We introduce a reliable method to generate offset meshes from input triangle meshes or
triangle soups. Our method proceeds in two steps. The first step performs a Dual Contouring …

Surface offsetting is a crucial operation in digital geometry processing and computer-aided
design, where an offset is defined as an iso-value surface of the distance field. A challenge …

We present an efficient, trivially parallelizable algorithm to compute offset surfaces of shapes
discretized using a dexel data structure. Our algorithm is based on a two-stage sweeping …

Performing dilation and erosion using large structuring elements can be computationally
slow–a problem especially pronounced when processing volumetric data. To reduce the …

We describe an approach for performing constant radius offsetting and the related
operations of filleting, rounding and smoothing for implicit surfaces. The offsetting operation …
