comp_layer_get_depth_swapchain()

struct xrt_swapchain * comp_layer_get_depth_swapchain	(	const struct comp_layer *	cl,
		uint32_t	swapchain_index
	)

Get a depth swapchain associated with a (projection with depth) layer.

Parameters

cla	self
swapchain_index	index of color swapchain - typically this is the view index.

References data, and xrt_layer_data::type.

comp_layer_get_swapchain()

struct xrt_swapchain * comp_layer_get_swapchain	(	const struct comp_layer *	cl,
		uint32_t	swapchain_index
	)

Get a (color) swapchain associated with a layer.

Parameters

cla	self
swapchain_index	index of swapchain - typically this is 0 for most layers, the view index for projection.

References sc_array.
