Mesh Offsetting
Offsetting is a mechanism whereby a solid can be expanded or contracted and is used in a variety of applications including CNC machining, collision detection, stereolithography, rapid prototyping, toolpath and model generation.
Polygonica allows 3D solids to be offset either inwards or outwards. Solids may be offset by a constant distance in all directions, which is known as a spherical offset. Additionally, anisotropic offsetting can be performed where the solid is offset by different amounts along each axis.
The offset that Polygonica performs is purely polygonal. This is achieved using Polygonica’s unique Boolean engine and means that there is no sampling involved and that every polygon in the original geometry will be offset to produce an identical, but offset, polygon in the resulting geometry.
