How 2D grid-based algorithms can be brought into the 3D worldCloseup of the triangular 50-neighborhood. (Image by author)In my previous two articles, A Short and Direct Walk with Pascal’s Triangle and A Quick and Clear Look at Grid-Based Visibility, we saw how easy it is to generate decent-looking travel paths and compute visible regions using grid-based algorithms. The techniques I shared in those posts can be used for video games, mobile robotics, and architectural design, though our examples were limited to two…

Clarke compared the noise emissions from low altitude aircraft to that of cars in three case studies using three types of electric vertical take-off and landing vehicles, or EVTOLs, that are popular with aircraft design companies: stopped-rotor aircraft, tilt-rotor aircraft, and a hexacopter.

Credit: Pixabay/CC0 Public Domain Over the past quarter-century, the idea has taken hold among politicians across the spectrum that one of the best ways to address inequality is to give local communities the resources to do the work themselves. Provide them with funding, and they can spend it on the projects that their communities really need. But our research has shown that while many of these projects can be very positive,…

Tesla has been partnering with major new home builders all over the US to deploy solar and Powerwalls, and it now claims to have deployed “over 600 solar neighborhoods”. Tesla neighborhood is a term that is being used for new developments where all the homes integrate all or part of Tesla’s power ecosystem, including the Powerwall home battery pack. The best example is a new giant development project in Austin, Texas, by Brookfield Asset Management and Dacra where up to 12,000 new homes are…

Detailed maps of the cells in human organs show how the placenta commandeers the maternal blood supply, how kidney cells transition from healthy to diseased states and how cells in the intestine organize themselves into distinct neighbourhoods. These atlases, published on 19 July in Nature, are examples of a powerful and increasingly popular approach to studying the organs of the body in both health and disease. Each comprises hundreds of thousands of data points about gene activity and protein production in individual…

Using old insurance fire maps, researchers have enabled a machine-learning system to recreate 3D models of neighborhoods that no longer exist. Not only could the technique lead to VR tours of the 'hoods, but it could help study the economic impact of urbanization.In 1866, a young surveyor named D. A. Sandborn was contracted by the Aetna insurance company to create insurance maps for several cities in Tennessee. That project, along with an atlas he made of the city of Boston, led Sandborn to found a company that still…

Though June's Behind The Sims stream might have been focused on the The Sims 4's upcoming Horse Ranch expansion, the team surprised fans with a short segment dedicated to the next entry in The Sims franchise, Project Rene. Revealed late last year, Project Rene is EA's attempt at "renewing" of The Sims franchise and marks the series' fifth mainline entry, leading many fans to simply call it The Sims 5.Whereas the game's initial reveal focused on highlighting concepts the team was looking to integrate into…

DOI: 10.1088/1748-9326/acd654 Even after suffering flood damage, homeowners in mostly white communities prefer to accept higher risk of disaster repeating itself than relocate to areas with more racial diversity and less flood risk, according to new research from Rice University.…

A new study from the University of Kansas shows that neighborhood characteristics such as those in which renters are predominantly people of color or families with children have higher eviction rates than even gentrified neighborhoods or those with high rents.…

Toxic chemicals linked to cancer and heart disease are disproportionately polluting water sources in Black and Hispanic neighborhoods in the US, a new study shows, providing new evidence of environmental impacts targeting communities of color.Per- and polyfluoroalkyl substances (PFAS), also known as “forever chemicals” for their extreme persistence in the environment, are toxic byproducts of heat-resistant materials. They’re widely used in aerospace, construction, automotive, and electronics industries. Because of their…
