Member Function Documentation

AquireNextImage()

VkResult Fling::Swapchain::AquireNextImage

(

const VkSemaphore &

t_CompletedSemaphore

)

ChooseSwapChainPresentMode()

VkPresentModeKHR Fling::Swapchain::ChooseSwapChainPresentMode ( const std::vector< VkPresentModeKHR > &  t_AvialableFormats )

private

Choose a present mode for the swap chain based on the given formats.

Prefer VK_PRESENT_MODE_MAILBOX_KHR If none are available, than return VK_PRESENT_MODE_FIFO_KHR or VK_PRESENT_MODE_IMMEDIATE_KHR based on support

Parameters

Vector

of available formats

Returns

Preferred present mode from the available formats

ChooseSwapChainSurfaceFormat()

VkSurfaceFormatKHR Fling::Swapchain::ChooseSwapChainSurfaceFormat ( const std::vector< VkSurfaceFormatKHR > &  t_AvailableFormats )

private

Choose a swap chain format based on the available formats.

Prefer to format that has VK_FORMAT_B8G8R8A8_UNORM and VK_COLOR_SPACE_SRGB_NONLINEAR_KHR, otherwise get the first available.

Parameters

Available

swap chain formats

Returns

Best swap chain surface formate based on the available ones

QuerySwapChainSupport()

SwapChainSupportDetails Fling::Swapchain::QuerySwapChainSupport ( )

private

Check the swap chain support of a given device.

Parameters

The	device to check support on

Returns

Details of the the swap chain support on this device

QueuePresent()

VkResult Fling::Swapchain::QueuePresent	(	const VkQueue &	t_PresentQueue,
		const VkSemaphore &	t_WaitSemaphore
	)

Recreate()

void Fling::Swapchain::Recreate

(

const VkExtent2D &

t_Extent

)

Recreate this swap chain including image views, render passes, and command buffers.

DOES NOT Clean up any resources.
