API reference

SurfaceControlExt Class

Static Fields

STEREO_COMPOSITION_MONO : final int
Stereo composition mode for mono (non-stereo) rendering.
When used with setStereoComposition(SurfaceControl, Transaction, int), standard single-view buffers are allocated. This is the default mode.
Signature 
final int horizonos.view.SurfaceControlExt.STEREO_COMPOSITION_MONO
STEREO_COMPOSITION_SIDE_BY_SIDE : final int
Stereo composition mode for side-by-side stereo layout.
When used with setStereoComposition(SurfaceControl, Transaction, int), buffers with 2x width are allocated. The left half of the buffer contains the left eye content and the right half contains the right eye content.
Signature 
final int horizonos.view.SurfaceControlExt.STEREO_COMPOSITION_SIDE_BY_SIDE
STEREO_COMPOSITION_TOP_BOTTOM : final int
Stereo composition mode for top/bottom stereo layout.
When used with setStereoComposition(SurfaceControl, Transaction, int), buffers with 2x height are allocated. The left eye content should be rendered in the top half of the buffer, and the right eye content should be rendered in the bottom half. This format is commonly used for pre-rendered stereoscopic video content encoded at double height.
Signature 
final int horizonos.view.SurfaceControlExt.STEREO_COMPOSITION_TOP_BOTTOM

Static Methods

setStereoComposition ( surfaceControl , transaction , stereoComposition )
Set the SurfaceControl to render a single buffer with stereo composition.
If there's a Surface created from the requested SurfaceControl, the Surface will respect the stereo composition mode and allocate appropriately sized buffers. This API should not be used with a SurfaceControl obtained from a SurfaceView. Instead, use SurfaceViewExt.setStereoComposition(SurfaceView, int).
Signature 
static void horizonos.view.SurfaceControlExt.setStereoComposition(SurfaceControl surfaceControl, Transaction transaction, int stereoComposition)
Parameters
