides 4 typologies of mesh techniques. Different number and type of point clouds can be used as a basis to create a mesh, depending on the meshing technique:

	On Grid Point Clouds	On Unstructured Point Clouds	Suggested for…
Multiresolution Mesh Fast meshing technique that give back light meshes that may have holes in some situations.	✓ (one or more)		To obtain a well defined and fast mesh from a single structured point cloud, with a good quality/computational time ratio
Mesh from predefined view Relatively slow meshing technique that gives back convex meshes without holes. It’s a view dependent, high defined mesh (each point is a vertex)	✓ (one)	✓ (one – single or clustered point cloud)	Useful for façades (using orthocamera) and tunneling (using cylindrical camera)
3D Mesh Approximate 3D meshing not view-dependent and taking as constraints the points' positions and orientations (normals)	✓ (one)	✓ (one – single or clustered point cloud)	Useful for convex surfaces.
Topographic Mesh [Only available in MINING add-on] Fast meshing algorithm designed for DTM models. It gives back a watertight, light, smoothed mesh useful for isolines and volumes calculation.	✓ (one or more)	✓ (one or more)	Useful for land survey and mining

Mesh manipulation

	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.
	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 mesh.
	Get mesh borders as polyline To create a new polyline containing the mesh's borders and add it to the project
	Mesh selection from current view point To cut a portion of a mesh using 2D video selection tools on the current view.

Reconstructor® provides many other functions for editing meshes.
