In this post I will present three equivalent algorithms to compute the edges of a polygonal mesh. The algorithms are subsequent optimization steps to produce the exact same result with progressively increased efficiency. In the first part of this text, I will describe the typical representation of a mesh topology, distinguish between different concepts of edges. To better define the subject, picture the wireframe of a polygonal mesh. Assuming there is no overlapping geometry in the scene, if yo

Since version beta10 OrioleDB supports building indexes other than B-tree. Bridged indexes are meant to support these indexes on OrioleDB tables. OrioleDB stores its table rows inside a B-tree built on a table primary key and keeps MVCC information in an undo log, so it can’t simply plug PostgreSQL’s existing Index Access Methods (GiST, GIN, SP-GiST, BRIN, …) into that structure. While PostgreSQL's Index Access Methods: reference a 6-byte ctid (block number and offset in the heap) -- not a log

TL;DR Samsung’s upcoming Antioxidant Index feature will let you track your body’s beta carotene levels via your Galaxy Watch’s sensors. The watch must be removed and pressed against the thumb to perform the measurement, which then syncs with the Samsung Health app on the connected phone. Full compatibility details remain unclear, but you’d likely need One UI 8 Watch and a compatible Galaxy Watch, possibly the upcoming Galaxy Watch 8 series.

Tables and data grids in the web are everywhere – luckily, most are for data viewing, but sometimes, you'll end up needing edit functionality in a grid layout, like an Excel spreadsheet. Unfortunately, things immediately become a little trickier once a grid is made up of interactive elements like inputs. The tricky thing I want to talk about today in these interfaces is focus management. To illustrate, let's draw up the simplest of spreadsheets. We'll grab some inputs and arrange them in a grid

H3 indexes points and shapes into a hexagonal grid. H3 is a discrete global grid system for indexing geographies into a hexagonal grid, developed at Uber. Coordinates can be indexed to cell IDs that each represent a unique cell. Indexed data can be quickly joined across disparate datasets and aggregated at different levels of precision. H3 enables a range of algorithms and optimizations based on the grid, including nearest neighbors, shortest path, gradient smoothing, and more.
