VRMesh Reverse

A complete reverse engineering workflow for users to wrap 3D scan data into accurate polygon meshes as well as NURBS surfaces. It delivers best-in-class point cloud clean-up tools and mesh processing functionalities. It also provides step-by-step guides to wireframe curve detection and NURBS creation.

Reverse engineering workflow in VRMesh

Features and Benefits

  • Automatic registration working on unstructured points

  • Advanced point cloud decimation and denoising algorithms

  • Accurate point cloud triangulation

  • Remesh smoothing with preservation of edges

  • Seamless merging of multiple surfaces

  • Comprehensive editing tools: Boolean, offset, fillet, extrude, clip, fit curbs…

  • Quads and NURBS creation

  • Texture generation from vertex colors

  • Accurate inspection and measurements


Working Examples:

>> Point Cloud to Mesh

This video shows three workflows of triangulation in VRMesh: convert points to meshes directly for a super accuracy, or decimate points before triangulation for time-saving and a good accuracy, or extract a region of interest to work on.
