LOS ANGELES Erick Pulgar World Cup Jersey , July 18 (Xinhua) -- A new computational method, to be demonstrated at SIGGRAPH 2017 later this month in Los Angeles, California, is addressing a well-known bottleneck in computer graphics: 3D content creation.


The new generative model, GRASS, based on deep neural networks developed by an international research team, enables the automatic creation of plausible, novel 3D shapes Enzo Roco World Cup Jersey , giving graphic artists in video games, virtual reality (VR) and film the ability to more quickly and effortlessly create and explore multiple 3D shapes so as to arrive at a final product.


With GRASS, "Everything is driven implicitly by the examples, or learned from data," Kai Xu, a co-author of a new research paper, said in a press release.


According to the paper, published in ACM Transactions on Graphics Eduardo Vargas World Cup Jersey , the new method uses machine-learning techniques and artificial intelligence to eliminate the burden of generating multiple 3D shapes by hand.


Researchers believe that computational methods like GRASS could one day transform the video game, film, computer-aided design (CAD) and VR industries.


Generating new 3D shapes is challenging. "The time consuming process of 3D content creation prevents computer graphics from being as ubiquitous as we had hoped," said the associate professor of computer science at the National University of Defense Technology (NUDT), China, and soon-to-be visiting professor at Princeton University.


"Our work is a data-driven automatic shape generation computational method. Given a set of example 3D shapes, our task is to generate multiple shapes of one object class, automatically Edson Puch World Cup Jersey ," Xu said.


As an example, Xu described given a set of chairs, the new method can create more chairs but with different geometric structures, and do so quickly and simply, allowing even a novice user to utilize the method.


According to the press release on Tuesday, the core ideas that led to GRASS were born out of two questions the researchers had been asking themselves for years.


The first is whether 3D shapes can be transformed into and generated through genetic codes mimicking human DNA. Fittingly, the first code name for the project was "Shape DNA". GRASS learns to encode an arbitrarily complex 3D shape into a fixed set of parameters, and regenerate it from those parameters.


The second question is how to best represent 3D shapes for computer-aided synthesis. The team Cristopher Toselli World Cup Jersey , led by NUDT, eventually settled on a structural representation, describing a 3D shape as an organized hierarchy of its constituent parts.


The authors from NUDT, Adobe Research, IIT Bombay, Simon Fraser University and Stanford University are set to showcase their work at SIGGRAPH 2017, which is known for the spotlight it shines annually on the most innovative in computer graphics research and interactive techniques worldwide.

ROME, April 5 (Xinhua) -- Mafia in Italy has traditionally been engaged in a variety of criminal activities but over the past few years they have turned their hand to the power and wealth centers of the country.


"Mafias have silently arrived in Rome Claudio Bravo World Cup Jersey ," Giovanni Tizian, a journalist of The Espresso group and an author of books on mafia, told Xinhua.


Big investments started between the 1990s and 2000s, he said, first targeting small shops in the outskirts and then gradually moving to luxury businesses.


Recent investigations have uncovered dozens of mafia-owned restaurants, bars and shops in the capital.


Sabrina Alfonsi, an official in Rome, has sounded the alarm bell that nearly 70 percent of bars and restaurants in the city's historic center are in the hands of the organized crime.


The worrying map of criminal infiltrations has shown that mafia has not only in search of territorial control but especially of "vehicles for power and wealth Charles Aranguiz World Cup Jersey , ways to get in touch with influential persons," Tizian noted.


The service industry, real estate and trade are currently among the legitimate sectors where mafia has invested their profits, often covered up by unlawful transactions and political connections, from Rome to Milan, where investigators said that 'Ndrangheta - regarded as the richest of Italy's mafia - has become "monopolistic."


In one of latest major operations conducted last month, police across Italy have seized tourist resorts and luxury cars worth around 420 million euros (575 million U.S. dollars) from 'Ndrangheta, which recent studies estimated has a turnover equal to more than 3 percent of the country's gross domestic product.


According to Libera Arturo Vidal World Cup Jersey , a renown antimafia association, thousands of businesses in Italy's largest cities are owned by mafia. At the end of 2012, the number of hotels and restaurants seized from mafia amounted to 173, or around 10 percent of Italy's food service companies.


"There is no investigation where the name of a restaurant, bar or noted gathering place is missing. For mafias, making dirty money clean inside legal and institutionalized washing machines has become a primary target," Libera's responsible in Rome Marco Genovese explained to Xinhua.


"Everything is being done in the open," Genovese pointed out. He said mafia is especially cashing in on the current economic slowdown and are often acting as "banks" for the many small- and medium-sized enterprises that were the main victims of rackets and loan sharking.


In Italy Alexis Sanchez World Cup Jersey , there are several town councils being dissolved every year for mafia infiltrations, and reports of politicians from the entire political landscape arrested on charges of links with the organized crime are frequent events.


Earlier this week, police detained an undersecretary in the economy ministry from 2008-2010, Nicola Cosentino, accusing him of colluding with the mafia.


Some steps have been made to forge greater consciousness and improve legislation, Tizian went on to say.
