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:
|
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. |
|
This dialog allows to lump together in a single mesh an arbitrary set of triangle meshes. |
|
To create an unstructured point cloud from the vertexes of the mesh using the color attribute of the mesh. |
|
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.
