As-Built 3D Mesh Models

Point clouds obtained from a 3D laser scanner can be converted into a 3D mesh model for clients who require a digital surface model. A 3D mesh model is a digital representation of an object’s surface, composed of vertices, edges, and faces that define the object’s shape and structure in 3D space. It is created from a point cloud through a process called triangulation, which connects data points to form a mesh surface by generating a network of triangles.

The level of detail in a 3D mesh model can be adjusted based on the client’s requirements. Smaller, denser triangles provide higher resolution (resulting in a larger file size), while larger, less dense triangles offer lower resolution (resulting in a smaller file size). 3D mesh models are often used as an intermediate model to create other model types, such as 2D and 3D CAD models, or to perform processes such as machinery alignment and inspection, storage tank inspection and calibration, volume surveys, deformation and wear analysis, topographic mapping & georeferencing, and propeller inspections.

With the client’s specific needs in mind, we can also apply the real color of the scanned object to the 3D mesh model using images captured by the 3D laser scanner. This format is commonly used for VR/AR applications and for the creation of other 3D digital content, including video games and advertisements. Additionally, 3D mesh models provide a flexible option for clients who prefer to conduct their own data processing to generate various outputs, such as 2D and 3D CAD models.
