public class Media360View extends Container

A 360 degree panorama viewer: renders an equirectangular image onto the inside of a sphere with drag-to-look navigation and optional gyroscope look. Works everywhere `Display#isGpuSupported()` is true; on platforms without a GPU backend it degrades to the standard "3D not supported" placeholder without crashing.

Mono mode fills the component; `#setStereo(boolean)` renders the same viewpoint side by side for cardboard-style viewers. Photo spheres are captured from a single point, so stereo intentionally uses a zero eye separation - there is no parallax information in the image to reproduce.

360 video is not supported directly because the platform has no path from media frames to GPU textures yet; `#setTextureSource(TextureSource)` is the extension point for dynamic content.

    Media360View pano = new Media360View();
    pano.setImage(EncodedImage.create("/panorama.jpg"));
    form.add(BorderLayout.CENTER, pano);

- ## Constructor Details

  - ### Media360View

    public Media360View()
    Creates an empty viewer; supply content with `#setImage(Image)` or `#setTextureSource(TextureSource)`.

- ## Method Details

  - ### isSupported

    public boolean isSupported()
    True when the current platform provides a 3D backend.

  - ### setImage

    public void setImage(Image image)

    Shows an equirectangular panorama image (the format produced by 360 cameras and phone panorama modes: longitude maps to X, latitude to Y). Replaces any previous image or texture source.

    ###### Parameters

    - `image`: the panorama to display

  - ### setTextureSource

    public void setTextureSource(TextureSource source)

    Installs a dynamic texture source, replacing any static image. The extension point for procedural or (future) video content.

    ###### Parameters

    - `source`: the source, or null to remove it

  - ### setStereo

    public void setStereo(boolean stereo)
    Switches between a full-viewport mono view (the default) and side-by-side stereo for cardboard-style viewers.

  - ### isStereo

    public boolean isStereo()
    True when rendering side-by-side stereo.

  - ### setHeadTrackingEnabled

    public void setHeadTrackingEnabled(boolean enabled)
    Enables gyroscope look-around, composed with drag navigation. When the device has no motion sensors this quietly stays drag-only.

  - ### isHeadTrackingEnabled

    public boolean isHeadTrackingEnabled()
    True when gyroscope look-around is enabled.

  - ### getYaw

    public float getYaw()
    The horizontal look angle in degrees; positive turns right.

  - ### setYaw

    public void setYaw(float yawDegrees)
    Sets the horizontal look angle in degrees.

  - ### getPitch

    public float getPitch()
    The vertical look angle in degrees, clamped so the view cannot flip over the poles; positive looks up.

  - ### setPitch

    public void setPitch(float pitchDegrees)
    Sets the vertical look angle in degrees. Clamped to stay off the poles.

  - ### reset

    public void reset()
    Resets the view to look straight ahead and recenters the gyroscope.

  - ### getRenderView

    public RenderView getRenderView()
    The underlying render view, exposed for advanced integration.

  - ### initComponent

    protected void initComponent()
    Description copied from class: `Component`

    Overrides:
      `initComponent` in class `Component`

  - ### deinitialize

    protected void deinitialize()
    Description copied from class: `Component`
    Invoked to indicate that the component initialization is being reversed since the component was detached from the container hierarchy. This allows the component to deregister animators and cleanup after itself. This method is the opposite of the initComponent() method.

    Overrides:
      `pointerPressed` in class `Container`

  - ### pointerDragged

    public void pointerDragged(int x, int y)
    Description copied from class: `Component`

    If this Component is focused, the pointer dragged event will call this method

    ###### Parameters

    - `x`: the pointer x coordinate

    - `y`: the pointer y coordinate

    Overrides:
      `pointerDragged` in class `Component`

  - ### pointerReleased

    public void pointerReleased(int x, int y)
    Description copied from class: `Component`

    If this Component is focused, the pointer released event will call this method
