The main clue to what foveated rendering is, comes from its name. The\u00a0<em>fovea\u00a0<\/em>is the central part of the retina. The retina is the part of your eye\u2019s anatomy that converts light to nerve signals, processed by the brain into the images you see.<\/p>\n<p>Only the fovea offers a sharp and detailed vision. The fovea only accounts for between one and two percent of your visual field, so how is it possible that we perceive our visual field with so much clarity? The answer is that our eyes are constantly moving in a scanning pattern known as a \u201c<a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK10991\/\">saccade<\/a>.\u201d By scanning the sharp sliver of our vision over the environment, our brains stitch together a high-resolution picture. You, of course, aren\u2019t consciously aware of this process.<\/p>\n<figure style=\"width: 500px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-752384 size-full\" src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2021\/08\/shutterstock_1949570272.png?trim=1,1&amp;bg-color=000&amp;pad=1,1\" alt=\"A diagram of the anatomy of the human eye showing the fovea.\" width=\"500\" height=\"500\" data-crediturl=\"https:\/\/www.shutterstock.com\/image-vector\/anatomy-human-eyeball-section-detailed-medical-1949570272\" data-credittext=\"Marochkina Anastasiia\/Shutterstock.com\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><figcaption class=\"wp-caption-text\"><span class=\"imagecredit\"><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.shutterstock.com\/image-vector\/anatomy-human-eyeball-section-detailed-medical-1949570272\">Marochkina Anastasiia\/Shutterstock.com<\/a><\/span><\/figcaption><\/figure>\n<p>This is where foveated rendering (literally) comes into the picture. Why render the entire scene on-screen at maximum detail when the viewer can only see that detail in a tiny part of the screen at any one time? By tracking where the viewer\u2019s fovea is pointed at any given moment, the GPU can redirect resources to that spot. This means the viewer sees a much higher quality rendered image than the available computer power is actually capable of.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Foveated_Rendering_Is_Still_Rare\"><\/span>Foveated Rendering Is Still Rare<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<figure style=\"width: 650px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-752162 size-full\" src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2021\/08\/Vive-Pro-Eye.jpg?trim=1,1&amp;bg-color=000&amp;pad=1,1\" alt=\"Vive Pro Eye Headset\" width=\"650\" height=\"395\" data-crediturl=\"https:\/\/www.vive.com\/eu\/product\/vive-pro-eye\/overview\/\" data-credittext=\"HTC\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><figcaption class=\"wp-caption-text\"><span class=\"imagecredit\"><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.vive.com\/eu\/product\/vive-pro-eye\/overview\/\">HTC<\/a><\/span><\/figcaption><\/figure>\n<p>VR headsets are the perfect platform for foveated rendering. Because the screen is str<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>ed to your head in a fixed position, it makes tracking the fovea\u2019s position relatively simple. That said, it still requires integrating relatively expensive eye-tracking technology into the headset, writing software APIs (Application Programming Interfaces), and developing <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/game\/\" data-internallinksmanager029f6b8e52c=\"7\" title=\"Game\" target=\"_blank\" rel=\"noopener\">game<\/a> engines that can take advantage of the information.<\/p>\n<p>As you can imagine,\u00a0 not many VR headsets you can buy today have eye-tracking for foveated rendering built-in. Despite this, VR hardware and software developers are clearly preparing for it.<\/p>\n<p>For example, the Oculus Quest Software Development Kit (SDK) supports <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/venturebeat.com\/2019\/12\/22\/oculus-quest-gets-dynamic-fixed-foveated-rendering\/\">fixed foveated rendering<\/a>. This is a related version of foveated rendering that doesn\u2019t rely on eye-tracking but reduces rendering detail at the periphery of the image overall. As long as the user is looking at the central part of the screen, it works well enough, but looking around the VR world without turning your head will reveal lower quality elements of the image.