Eye track information from Varjo XR-3

[Hiroki]

Hi,

We'd like to acquire eye track data from Varjo XR-3 to be integrated Unigine engine.
how we can get these data from Unigine? What we should within Unigine project side?

In addition, we'd also like to know how to extract gaze vector data from XR-3 and how to trace these data on Unigine environment.
Would you please let me know how to do that? If there's any sample code, that would behelpful.

Best regrads,

I believe there is no direct sample related to eye tracking, but you can check the Varjo API and use it's methods in your code to get required data:

• https://developer.unigine.com/en/docs/2.18.1/api/library/plugins/class.appvarjo?rlang=cpp

In order to run your project with VR support please check this introductory paage with instructions (basically you need to run engine with -vr_app varjo start-up argument):

• https://developer.unigine.com/en/docs/2.18.1/vr_development/?rlang=cpp

Thanks!

Hi,
Thank you for your message.

I'm very the begginer of integration of code into Unigine but where we can implement code it into Unigine application?
If there's any instruction for coding, compile, debug test like that, it would be helpful for me.

>Varojo XR-4 feasibility

Varjo XR-3 seems officialy supported Unigine but XR-4 is also works on Unigine environment?

We think XR-4 probably upward compatible for XR-3 and can use XR-3's API. Let me know your thoughts.

Thank you!

You might find the "Programming" series of articles helpful which is available in our documentation at the following link: https://developer.unigine.com/en/docs/2.18.1/code/?rlang=cpp

In particular, the article "Creating C++ Application" could be especially useful: https://developer.unigine.com/en/docs/2.18.1/code/cpp/application?rlang=cpp

Additionally, there is an article dedicated to the integration with Varjo and the features it supports: https://developer.unigine.com/en/docs/2.18.1/vr_development/?rlang=cpp#integration_varjo

Moreover, the basic functionality of Varjo integration is implemented in the VR Sample demo and is available for download from the SDK: https://developer.unigine.com/en/docs/2.18.1/sdk/demos/vr_sample?rlang=cpp

Learning through it helps to gain some basic understanding of the development process with the Unigine Engine.

Currently, only XR3 is officially supported. However, as you mentioned the API has not changed and should be compatible with XR4. Please note that this compatibility has not been tested on our end so cannot be guaranteed.

Thanks!
