Polygonica reference app for medical implants

Polygonica is an ideal toolkit for developing surgical planning and orthotic design applications.

MachineWorks Ltd. is pleased to announce the availability of a new unsupported reference example for medical implant design, including orthognathic and craniomaxillofacial surgery planning. The source code for the app is available on an unsupported basis to existing Polygonica licensees and evaluators.

Polygonica is a component software library for working with polygon meshes that helps companies in a range of industrial markets solve complex 2D and 3D geometrical problems.

The reference app demonstrates using a range of Polygonica functions including mesh Booleans, sheet thickening, edge blending, and 3D curve operations such as UV wrapping, imprinting, smoothing, and offsetting. 
The demonstrations also show how Polygonica's shrink-wrapping can be used to create a nearly convex surface across large gaps in order to ensure the implants that are generated from the mesh surface are smooth and don't contain unnecessary bends or concavities.

In the craniomaxillofacial workflow Polygonica's mesh registration is used to closely align a mirrored model of the skull with the original, to create a similar smooth surface on which to generate the skull cap implant geometry.
