Network Lab is an open source Windows software for processing and editing 3D triangular meshes. It provides a set of tools for editing, cleaning, healing, validating, rendering, texturing, and transforming meshes. It offers features for processing raw data obtained from 3D digitizing tools/devices and for preparing models for 3D printing.

Input/output in many formats:

• Import: PLY, STL, OFF, OBJ, 3DS, COLLADA, PTX
• Export: PLY, STL, OFF, OBJ, 3DS, COLLADA, VRML, DXF

Features and Features

alignment
The 3D data alignment step (also known as registration) is a fundamental step in the processing of 3D scan data. It provides a powerful tool for moving different grids into a common frame of reference, capable of managing a large set of range maps. MeshLab implements a finely tuned ICP mutual alignment step followed by a global packet correction error distribution step. Leveling can be performed on grids and point clouds from multiple sources, including active scanners (both near and far) and 3D-from-image tools.

Visualization and presentation
Application visualization features (including decorators and shaders) can help in graphical representation of specific characteristics of a 3D model. You can control camera perspective/orthographic view settings and use predefined canonical views. The app also offers high resolution screenshot

a feature that is extremely useful when creating graphical survey documentation.

Reconstruction
The process of transforming independent data or point clouds into a single-surface triangulated mesh can be performed using various algorithmic approaches. It provides several solutions for restoring the shape of an object, ranging from volumetric (marching cube) to implicit surfaces (shielded Poisson).

Color processing
It can manipulate vertex and face colors using a series photoshop-like filters (gamma, saturation, brightness, contrast, levels, smoothing, sharpening). Automatic filters are available to calculate Ambient Occlusion and Volumetric Obscurance and match them with vertex or face color.

Color overlay and texturing
Color information can be as important as geometry, but some data collection technologies do not provide accurate appearance data. MeshLab contains a pipeline for aligning and projecting color information (from a set of uncalibrated images) onto a 3D model. Several automatic and assistive methods are provided to achieve high quality color coding with both vertex and texture matching.

Offset, gouge, closure
In addition to being able to export to STL (one of the most common formats for 3D printing), it can be used to prepare 3D models for printing by creating inner shells, resampling/re-meshing the 3D model for easier slicing, closing small holes to get waterproof meshes and leveling the bottom for better grip on the platform.

Cleaning up 3D models
The application offers a series of automatic, semi-automatic and interactive filters to remove those geometric elements that most programs and algorithms usually consider “wrong”. You can remove topological errors, duplicate and unused vertices, small components, degenerate or intersecting faces, and many other geometric and topological features. You can then use various automatic and interactive selection methods to isolate and remove unwanted areas of your meshes and point clouds.

Model comparison
Measuring the geometric difference between two 3D models using the Hausdorff distance is a common approach in mesh processing. Many years ago (in 1997!) the Visual Computing Lab developed and freely distributed what has become the standard tool for such a task, Metro; the relevant document has been cited over a thousand times.

Scaling, positioning and orientation
3D models, especially from surveys and scans, often need to be reoriented or placed in a specific frame of reference; also, if they were generated from 3d-from-photos, they usually need to be scaled to become metric. The Mesh Lab application provides many functions to control the scale, position and orientation of the 3D model, including basic transformation operations such as move/scale/rotate, automatic re-centering and axis alignment, georeferencing with anchor points, interactive handles for rotation/translation /zoom and many more.

Convert and share 3D models
It can import and export a number of different 3D data formats and to online services such as SketchFab. Thus, the user can exchange data with other tools (including BlenderPhotoscan, VisualSfM, Cloud Compare, Autodesk Tools) running in the context of complex 3D processing pipelines in a number of different contexts and applications. Scripting features will make this type of use even easier and unattended.

Simplify, Refine, and Remesh
Typically, when processing a 3D model, you want to reduce its geometric complexity by creating geometry of the same shape, but with fewer triangles (or points). The program offers various ways to simplify (decimate) triangulated surfaces, allowing you to preserve geometric details and texture overlay or selectively reduce the number of points in a point cloud. In other cases, the user may want to increase the number of triangles (or points): it also provides various subdivision schemes, remesh and resampling filters to increase the geometric complexity of 3D models, or to optimize point distribution and triangulation quality.

Image integration
Raster layers were introduced to MeshLab to allow us to go beyond the standard 3D model. Application users can also import images and other 2D objects into the project. These bitmap layers can be used not only to project color information onto a 3D model, but also to create specific viewpoints or to store the entire 3D rendering process, including also the images used to create the final results. .

Measurement and analysis
Interactive two-point measurement of a 3D model in the app is very easy. What’s more, automatic filters will return various geometric and topological information about your 3D model (or just the selected area), and the Section tool can export mesh cuts as polylines. Various geometric information (such as curvature, geodesic distance, or local vertex density) can be calculated for meshes and 3D models using automatic filters.
