🌟Gaussian Splatting for Large-Scale Terrain: Updates, Challenges, Issues, and Insights! ~4k video available at https://lnkd.in/gHrcpRui 🎉Updates: + Enhanced sharpness in edges and textures, particularly on buildings. + Significant reduction in floating artifacts and noise. + Exceptionally realistic rendering when viewed near the camera trajectory. 🔍Issues: - Vegetation appears blurred. - Noticeable drop in quality when rendered at a distance from the camera trajectory. 🚧Challenges: - The Gaussian Splatting (GS) model lacks compactness, leading to potential GPU memory overruns in large-scale terrains. - Acquiring high-quality data for background elements (sky and terrain outside the area of interest) remains challenging. - Camera pose estimation still depends on the Structure from Motion (SfM), and the GS model's quality is intrinsically linked to the accuracy of this estimation. 💡Insight: + Many demo videos showcase the impressive quality of GS by rendering on the camera trajectory, often masking the artifacts encountered when rendering off this path. This video aims to present a realistic view of what our Gaussian Splatting pipeline can achieve (without any manual editing) for large-scale terrain, particularly from ground-level perspectives. 🔗Stay Connected: 👉 Connect with me (Meida Chen) for more insights and updates. 👉 Subscribe to my YouTube channel (https://lnkd.in/g8KRhWYa) to dive into my latest research on Large-Scale Gaussian Splatting! #gaussiansplatting #3dmodeling #drone #technology #innovation #realestate #architecture #construction

Stable design? When do we say something is stable? We had developed a light and stable flying wing for the competition. The biggest thing we were happy about was the stability plane achieved as it was moving through the free flowing fluid. It had a remarkably smooth lateral stability and a perfect balance in point of resultant lift to the point of resultant gravitational pull. Since the system didn't have gyroscopic stability embedded, the manual control in combination with the right proportion of forces had its unique beauty. But which all factors are responsible for a very specific design of stability? Our work speaks for itself inline with the experience. The answer is probably a combination of a few : - Planned weight distribution throughout body, which which would lead to a specific torques and their rotational innertias about the three axes additionally sets a specific Centre of gravity. - A defined structure for internal mass to stay and not change position and hence related forces in the payload bay. - A well thought structure for smooth flow of fluid around the body. Which could have a balance on variable resultant resultant lift positions to the almost constant resultant gravitational pull point. - A dedicated team of curiously passionate people who wants to bring out best and set a delta of change towards betterment. - Research on the change that needs to be done compared to previous designs.

Bonus use: Help out on a lunar mission: One of the more impressive uses of duct tape came in 1970, during the famous Apollo 13 lunar mission that went awry. During the mission, two oxygen tanks exploded. The explosion forced the astronauts to move into the spacecraft's lunar module, where carbon dioxide levels rose precipitously. The crew used duct tape (among other items) to patch together a CO2 filtering system featuring an incompatible round hole and square filter.

A reminder about the importance of mechanics of materials and good mechanical design. Could be an interesting case study for class. https://lnkd.in/eTjjngcM

Points and Vectors. On the surface, the difference between a point and a vector are easy to understand. A point represents a location in space, for example, [1. 1]. A vector represents a direction and magnitude. A simple example can be, pointA = [1, 1] plus vectorA = [2, 2], equals a new point in space: [3, 3]. What I just learned, was that a point in space can also be transformed to a direction vector. For example, the point [1, 1] could also be seen as the direction from the origin. Or, if you flip it, the vector [-1, -1] is the direction from the point, [1, 1], to the origin, [0, 0]. These things can be useful when calculating the dot product of vectors. For example, if you place a light source anywhere in your scene, that position can be used to calculate a direction to the origin. Or any other point. Have a look at a little example I tried to make below. Let me know if it's useful :) #vectors #metalkit #swift #graphics #dotproduct

✨ Throwback Thursday! 🗓📸 When it comes to Direct Field Acoustic Testing (DFAT), there aren’t many earth-shattering revelations. Instead, we’ve been perfecting the art and science of #DFAT since we pioneered it back in the '90s. This snapshot is taken from some of our first systems way back in 2010, a time when #DFAT was considered "cool" and "new." 😉 Our customers appreciate our modular speaker designs because they can customize their test setups to meet specific technical specifications and requirements. Each test is unique; no two acoustic experiments are exactly the same! So, how can a single acoustic test system meet all the possible combinations of unique requirements? It cannot. We call that adaptability "personalization." It’s like getting a perfectly tailored Italian suit. Off-the-rack suits might suffice, but they lack that perfect fit. And "one-size-fits-all" solutions? They often fall short too. Our low-frequency cabinets are intentionally separate from our mid-high and ultra-high frequency cabinets, by design. While we could, in theory, combine everything into a single cabinet unit, we’ve so far found that separating them allows us to better tailor the setup to meet the unique needs of our customers. It’s not flashy or new—it’s simply what works! With over 200 successful qualifications and counting, our results speak for themselves. 🚀🚀🚀 . . . #AcousticTesting #DFAT #AcousticQualificationTesting #RocketLaunch #Payload #Spacecraft #Satellite #SkunkWorks #ExperimentalTesting #Experiments #Science #Acoustics #Vibration #TestEngineering #NVH #Vibroacoustics #DirectFieldAcousticTest #Space #SpaceIndustry #MechnicalEngineering #AerospaceEngineering #AcousticEngineering #AudioEngineering #AdAstra #ToTheMoon #Moonshot

New design of connecting rod for 3 DOF

Wing-in-ground effect (WIG) craft is a very unique transport vehicle type with a very rich and controversial development history. Its potentially groundbreaking aerodynamic benefits with excessively complicated operational requirements and constraints made it both fascinating and highly limited solution for marine and arctic transportation. Although sophisticated research focused on the phenomenon of the ground effect and its problems, the conceptual design of WIG craft has not been explicitly formalized due to the unconventional nature of such craft and specific features that make them different from airplanes. The latest publication in the Ocean Engineering journal entitled "Constraint analysis methodology for ground-effect vehicle conceptual design" by Stanislav Karpuk at IFL - Institute of Aircraft Design & Lightweight Structures introduces a constraint analysis methodology regularly used in aircraft conceptual design to common types of WIG craft to enable a more robust design space exploration accounting for unique features of WIG craft that are not used in airplanes and improve early conceptual design activities.

The processes required to fabricate large glass domes are similar to techniques used for fabricating large telescope optics, but more complex.
