Class OVRFovPort

  • All Implemented Interfaces:
    java.lang.AutoCloseable, NativeResource, Pointer


    public class OVRFovPort
    extends Struct
    Field Of View (FOV) in tangent of the angle units. As an example, for a standard 90 degree vertical FOV, we would have:
    { UpTan = tan(90 degrees / 2), DownTan = tan(90 degrees / 2) }

    Member documentation

    • UpTan – the tangent of the angle between the viewing vector and the top edge of the field of view
    • DownTan – the tangent of the angle between the viewing vector and the bottom edge of the field of view
    • LeftTan – the tangent of the angle between the viewing vector and the left edge of the field of view
    • RightTan – the tangent of the angle between the viewing vector and the right edge of the field of view

        float UpTan;
        float DownTan;
        float LeftTan;

    • Constructor Detail

      • OVRFovPort

        public OVRFovPort(java.nio.ByteBuffer container)
        Creates a OVRFovPort instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

        The created instance holds a strong reference to the container object.
