3D Gaussian Splatting achieves real-time novel view synthesis by representing scenes as millions of alpha-blended ellipsoids. Making this representation semantically meaningful turns out to be surprisingly hard. This post surveys the core technical challenge, the alpha-blending problem, and the three paradigms that have emerged to address it across the CVPR, ECCV, and ICCV 2024–25 literature.

An in-depth exploration of spatial interaction models, covering their theoretical foundations, mathematical formulation, and practical applications in urban planning. This article includes interactive visualizations to build intuition about how these models predict human mobility patterns in cities.

Networks that are constrained by some geometry and are embedded in two-or three dimensional space can be thought of as spatial networks. The constraints that space imposes can have important effects on their topological properties and in the processes which take place on them. Here we explore centrality measures of the metro systems of London, New York, Chicago, and Santiago de Chile. The time-weighted graphs were constructed using publicly available GTFS data and visualized using javascript.
