NVIDIA SMP Assist API for VR Programming

April 25, 2018

The NVIDIA SMP (simultaneous multi-projection) Assist NVAPI driver extension is a simple method for integrating Multi-Res Shading and Lens-Matched Shading into a VR application. It encapsulates a notable amount of state setup and API calls into a simplified API, thereby substantially reducing the complexity of integrating NVIDIA VRWorks into an application. Specifically, the SMP Assist driver handles creating and managing fast geometry shaders, viewport state, and scissor state in lieu of managing these states manually in the application.In VR headsets, users typically view the display through lenses which introduce a pincushion distortion. VR Applications render a barrel distorted image to reverse the pincushion distortion of the lens itself, resulting in a geometrically correct scene in the headset. The peripheral areas of a barrel distorted image are shrunk significantly. The NVIDIA VRWorks SDK includes features such as Multi-Resolution Shading and Lens Matched Shading, which allow application developers to take advantage of the non linearity in a barrel distorted image and reduce the pixel shading workload required to render a frame while maintaining visual quality.

Hi-Res audio: It’s all about a maturing market

Article | May 21, 2021

Music streaming contrasts sharply with video streaming. While the video marketplace is characterised by unique catalogues, a variety of pricing and diverse value propositions music streaming services are all at their core fundamentally the same product. When the market was in its hyper-growth phase and there were enough new users to go around, it did not matter too much that the streaming services only had branding, curation and interface to differentiate themselves from each other. Now that we are approaching a slowdown in the high-revenue developed markets, more is needed. Which is where Hi-Res comes in.

The rise of the introverted salesperson

Article | May 25, 2021

The shift to virtual selling has upended the status quo for many sales teams across the country and around the world. I firmly believe, as I’ve said before, thatnearly everything can be sold over video— and in many ways the virtual sales process makes it easier for sales reps to connect with customers and build trust.Still, there has been a great deal of resistance, and some organizations have just tried to wait it out, hoping that once COVID passed, they could go back to normal.

Six Things Blockchain Can Do For Gaming

Article | April 14, 2020

Since their foundation in the 1970s and 80s, video games have moved from fringe interest to a major media staple. The industry has enjoyed huge revenues from dedicated fans, especially over the past few months, and the growth shows no sign of slowing down. Gaming is also an industry renowned for its commitment to innovation, adopting technological developments and spawning a fair few of its own. Chief amongst technological developments over the last decade has been blockchain technology, the new system of trading and ownership built on transparency and decentralization, the standard-bearer of which is the digital currency.

Ongoing transitions in gaming industry

Article | January 19, 2021

The gaming industry is continuously evolving with current transitions derived from VR/AR, blockchain, 5G and cloud computing. The aim of this transition is to fulfill requirements of gamers such as reducing the cost of gaming, developing more immersive experience, converting tools bought in games as transferable assets, enabling gamers to play graphic intensive games on low cost devices. Currently popular games are on the go to create augmented reality versions to be played on AR headsets with their mobile phones. The google stadia platform(a platform where graphic intensive games run in data centers and gamers can play them via web browsers) has also enabled the gaming industry to eliminate the computing limitations imposed by running games in mobile devices. The only barrier in coupling both technologies to have the best of both worlds is low bandwidth of 4G which will soon be expanded when 5G rolls out in the market. TRANSITIONS IN GAMING INDUSTRY The real time game play is currently not possible for games running in data centers and being rendered on web browsers of a gamer’s device as there is latency in reflecting the character’s action on the press of a button. Such a transition will eliminate the need for highly expensive gaming consoles which has been curbing the growth rate of the gaming industry. One more concern from gamers that’s being a barrier in revenue generation for the gaming industry is that the weapons, power packs, kits and tool kits bought in any game are simply virtual and become useless when they are done with the game. The idea to buy such time bound utility becomes insensible for players. So, now the gaming industry is evaluating the option to register these buyouts in games on blockchain which can later be used as a non tangible asset by players to trade easily. The gaming theory that’s getting popularised these days will eventually leverage the AR and VR technology to transform the education industry. The idea to provide customers with user manuals running in augmented reality that can enable a non trained worker to operate the machine is also booming. Solidworks by 3Dplm is one such tool that’s heading in this direction. The transitions mentioned above are quite exciting and the way gaming industry and mentioned technologies are evolving we can expect to get our hands on such exciting gaming technology soon too at a fraction of current costs.
