Function Documentation

client_gl_eglimage_swapchain_create()

struct xrt_swapchain* client_gl_eglimage_swapchain_create	(	struct xrt_compositor *	xc,
		const struct xrt_swapchain_create_info *	info,
		struct xrt_swapchain_native *	xscn,
		struct client_gl_swapchain **	out_sc
	)

Create a swapchain, belonging to a client_gl_compositor, that uses some way of producing an EGLImageKHR from the native buffer.

This is used on Android and on desktop when the EGL extension is used.

Todo:

this matches the behavior of the Google test, but is not itself tested or fully rationalized.

Also, glEGLImageTargetTexStorageEXT was added in Android platform 28, so fairly recently.
