Google scommette ancora su Cardboard ed estende il supporto WebVR

Google scommette ancora su Cardboard ed estende il supporto WebVR

Google rende più semplice accedere alle esperienze di realtà virtuale con WebVR e Chrome, anche ai possessori del “visore in cartonato” Cardboard.

Lo scorso febbraio Google ha aggiunto in Chrome il supporto WebVR, standard aperto che abilita esperienze di realtà virtuale senza la necessità di scaricare e installare alcuna applicazione.
Fino ad oggi, però, WebVR risultava utilizzabile solamente sugli smartphone Daydream-compatibili (vedere anche Realtà virtuale Google, presentato l’SDK per Daydream) utilizzando il visore Daydream View di Google.

Google scommette ancora su Cardboard ed estende il supporto WebVR

Adesso WebVR si apre agli altri visori: su Android basta infatti toccare un link per avviare app per la realtà virtuale e interagirvi anche con Cardboard (Google, divisione per la realtà virtuale e “X”).
Se si fosse in possesso del “visore in cartonato” Cardboard, si possono provare gli “esperimenti” in questa pagina.
Altre dimostrazioni, fruibili anche se non si fosse in possesso di un visore Cardboard, sono pubblicate a questo indirizzo.

Dell’s Ultrasharp 30-inch 4K OLED Now On Sale: UP3017Q for $3500

One of the biggest bits of news to come out of CES 2016, over a year ago, was Dell announcing a new beacon in OLED monitors: a 3840×2160 panel measuring 30-inch diagonal using an OLED display was set to come to market. When we reported on it back at CES, they stated a $ 4999 price point for March 31st. What happened over the next 12 months was interesting: some journalists doing ‘hands-on’ reviews at tech shows, but nothing coming to retail, followed by plenty of CES 2017 news that the display had been shelved due to image quality issues. Well roll around another quarter, and it seems that Dell is ready to sell it, and shipping for this $ 3499 beast is only 1-2 weeks away.

The Dell UltraSharp UP3017Q is a 30-inch display with a 3840×2160 resolution, response time of 0.1ms, and is set to run at 60 Hz (not 120 Hz as some outlets originally reported). The monitor can reproduce 1.07 billion colors (in this case we assume 10-bit), it covers 100% of Adobe RGB color space as well as and 97.8% of DCI-P3 color space (used for digital movie projection by the U.S. movie industry and is expected to be adopted in televisions and in home cinema), and 85.8% of Rec2020. The manufacturer declares a 1,000,000:1 dynamic contrast ratio, due to the characteristic black of OLED displays.

The UltraSharp UP3017Q is a thin monitor with narrow bezels, but not remarkably thin like OLED TVs, due to the internal power supply unit as well as complex logic inside. The monitor features a mini DisplayPort (mDP) 1.2 connector, an HDMI 2.0 port, and a USB type-C port which can be used for video and data connectivity, as well as power delivery up to 100W.

The Emissive electroluminescent layer in an organic light-emitting diode is made of an organic compound that emits light in response to an electric current. The organic semiconductor layer is situated between two electrodes and does not require a backlight. As a result, it can display deep black levels unlike LCD panels which also use various kinds of backlighting. Curved TVs and monitors are also possible, since the emissive electroluminescent layer is very thin and can take different shapes.

While OLED technology can deliver deep blacks, high contrast ratio and exceptional colors, it is not free of drawbacks. Colors can shift over time, and the organic layer may degrade over prolonged amount of time. To keep the lifespan of the OLED panel maximized inside the UltraSharp UP3017Q, Dell originally advertised a special integrated presence detector into the front panel of the display, which switches the monitor off when nobody uses it, though it is not clear if this is still present. Another disadvantage of OLEDs is a possibility of static image burn-in. The UP3017Q has a special pixel-shifting technology to try and inhibit this.

