generateDilatedDepthFromFrameCommandBuffer

public MTLTexture generateDilatedDepthFromFrameCommandBuffer(ARFrame frame,
                                                             MTLCommandBuffer commandBuffer)

Generates dilated depth at the resolution of the segmentation stencil.

The caller can use depth information when compositing a virtual object with the captured scene. This API returns the dilated linear depth to the caller. The reprojection of this depth to the caller's scene space is carried out externally.

Parameters:

frame - Current ARFrame containing camera image and estimated depth buffer. The caller is to ensure that a valid depth buffer is present.

commandBuffer - Metal command buffer for encoding depth dilation operations. The command buffer is committed by the caller externally.

Returns:

Dilated depth MTLTexture for the given ARFrame at the segmentation stencil resolution. The texture consists of a single channel and is of type float16.

generateMatteFromFrameCommandBuffer

public MTLTexture generateMatteFromFrameCommandBuffer(ARFrame frame,
                                                      MTLCommandBuffer commandBuffer)

Generates alpha matte at either full resolution or half the resolution of the captured image.

Parameters:

frame - Current ARFrame containing camera image and segmentation stencil. The caller is to ensure that a valid segmentation buffer is present.

commandBuffer - Metal command buffer for encoding matting related operations. The command buffer is committed by the caller externally.

Returns:

Alpha matte MTLTexture for the given ARFrame at full resolution or half resolution as chosen by the caller during initialization.

hash_static

public static long hash_static()

init

public ARMatteGenerator init()

Overrides:

init in class NSObject

initWithDeviceMatteResolution

public ARMatteGenerator initWithDeviceMatteResolution(MTLDevice device,
                                                      long matteResolution)

Initializes an instance of ARMatteGenerator.

For efficient creation of alpha mattes in real time it is recommended to instantiate this object only once and to generate an alpha matte for every incoming frame.

Parameters:

device - The device the filter will run on.

matteResolution - The resolution at which the matte is to be generated. Set using one of the values from 'ARMatteResolution'.

Returns:

Instance of ARMatteGenerator.
