B4A Library Google VR

This library wraps the 'pano' and 'video' packages from the Google VR for Android API.
Enabling you to display mono and stereo 360° VR images and videos in your projects.

Look at the VrPanoramaView and VrVideoView objects, these are the View objects you'll use in your project.
Each View has a similarly named Options object that along with the VrWidgetViewDisplayMode object contain constants and configurations values required by various library methods.

GoogleVr
Version: 1.20
  • VrConstants
    Fields:
    • VrPanoramaViewOptions As VrPanoramaViewOptions
    • VrVideoViewOptions As VrVideoViewOptions
    • VrWidgetViewDisplayMode As VrWidgetViewDisplayMode
  • VrPanoramaView
    Events:
    • Click
    • DisplayModeChanged (NewDisplayMode As Int)
    • LoadError (ErrorMessage As String)
    • LoadSuccess
    Fields:
    • GRAVITY_BOTTOM As Int
    • GRAVITY_CENTER As Int
    • GRAVITY_CENTER_HORIZONTAL As Int
    • GRAVITY_CENTER_VERTICAL As Int
    • GRAVITY_FILL As Int
    • GRAVITY_FILL_HORIZONTAL As Int

    Methods:
    • AddView (View As View, Width As Int, Height As Int, Gravity As Int)
    • BringToFront
    • GetAllViewsRecursive As IterableList
    • GetHeadRotation (YawAndPitch() As Float)
      Provides yaw and pitch angles corresponding to where the user is looking.

      yaw is the rotation along the vertical (y) axis.
      Values are in the [-180, 180] range where:
      • 0 - looking straight at the initial image orientation.
      • 90 - looking 90 degrees to the right.
      • -90 - looking 90 degrees to the left.
      • -180 or 180 - looking in the direction opposite to the initial one

      pitch is the rotation along the right (x) axis previously rotated by yaw.
      Values are in the [-90, 90] range where:
      • 0 - looking straight, level with the ground.
      • 90 - looking up
      • -90 - looking down

      When pitch approaches 90 or -90, yaw values are reset to zero as computing the yaw values becomes numerically unstable.
    • GetView (Index As Int) As ConcreteViewWrapper
    • Initialize
      Initialize the VrWidgetView.
    • Initialize2 (EventName As String)
      Initialize the VrWidgetView and set an event listener.

    • Invalidate2 (arg0 As Rect)
    • Invalidate3 (arg0 As Int, arg1 As Int, arg2 As Int, arg3 As Int)
    • IsInitialized As Boolean
    • LoadImageFromBitmap (Bitmap1 As Bitmap, InputType As Int)
      Asynchronously loads a pano image using the given bitmap.
      The image to load should be encoded in ARGB_8888 or RGB_565 format.

      Event LoadError or LoadSuccess will be raised.
    • PauseRendering
      Pauses 3D rendering and tracking.
      This should be called in the activity's onPause() method.

      Events raised:
      Click - Called when the view has been clicked.
      DisplayModeChanged - Called when the view's display mode has changed.
      LoadError - There was an error when loading the resource.
      LoadSuccess - The resource was successfully loaded and rendering has started.
      Pass Null to clear an existing event listener.
    • SetLayout (arg0 As Int, arg1 As Int, arg2 As Int, arg3 As Int)
    • SetLayoutAnimated (arg0 As Int, arg1 As Int, arg2 As Int, arg3 As Int, arg4 As Int)

A minimum android API level of 21 is required in order to use this library.
The library also depends on 4 .aar format libraries from Google:
  • common.aar
  • commonwidget.aar
  • panowidget.aar
  • videowidget.aar
These are included in the Google VR library and (java) demo available at:
https://developers.google.com/vr/android/download.
Look in the libraries folder in the download for the .aar files and then copy them across to your b4a additional libraries folder.

There have been problem with users not downloading the current latest version of the Google VR .aar files (more info HERE).
So the 4 .aar files you require can be downloaded from Google_VR_aar_libs_20170130.zip.
These .aar files are currently version 1.10.0
I'll post a simple example next...

Library files are over 1MB in size so cannot be attached to this post. Instead download them from HERE.

    • SetLayoutAnimated (arg0 As Int, arg1 As Int, arg2 As Int, arg3 As Int, arg4 As Int)
    • SetVisibleAnimated (arg0 As Int, arg1 As Boolean)
    • SetVolume (Volume As Float)
      Sets a multiplier to the volume between 0.0f and 1.0f on the media audio playback.

      TODO do not use - method not found!
    • Shutdown
      Shuts rendering down and releases associated memory.
      Make sure you call this method before the activity is destroyed to reclaim memory. This can be typically called in the activity's onDestroy() method.
      PauseRendering() must be called prior to this function.
      The View should not be used anymore after this method has been called.

A minimum android API level of 21 is required in order to use this library.
The library also depends on 4 .aar format libraries from Google:
  • common.aar
  • commonwidget.aar
  • panowidget.aar
  • videowidget.aar
These are included in the Google VR library and (java) demo available at:
https://developers.google.com/vr/android/download.
Look in the libraries folder in the download for the .aar files and then copy them across to your b4a additional libraries folder.

There have been problem with users not downloading the current latest version of the Google VR .aar files (more info HERE).
So the 4 .aar files you require can be downloaded from Google_VR_aar_libs_20170130.zip.
These .aar files are currently version 1.10.0
I'll post a simple example next...

Library files are over 1MB in size so cannot be attached to this post. Instead download them from HERE.

Hi Warwound
First of all, thank you very much for the library.
But I am with a problem. I have tested the example on devices that have a gyroscope and accelerometer and they work great.
But there are also other devices with only an accelerometer, proving that the image cannot be moved correctly with the finger, and when it is refreshed, alternating from fullscreen mode in another space, it manages to change the point of view.
Could you please tell me how to make controls that allow finger scrolling?
Best regards
