Description

This is a generic mobile VR implementation where you need to provide details about the phone and HMD used. It does not rely on any existing framework. This is the most basic interface we have. For the best effect you do need a mobile phone with a gyroscope and accelerometer.

Note that even though there is no positional tracking the camera will assume the headset is at a height of 1.85 meters, you can change this by setting eye_height.

You can initialise this interface as follows:

var interface = ARVRServer.find_interface("Native mobile")
if interface and interface.initialize():
    get_viewport().arvr = true

Property Descriptions

float display_to_lens

Setter	set_display_to_lens(value)
Getter	get_display_to_lens()

The distance between the display and the lenses inside of the device in centimeters.

float display_width

Setter	set_display_width(value)
Getter	get_display_width()

The width of the display in centimeters.

float eye_height

Setter	set_eye_height(value)
Getter	get_eye_height()

The height at which the camera is placed in relation to the ground (i.e. ARVROrigin node).

float iod

Setter	set_iod(value)
Getter	get_iod()

The interocular distance, also known as the interpupillary distance. The distance between the pupils of the left and right eye.

float k1

Setter	set_k1(value)
Getter	get_k1()

The k1 lens factor is one of the two constants that define the strength of the lens used and directly influences the lens distortion effect.

float k2

Setter	set_k2(value)
Getter	get_k2()

The k2 lens factor, see k1.

float oversample

Setter	set_oversample(value)
Getter	get_oversample()

The oversample setting. Because of the lens distortion we have to render our buffers at a higher resolution then the screen can natively handle. A value between 1.5 and 2.0 often provides good results but at the cost of performance.
