|
The mobile interface is a native VR interface that can be used on Android and iOS phones.
|
|
It contains a basic implementation supporting 3DOF tracking if a gyroscope and accelerometer are
|
|
present and sets up the proper projection matrices based on the values provided.
|
|
|
|
We're planning to eventually do separate interfaces towards mobile SDKs that have far more capabilities and
|
|
do not rely on the user providing most of these settings (though enhancing this with auto detection features
|
|
based on the device we're running on would be cool). I'm mostly adding this as an example or base plate for
|
|
more advanced interfaces.
