New Point-Cloud and Hole Filling Functionality Polygonica's Latest Release Showcased at TCT

SHEFFIELD – 24th Sep 2018 – MachineWorks Ltd will be exhibiting at the TCT Show in Birmingham on stand R36 from the 25th to the 27th of Septembershowcasing the new Polygonica software release v2.2.

The 2.2 release of the Polygonica mesh modelling software toolkit includes significant upgrades to the point cloud to mesh processing pipeline. CAD, CAM and CAE vendors can now easily integrate advanced point cloud import functionality directly into their existing software systems allowing direct support for scan-based workflows without the requirement for external software.

As well as general performance improvements, memory usage has been reduced to support the processing of larger point clouds.

The new surface-fitting method initially builds a surface-based structure from the point cloud and the mesh is then generated from that. This technique delivers much smoother mesh surfaces for noisy point data that are more suitable as a starting point for reverse engineering.

Polygonica’s hole-filling algorithms have also been upgraded. Annular hole-filling automatically recognises islands and attaches them to the correct hole. Ruled-surface filling joins a hole with a single island using a ruled surface. This can also be used to bind disjoint sheets.

The features method respects features across a hole in one direction whilst the features smooth method recognises features in all directions and creates a smooth surface that respects the curvature at the hole’s edges.

Polygonica’s new automatic hole filling allows multiple holes to be filled in at once which can greatly improve the performance for large meshes. Hole boundaries can be automatically smoothed during post-processing.

new offsetting method has been added that allows simultaneous inwards and outwards offsetting in one function call. Open surfaces can now be extended to allow for improved trimming.

The adaptive-simplification algorithms in Polygonica are now multi-threaded meaning large meshes from laser scans can be decimated in seconds whilst maintaining tolerance.

A new shrink-wrapping function has been added that closes very poor quality meshes and triangle soups whilst removing internals from CAD assemblies to reduce data for faster visualisation in VR/AR and mixed-reality scenarios.

Polygonica component technology offers OEMs focused on leveraging the benefits of new Additive Manufacturing processes a speedy access-to-market and years of specialised software development at their fingertips.

About Polygonica

Polygonica is a solid modelling software toolkit for processing polygon meshes. Built on MachineWorks' core engines, Polygonica's unique polygonal modelling technology takes advantage of 23 years of development providing automatic, fast and robust Boolean operations. Other algorithms in Polygonica allow solid healing, simplification, slicing, sectioning and spun profile calculation.

Polygonica has a wide range of applications such as CFD/FEA meshing, CAD/CAM/CAE, additive manufacturing where there is a requirement to repair defective models with vast numbers of polygons, rapid prototyping, reverse engineering, 3D movies and gaming, geo-exploring, urban modelling and other 3D digital applications.
