Abstract
The modern CAD/CAM workflow includes many disparate formats, often based on ob-ject boundaries (e.g. NURBS or triangles). These representations complicates digital fabrication, which requires closed volumes. Furthermore, boundary representations requires sophisticated calculations to perform even basic computation solid geometry (e.g. finding the intersection of two parts). Approach I propose to develop a full digital fabrication workflow operating on a volumetric repre-sentation of solid models. This workflow will begin with hierarchical design tools based on functional representations, which will populate a sparse voxel octree representing a solid object’s volume. Next, specialized path planning tools will calculate toolpath trajectories for a variety of machines and processes. Finally, these toolpaths will be executed on existing machines to produce solid objects. This workflow could also be extended to importing volumetric scan data and path-planning for five-axis machin-ing. Novelty
