Class OVRFovPort

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

    public class OVRFovPort
    extends Struct
    implements NativeResource
    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 – tangent of the angle between the viewing vector and top edge of the FOV
    • DownTan – tangent of the angle between the viewing vector and bottom edge of the FOV
    • LeftTan – tangent of the angle between the viewing vector and left edge of the FOV
    • RightTan – tangent of the angle between the viewing vector and right edge of the FOV

    Layout

    
     struct ovrFovPort {
         float UpTan;
         float DownTan;
         float LeftTan;

      • 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.
