Mesh creation


In this section you can first learn how to create triangle meshes. 


Reconstructor® provides many typologies of mesh creation 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 

The algorithm designed for DTM models. It gives back a watertight

Fast meshing, light, smoothed mesh useful for isolines and volumes calculation.

✓
(one or more)

✓
(one or more)

Useful for land survey and mining

Mesh point list

Two methods to transform a list of point into a mesh
