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

To create simple meshes
