James has been writing about technology for years but has loved it since the early 90s. While his main areas of expertise are maker tools -- 3D printers, vinyl cutters, paper printers, and laser ...

Each line segment of a distance-time graph represents one part of a journey. A distance-time graph, sometimes referred to as a travel graph, is a way of representing a journey. It is helpful to have ...

A 3D shape with all straight edges and flat faces is a polyhedron. Other 3D shapes with least one curved surface are not polyhedra. A 3D shape with regular polygonal faces, meeting at equal angles, is ...

Abstract: We prove that the class of 3D-grids cannot be transduced from planar graphs, and more generally, from any class of graphs of bounded genus. To prove our result, we introduce a new structural ...

Abstract: Controllability plays a crucial role in the practical applications of 3D indoor scene synthesis. Existing works either allow rough language-based control, that is convenient but lacks ...

This repository contains the official PyTorch implementation of the work "Equiformer: Equivariant Graph Attention Transformer for 3D Atomistic Graphs" (ICLR 2023 Spotlight). The QM9 dataset will be ...

This repository contains the official code for our MICCAI 2025 paper, “Semantically Consistent Discrete Diffusion for 3D Biological Graph Generation.” We introduce a discrete diffusion framework that ...
