What's the difference between enable_vr_shell and enable_webvr?

[bshe, 2016/10/26 20:51:46]

enable_webvr will enable WebVR related web API and code.
enable_vr_shell will enable VrShell system UI and functionality. We also calL
VrShell ChromeVR. Mostly, we refer to our VR browser system UI controls(such as
navigation button)  and pages(such as bookmark).
Hope I explained them clearly, if not, feel free to ping me directly. And we are
probably going to ship WebVR first and then ChromeVR.

They share a lot of VR related code (such as code under vr_shell folder), which
makes them confusing. But we are hoping to remove these flags soon.
