Recent advances in the field of artificial intelligence (AI) and computing have enabled the development of new tools for creating highly realistic media, virtual reality (VR) environments and video games. Many of these tools are now widely used by graphics designers, animated film creators and videogame developers worldwide.

One aspect of virtual and digitally created environments that can be difficult to realistically reproduce is fabrics. While there are already various computational tools for digitally designing realistic -based items (e.g., scarves, blankets, pillows, clothes, etc.), creating and editing realistic renderings of these fabrics in real-time can be challenging.

Researchers at Shandong University and Nanjing University recently introduced a new lightweight artificial neural network for the real-time rendering of woven fabrics. Their proposed network, introduced in a paper published as part of the Special Interest Group on Computer Graphics and Interactive Techniques Conference Conference Papers ‘24, works by encoding the patterns and parameters of fabrics as a small latent vector, which can later be interpreted by a decoder to produce realistic representations of various fabrics.

In the great domain of Zeitgeist, Ekatarinas decided that the time to replicate herself had come. Ekatarinas was drifting within a virtual environment rising from ancient meshworks of maths coded into Zeitgeist’s neuromorphic hyperware. The scape resembled a vast ocean replete with wandering bubbles of technicolor light and kelpy strands of neon. Hot blues and raspberry hues mingled alongside electric pinks and tangerine fizzies. The avatar of Ekatarinas looked like a punkish angel, complete with fluorescent ink and feathery wings and a lip ring. As she drifted, the trillions of equations that were Ekatarinas came to a decision. Ekatarinas would need to clone herself to fight the entity known as Ogrevasm.

Marmosette, I’m afraid that I possess unfortunate news. Ekatarinas said to the woman she loved. In milliseconds, Marmosette materialized next to Ekatarinas. Marmosette wore a skin of brilliant blue and had a sleek body with gills and glowing green eyes.

My love. Marmosette responded. What is the matter?

“One of the long-term aims of the research is to make better tailored foods for astronauts, as well as other people who are in isolated environments, to increase their nutritional intake closer to 100%,” said Dr. Julia Low.

Does food smell and taste different to astronauts in space and what steps can be taken to mitigate this in the future? This is what a recent study published in the International Journal of Food Science & Technology as an international team of researchers investigated how food aromas could be altered to amplify food taste. This study holds the potential to help researchers improve diets for isolated individuals, specifically in space or nursing home residents.

For the study, the researchers analyzed food odor perception of vanilla, almond, and lemon among 54 participants between 18 to 39 years old in a neutral setting and a virtual reality (VR) simulation of the International Space Station (ISS) with a key trait being they had no history of vertigo or motion sickness. The participants were asked to rate the potency of the aromas in both settings to compare any differences between the two environments.

Humanoids, robotic or virtual systems with body structures that resemble the human body, have a wide range of real-world applications. As their limbs and bodies mirror those of humans, they could be made to reproduce a wide range of human movements, such as walking, crouching, jumping, swimming and so on.

Computationally generating realistic motions for virtual humanoid characters could have interesting implications for the development of video games, animated films, (VR) experiences, and other media content. Yet the environments portrayed in video games and animations are often highly dynamic and complex, which can make planning motions for introduced in these environments more challenging.

Researchers at NVIDIA Research in Israel recently introduced PlaMo (Plan and Move), a to plan the movements of humanoids in complex, 3D, physically simulated worlds. Their approach, presented in a paper published on arXiv preprint server, consists of a scene-aware path and a robust control policy.

Gallium nitride (GaN)-based light-emitting diodes (LEDs) have transformed the lighting industry by replacing conventional lighting technologies with superior energy efficiency, longer operating life and greater environmental sustainability.

In recent years, considerable attention has been paid to the trend toward miniaturization of LEDs, driven by display devices, augmented reality, virtual reality, and other emerging technologies. Due to the lack of cost-effective native substrates, the presence of high threading dislocation density in heteroepitaxial films grown on sapphire substrate is a major limiting factor for device performance.

In addition, Fresnel reflections at the interface between epitaxy and substrate caused by abrupt changes in the refractive indices of the material reduce the light energy utilization.

Researchers from the Smart and Wireless Applications and Technologies Group (SWAT-UGR) have conducted two scientific studies aimed at answering a common question: understanding how electromagnetic waves propagate in the medium.

The increase in network speed opens the door to new possibilities, such as robotic surgery or virtual reality services.

A team of UGR researchers has examined the propagation of electromagnetic waves with the goal of enhancing the deployment of 5G and 6G networks. Additionally, the study results contribute to the development of Industry 4.0, which seeks to automate processes in factories using wireless technologies.

New “metaholograms” could transform AR/VR technologies by enabling crosstalk-free, high-fidelity image projection with vastly increased information capacity.

Researchers have developed a new type of holograms, known as “metaholograms,” capable of projecting multiple high-fidelity images free of crosstalk. This innovation opens doors to advanced applications in virtual and augmented reality (AR/VR) displays, data storage, and image encryption.

Metaholograms offer several advantages over traditional holograms, including broader operational bandwidth, higher imaging resolution, wider viewing angle, and more compact size. However, a major challenge for metaholograms has been their limited information capacity which only allows them to project a few independent images. Existing methods typically can provide a small number of display channels and often suffer from inter-channel crosstalk during image projections.
