Land Surveying

VRMesh delivers powerful functionalities for civil engineering design, such as, terrain design, architectural design or heritage projects. The software's advanced point cloud clean up and polygon meshing functionalities allow users to process large data sets and create accurate meshed model for use in downstream applications.

Key Features:

• Handle large data sets in excess of multiple million points

• Support vertex color during the point cloud/mesh processing

• Automatically register multiple scans

• Quickly manipulate point clouds: smooth, decimate, clip, extract

• Generate boundary curve and cross-section curves directly on point clouds

• Accurately create 3D polygonal model

>> Reduce large point clouds into manageable size for use in Autodesk® Civil 3D®
VRMesh has the ability to quickly clean up large-sized point clouds, remove extraneous points, align several scans together, and reduce overall point size.

Accurately reduce the size of a surface or overall point clouds. (Please refer to an example using VRMesh in the paper "Optimize the Performance of AutoCAD® Civil 3D®" at Autodesk University 2007.)

>> Deliver accurate and colored polygonal models for visualization
VRMesh has the ability to automatically convert very large point clouds to accurate 3D polygonal meshes with preserving color information. Surveyors can use these accurate polygonal models of scanned scenes for visualization applications, e.g., sharing polygonal models with clients and colleagues, and viewing them in NavisWorks JetStream.
