Changing resolution scale on Focus

[musk]

Hi everyone,

is it possible to change the rendering resolution scale on the HTC Focus? I tried using Unity's XR Settings:

 

UnityEngine.XR.XRSettings.eyeTextureResolutionScale = scale;

 

But it doesn't do anything. Didn't find a corresponding option in WaveVR classes.

Hi ,

 

Currently it doesn't work if you revise the vaule of UnityEngine.XR.XRSettings.eyeTextureResolutionScale,  since no corresponding implementation on our Unity plugin.

Could you describe more how the use case to change resolution so we can add the proper API in our planning?

Thanks.

 

不會去吃UnityEngine.XR.XRSettings.eyeTextureResolutionScale，所以直接改這個參數並沒有作用。

目前沒開放讓使用者透過改參數的方式修改，一定是要改C#的code

Hi Tony, thanks for Your reply.

 

If you want to know the use case in my current project, I want to change the resolution to reduce aliasing by changing the rendering scale to a higher value. Although, making the scale lower to reduce resolution would also be helpful when performance is more important.

 

For example, I want to set the rendering scale to 1.5, which would render the scene in 4320 x 2400 (since regular resolution on Vive Focus is 2880 x 1600 and we multiply each by 1.5) and then downsample to the display resolution, effectively reducing aliasing. Other anti-aliasing methods didn't work for me as well as I would like, but this might help in my case.

 

In general, it would be best if we could set this rendering scale to any value, any time, even at runtime, but in my case it'd be enough if I could at least set it once for the entire project and not modify it during gameplay.

Hi ,

 

I'm informed by engineers that the change should work if you develop native app, but there might be a practical way on Unity and need to modify C# code to achieve.

Thanks.

Here is one way you might try:

 

Find Interop.WVR_GetRenderTargetSize(ref w, ref h) from WaveVR_Render.cs

The definition is w for width, and h for height.

You might try to multiply scale factor to see the result after calling this function.

Thanks.