The Dell UltraSharp 30 OLED monitor will cost $ 3499 and is available to order in the United States. The display at this point is only aimed at professionals that work in color-critical environments such as graphic arts and photography. However, due to the colors, contrast, and ultra-fast response time, the UltraSharp UP3017Q will be a dream display for gamers, prosumers and other users thatvalue quality.

OLED panels are considerably more expensive to produce than modern LCD panels, partly because of lower yields. In 2015, an executive from LG Electronics said that yields of OLED panels had reached 80% and would continue to grow. At the International CES 2016, Kwon Bong-suk, the head of LG’s TV business, said that the company had cut prices of OLED TVs in the U.S. by 45% late in 2015. As a result, LG expected sales of OLED televisions to triple in 2016. Price reduction of OLED TVs indicates that production costs of organic light-emitting diode panels are going down. Perhaps, over time, the Dell UltraSharp UP3017Q will also become more affordable, or Dell will release an OLED display for a wider audience.

AMD releases Radeon Software 17.4.2 driver

Support for Windows 10 Creators Update

AMD has released its latest Radeon Software Crimson ReLive 17.4.2 driver, which adds official support for Microsoft’s latest Windows 10 Creators Update as well as fixing some bugs.

According to the rather short release notes, the Radeon Software Crimson ReLive 17.4.2 driver adds initial support for Windows 10 Creators Update.

It also fixes some problems like the bug with Steam VR Asynchronous Reprojection feature, poor scaling in multi-GPU on DirectX 11 in Battlefield 1, flickering issues with Radeon ReLive on an extended display connected on Windows 7 system configurations, difficulties  with application profiles in Radeon Settings and a Windows Security popup bug on some Hybrid Graphics system configurations.

There are still plenty of known problems that hopefully will be fixed with the next Radeon Software release.

As always, the Radeon Software Crimson ReLive 17.4.2 driver supports all Radeon series graphics cards since HD 7700/HD 7900 days and is available for Windows 10 and Windows 7 in both 32-bit and 64-bit versions as well as Windows 8.1 in 64-bit version.

You can check out the full release notes as well as find the appropriate download link over at AMD’s support page.

Overwatch: online l’evento Rivolta

Blizzard ha reso disponibile l’evento Rivolta di Overwatch, che rimarrà accessibile da oggi fino al 1° di maggio. I nuovi contenuti permettono ai giocatori di rivivere il passato di alcuni eroi, sperimentando in prima persona uno dei momenti cruciali nell’universo di riferimento.

“Torna indietro nel tempo di 7 anni per fermare la rivolta sulle strade di King’s Row. Un gruppo di Omnic separatisti chiamato Settore Zero ha invaso la zona, e il tuo compito è sconfiggere i robot per liberare la città. Raduna i tuoi amici e unisciti a Tracer, Torbjörn, Reinhardt e Mercy in questa nuova rissa cooperativa. È la prima missione di Tracer, e il futuro dipende da te”, si legge nella descrizione ufficiale.

Nome immagine

“Per sconfiggere questa nuova minaccia dovrete lavorare come una squadra, sviluppando nuove strategie e adattandovi alle minacce rappresentate da un nemico apparentemente inarrestabile. I robot del Settore Zero non si fermeranno davanti a nulla, quindi voi e i vostri amici agenti dovrete essere preparati a ogni evenienza”.

Tutti i Forzieri di gioco sono stati sostituiti con Forzieri Rivolta e gli oggetti, una volta sbloccati, saranno a disposizione degli utenti senza limiti di tempo. Come è accaduto nei precedenti eventi, i Forzieri conterranno almeno un modello, highlight, emote, spray o icona della collezione Overwatch: Rivolta. Il materiale sbloccato è casuale, ma sfruttando i crediti di gioco si possono ottenere diverse personalizzazioni per tutta la durata dell’iniziativa.

Di seguito vi riportiamo il trailer narrativo e un diario degli sviluppatori, nel quale il game director Jeff Kaplan aggiorna la community sulle ultime novità proposte.