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Making_the_Most_of_Console_Power\"><\/span>Making the Most of Console Power<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<figure style=\"width: 1200px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-737594 size-full\" src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2021\/06\/ps5-controller-red-hero.png?trim=1,1&amp;bg-color=000&amp;pad=1,1\" alt=\"The red color variant of the DualSense PS5 controller, against a yellow background.\" width=\"1200\" height=\"675\" data-credittext=\"Sony\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><figcaption class=\"wp-caption-text\"><span class=\"imagecredit\">Sony<\/span><\/figcaption><\/figure>\n<p>Why would such a high-end feature in the VR world feature on a mainstream console VR platform? The main answer is that consoles like the PS5 have to survive for years with a fixed pool of processing power. When it comes to PC VR, it\u2019s possible to keep upgrading to more powerful hardware, using brute force to achieve the desired image quality.<\/p>\n<p>With the original PSVR for the PS4, Sony has already demonstrated that you can create <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/trip-and-travel\/\" data-internallinksmanager029f6b8e52c=\"10\" title=\"Trip &amp; Travel\" target=\"_blank\" rel=\"noopener\">trip<\/a>le-AAA VR experiences with minimal hardware if you work smart. Although the PS5\u2019s specifications are impressive today, they\u2019ll be pedestrian within a year or two, so building an efficient performance multiplier such as foveated rendering into the hardware is a sensible move even if it raises the initial hardware costs.<\/p>\n<p>If we see another mid-generation upgrade in the same vein as the PS4 Pro, it still doesn\u2019t solve the issue. After all, even if you have a more powerful console refresh, all software released for the platform still needs to run well on the original model.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"A_New_Way_to_Interact_in_VR\"><\/span>A New Way to Interact in VR<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Foveated rendering that uses eye-tracking brings more to the table than just more efficient rendering and better quality visuals. It allows for a new way to interact with VR worlds. If the software knows exactly where the user is looking within the scene, that information can be used as input. For example, it can help characters react to your gaze or trigger events, such as discovering a clue in an adventure game. That\u2019s certainly just the tip of the iceberg when it comes to the potential uses developers will come up with. Still, before VR experiences and games can integrate these mechanics, eye-tracked foveated rendering needs a wide install base.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"What_If%E2%80%A6_Foveated_Rendering_Goes_Mainstream\"><\/span>What If\u2026 Foveated Rendering Goes Mainstream?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>When the PSVR 2 is finally revealed in its final form, and it does indeed have eye-tracking and foveated rendering baked in, that could change mainstream VR in dramatic ways. Consoles effectively set the minimum requirements for cross-platform development. The first PSVR represents one of the largest VR install bases, and the PS5 is selling as fast as Sony can make them. If PSVR 2 sells at least as well as its predecessor, there\u2019s a strong incentive for VR game developers to take advantage of the system-level support for foveated rendering.<\/p>\n<p>Should all of these developments fall neatly into place, it wouldn\u2019t be surprising if the next generation of standalone and PC VR headsets also incorporate eye-tracked foveated rendering as a matter of course. If the PSVR 2 can push this next-generation feature into the mainstream, it\u2019s going to benefit the entire VR industry.<\/p>\n<\/div>\n<p><script>\n setTimeout(function(){\n  !function(f,b,e,v,n,t,s)\n  {if(f.fbq)return;n=f.fbq=function(){n.callMethod?\n  n.callMethod.apply(n,arguments):n.queue.push(arguments)};\n  if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';\n  n.queue=[];t=b.createElement(e);t.async=!0;\n  t.src=v;s=b.getElementsByTagName(e)[0];\n  s.parentNode.insertBefore(t,s) } (window, document,'script',\n  'https:\/\/connect.facebook.net\/en_US\/fbevents.js');\n   fbq('init', '335401813750447');\n   fbq('track', 'PageView');\n  },3000);\n<\/script><\/p>\n<blockquote><p><strong><span style=\"color: #ff6600;\">If you liked the article, do not forget to share it with your friends.
