Member Function Documentation

◆ find_best_queue_family_indices()

std::vector< std::pair< uint32_t, uint8_t > > tt::gfx_device_vulkan::find_best_queue_family_indices ( vk::SurfaceKHR surface ) const

Find the minimum number of queue families to instantiate for a window. This will give priority for having the Graphics and Present in the same queue family.

It is possible this method returns an incomplete queue family set. For example without Present.

◆ get_graphics_queue() [1/2]

gfx_queue_vulkan const & tt::gfx_device_vulkan::get_graphics_queue ( ) const

noexcept

Get a graphics queue.

Always returns the first queue that can handle graphics.

◆ get_graphics_queue() [2/2]

gfx_queue_vulkan const & tt::gfx_device_vulkan::get_graphics_queue ( gfx_surface const & surface ) const

noexcept

Get a graphics queue.

Always returns the first queue that can handle both graphics and presenting; or as fallback the first graphics queue.

◆ get_present_mode()

vk::PresentModeKHR tt::gfx_device_vulkan::get_present_mode	(	gfx_surface const &	surface,
		int *	score = nullptr ) const

noexcept

Get the present mode.

Always returns the best suitable present mode.

Prioritized a double buffering mode.

Parameters

	surface	The surface to determine the present mode for.
[out]

Optional return parameter for the quality of the present mode.

◆ get_present_queue()

gfx_queue_vulkan const & tt::gfx_device_vulkan::get_present_queue ( gfx_surface const & surface ) const

noexcept

Get a present queue.

Always returns the first queue that can handle both graphics and presenting; or as fallback the first present queue.

◆ get_surface_format()

vk::SurfaceFormatKHR tt::gfx_device_vulkan::get_surface_format	(	gfx_surface const &	surface,
		int *	score = nullptr ) const

noexcept

Get the surface format.

Always returns the best suitable surface format.

Prioritizes HDR, followed by sRGB.

Parameters

	surface	The surface to determine the surface format for.
[out]

Optional return parameter for the quality of the surface format.

◆ score()

int tt::gfx_device_vulkan::score ( gfx_surface const & surface ) const

overridevirtual

Check if this device is a good match for this window.

It is possible for a window to be created that is not presentable, in case of a headless-virtual-display, however in this case it may still be able to be displayed by any device.

Returns: -1 When not viable, 0 when not presentable, positive values for increasing score.

Implements tt::gfx_device.

◆ quadIndexBuffer

vk::Buffer tt::gfx_device_vulkan::quadIndexBuffer

Shared index buffer containing indices for drawing quads.

The index buffer uses the following index order: 0, 1, 2, 2, 1, 3

2<--3
|\  ^
| \ |
v  \|
0-->1

◆ requiredExtensions

std::vector<const char *> tt::gfx_device_vulkan::requiredExtensions

List if extension required on this device.

The documentation for this class was generated from the following file:
