What Does The Frame Rate Of A Virtual Reality Headset Indicate? – FutureUniverseTV Presents Practical Knowledge.
The frame rate refers to the rate at which successive images are displayed, and it is expressed as “frames per second,” or FPS. An immersive VR CAVE setup depends a lot on frame rate: The speed at which they’re shown tricks your brain into thinking they’re moving smoothly.
Monoscopic simulation frame rates. Monoscopic simulations generally require a frame rate of 60 frames per second as a minimum, while more demanding applications with fast-moving content may need 120 or even 240 frames per second to render.
Providing VR content at a high enough frame rate is one of the biggest technical challenges in order to “trick” the user into believing that they are experiencing the external world. According to research, VR setups that generate frame rates below 90 frames per second (FPS) are likely to produce disorientation, nausea, and other negative effects on the user. As the frame rate decreases, the effects become more severe.
The eye-point expected by the user for the optimal position is normally calculated in monoscopic solutions, and the virtual continuous scene is generated accordingly to give the impression that you are looking naturally into the virtual world relevant to the field of view generated by the display surface.
The frame rate of virtual reality. In order to provide sixty frames per second to each eye, stereoscopic 3D content is generally used for virtual reality CAVE room experiences at a minimum frame rate of 120Hz. In the event that more than one individual requires a dynamically corrected point of view at the same time, the frame rate demand increases.
Beyond the need for rendering at real-time frame rates, the software engine selected should also have other key characteristics. Synchronization features need to be provided so that all projectors that make up the virtual world scene around the user’s vision are updated at the same time without tearing or artifacts. Distributed rendering can be achieved using software applications, whereby separate networked PC-image generators are connected by the software in order to ensure that the visual frames of the two systems are synchronized at a software level.
Most often, this level of synchronization relies on the content being rendered efficiently with sufficient bandwidth overhead to ensure that the target frame rates are not compromised even when the visual scene on each graphics card is at its most demanding. Software alone does not always provide bulletproof synchronization. Professional simulations and Virtual Reality often require hardware level synchronization using specialist graphics cards in conjunction with the software application. Applications delivered to immersive displays must not only be able to deliver a smooth frame rate and synchronized rendering, but also provide the correct field of view for the 3D world and content generated.
As a result, the virtual camera is calculated and deployed in such a way that it provides the correct perspective to the users immersed in a true three-dimensional environment. As for hardware, this requires a graphics card (GPU) with high processing and rendering capabilities.
