Introduction

Vive Foveated Rendering is a rendering Unity plugin which reduces the rendering work load through cutting edge GPU technologies. This plugin supports both fixed and eye-tracked foveated rendering. The developer could easily apply foveated rendering to their VR application and adjust shading rate and region size for either better performance or better quality, according to their requirements.

Features

• Foveated Rendering
• Variable Shading Rate(VRS)
• Support Eye Tracking(for VIVE Pro Eye only)

System Requirements:

• Operation System: Windows 7 with DirectX 11
• Graphics Card: NVIDIA Turing based GPUs
• Driver Version: 430 and later
• (Optional)Eye Tracking: SRAnipal v1.0.0.0

Wonderful news! Are there any plans for the unreal engine support for foveated rendering?

@andreyg Here is the answer to your question:

[Bipul]

I have two naive questions regards the foveated rendering plugin:

1. while I am importing the foveated rendering plugin from the unity asset store, I am only able to manually adjust the shading pattern and rate. But in some documentation found, the developer can even adjust the radius of each of the region (e.g., fovea, periphery). Why I cannot see that, what could be probable mistake?

 

 

 

 

 

1. If I do not want to import the foveated rendering plugin from the unity asset store, I also can download from the git. But how to import the git repository to my project?
2. I have imported a 3D scene (Sponza) and attach the ViveFoveatedRendering.cs to the main camera. However, while hitting the play button, and test with my HTC Pro Eye HMD, the camera stay static in the scene, and not moving around.

Never mind, I got it. The options are visible after hitting the play button.

I have imported the plugin into my project and I can see the different resolution of different areas.

However, I cannot see any boost in fps or any reduction in rendering time. How does this plugin reduce the rendering work load? Can anyone help?

@Cao - Yeah, you should significant perf-win. Perhaps another portion of your application is using the headroom that's being fried up to automatically increase a quality setting or feature elsewhere in your app?
