MachineWorks Ltd, Sheffield, UK, has announced that the upgraded Polygonica 3.2 software is now available. A component library for polygon meshes, the main functions of the software include healing, Booleans, offsetting, remeshing, simplification, shrinkwrap, surface & feature detection and point-cloud manipulation & meshing.

“Much of the headline functionality in Polygonica 3.2 is based on direct requests from customers in the AM, CAE and CAM fields,” stated Dr Fenqiang Lin, Managing Director of MachineWorks. “We are really pleased with what the product team has been able to deliver during this release cycle, which continues to advance Polygonica’s technology while helping to solve some of the most challenging geometric problems our customers are facing today.”

Improvements in Polygonica 3.2 include:

  • Mesh deformation for Additive Manufacturing compensation
    • General smooth mesh morphing operations
    • Computation of accurate deformation vector fields between two meshes
    • Application can define deformation from CAE simulation or scanned part
  • Mesh-mesh registration
    • Accurately register two meshes from different coordinate spaces
    • Refine registration based on application-defined regions
    • Register scanned mesh with CAD part
  • Compute the medial axis of a solid as a set of points and corresponding radii
  • Remeshing enhancements
    • Keep exact shape of original model
    • Adapt triangle edge lengths to small features on the mesh
    • Specify vertices to preserve during remeshing
    • Specifying minimum edge lengths during curvature-sensitive remeshing
  • Extensions to offsetting to allow deeper analysis of the offset result
    • Create a new offset with faces, edges and vertices mapped from the original
    • Report significant intersection edges between the resulting offset faces that were part of different surfaces on the original solid
  • A new dilation operation has been added to offset open, self-intersecting polylines that don’t represent closed regions
