How is VR different from a monitor

Apparently Macintosh computers cannot handle the Oculus Rift, because of their 'inferior' graphics cards. But should VR not just be like an external monitor? And concerning computer graphics, how are VR games any different from other games the…

What is "Scanline Racing"

I've heard a lot of people working on VR talk about scanline racing and that it's supposed to help improve latency for motion-to-photon. However, it isn't clear to me how this can be done with OpenGL. Could someone explain how scanline racing…

VR and frustum culling

When rendering VR ( stereo view ) environments, do you guys recommend just doing 2 frustum checks for determining what is to be drawn during the frustum culling pass or is there some other check that would be able to combine both frusta?

What methods/technologies to reduce required performance for virtual reality are there?

I'm interested in virtual reality, but according to some sources, less than 1% of computers in use today have the necessary performance to run modern VR games, granted many of them are not intended for gaming, that's still a huge barrier for the…

How can I intercept and filter all frames coming out of SteamVR?

I'm trying to investigate the effect of certain image operations on how VR scenes are perceived. To do this, I'd like to run an off-the-shelf SteamVR application, capture the frames as they come out of the compositor, run a shader or compute kernel…

Instanced Stereo Rendering vs. Multiple Command Buffers

Source In this webpage from Nvidia, the author(s) seems to imply that you could create a command buffer for each eye on separate threads. However, I don't see the benefit to this over instanced stereo rendering since you must also handle…

Is it possible to create a forced focus with a dual layer of images in order to Avoid eye strain with Virtual and Augmented Reality?

Would eye tracking allow for the alignment of a dual layered image (a google glass like device and a screen or projection) to provide a way to force the focus of the eyes into to a real life equivalent of the perceived distance in a similar, but…

Normal 2D photo to VR-compatible spherical photo

How to turn a normal photo like this one : into a photo that I can use in my game development platform (Unity3D). I just wrap a 3d sphere model with the photo and then it can be all around me when I use it in a VR headset. I know it's impossible…

Cloud based VR would be the future?

According to the following assumptions, I think Cloud based VR would be the future: 1) Real world scene rendering needs ray tracing or other complex computing graphics technologies. It needs a lot of computing power. 2) Single GPU can't afford…

Where do computer graphic engineers look for job ads?

This is kind of a meta-question: We are a neuroscience lab looking for an engineer to develop virtual environments for experiments. Since it's not our usual field of job advertisement we do not know where computer graphics people usually look for…

What is the definition of "motion to photon" in VR?

The rough definition of "MTP" is clear. But the exact one is not. You can refer to these links: What is Motion-To-Photon Latency? | chioka.in Motion-to-photon latency | xinreality.com/wiki. But from different online articles, we get different…

VR stereo rendering with Instancing

I have been reading this paper by Timothy Wilson Fast Stereo Rendering for VR and it would suit our game engine (DirectX 11) to use this method of stereo rendering. I have managed to get the game rendering Instanced and the screen squished into left…

Rendering Crystal Clear 3D Text in VR

Would it be possible to make text significantly more legible in VR? I know there are hardware limitations, but are there hanging fruit techniques that aren't being employed in 3D that are in 2D (vector based rendering, signed distance field…

Converting from 360 degree vr to rectangular

What I am interested in doing is taking a 360 degree stereo video (Oculus Rift etc), and a description of how the viewing direction changes with time (rather than reading from gyroscopes) and then rendering that to a simple side by side rectangular…

Free 3D Scene Simulation Framework

I want to visualize a scene with simple shapes (e.g. boxes, pyramides, etc.) and I am looking for a tool or framework in C/C++ to do this. Focus of the application is to parameterize the relative coordinates (position+rotation) of the scene objects.…
