Unity XR Plugin - GLES3 support

GnoblarAgency commented 4 years ago

Currently, the XR Plugin requires that you use only the GLES2 graphics API. Is it planned to update this to GLES3?

We previously mixed Cardboard with ARCore but this is no longer possible as ARCore requires only GLES3.

Thanks for requesting the feature, adding GLES3 support is on our roadmap. Please star or watch this issue to be notified when it becomes available.

I am also facing the same issue with using ARCore and XR plugin in the same project. Please fix this or provide an alternate temporary solution.

top problem. thank you

darkverse commented 4 years ago

Yes major problem. OPENGLES3 would be a must have but are there any plans for Vulkan? Is it on the roadmap at all?

Roborino commented 4 years ago

This is a huge issue for us. We can not move forward until this is resolved. At a min we need XR Plugin to be able to use GLES3 as we are using ARCore with our application. We are on hold until this can be resolved.

What is the expected ETA?

Same Issue faced by me as well in one of our project as we use ARCore plugin and it conflicts with OPENGLES3 graphics API, Can you guys tell us how much time it will still take for an update with GLES3?

RajatPatel5 commented 4 years ago

I am using ARFoundation as well as Google Cardboard in my project. As this new XR plugin only uses OPENGLE2 which is not supported or either ARkit or ARCore we are unable to use both the plugins in our project. We also tried to use the older plugin but we are not able to resolve the references of UIWebView with it. So please suggest some ways to overcome this issue.

Instead of this plugin, I am successfully using Mobfish's plugin (https://github.com/mobfishgmbh/Cardboard-VR-Unity-SDK) with ARKit on iOS. I think the public_dev branch is suppose to be functional with Android, but I haven't tested it yet.

Same issue here, I thought OpenGLES 3.0 is backward compatible except for some minor parts: "..framebuffer objects are no longer shared between contexts, cubemaps are always filtered using seamless filtering, and there are minor changes in the way signed fixed-point numbers are converted to floating-point numbers." source

Is it possible to get an update? Our project is currently on hold until this is resolved.

@jballoffet understood that it does not support Vulkan.

Is it possible to get a date when it will support GLES3?

I expect that adding support for GLES 3.2 is a straightforward shader rewrite that you can do. We include shaders in native code in distortion_renderer.cc and in cardboard_xr_unity.cc. You could also backport ARCore to GLES2 as there's also nothing major in the implementation tying it to GLES3.2. For ARCore I also expect rewriting the shaders to be GLES2 compatible would be sufficient.

I mention this because we're prioritizing issues such as Issue #11 (Metal support) Issue #35 (Requiring Unity Pro) in front of GLES3 support. I hope this unblocks you. 😄
