Public Member Functions
	NsightPerfGPUProfilerHUD (VulkanState &state)
	Constructor Function.

virtual	~NsightPerfGPUProfilerHUD ()=default
	Destructor Function.

void	Create (VulkanState &state)
	Create this.

void	InitHUDRenderer ()
	Initialize ImGui, ImPlot and pass the data model into HUD Renderer.

void	RenderHUD ()
	Inform the sampler about the frame end, and use the HUD renderer to visualize the populated data model.

void	SetInSession (bool inSession)
	Set if is needed in session.

void	ConsumeSample ()
	Samples to be periodically fetched and processed by the sampler utility classes. Caveat: If this is not done, the sampler can fall into an irrecoverable state. Choose maxDecodeLatency to cover for a large-enough delay. Frame boundaries are recorded so that per-frame values, of e.g. draw call counts, can be shown as well as per-sample values.

void	EndFrame (VulkanState &state)
	End Sampler Frame.

void	Reset ()
	Reset Sampler.

Static Public Member Functions
static void	CreateInstance (VulkanState &state)
	Create this Single Instance.

static NsightPerfGPUProfilerHUD &	Get ()
	Get this Single Instance.

static void	QueryDeviceExtensionRequirement (VkInstance instance, VkPhysicalDevice physicalDevice, std::vector< const char * > &deviceExtensionNames)

static void	QueryInstanceExtensionRequirement (std::vector< const char * > &instanceExtensionNames, uint32_t apiVersion)
	Query Instance Extension Requirements.

Private Member Functions
uint32_t	SelectSamplingFrequency () const
	Select a SamplingFrequency (Hz) by ImGui::IO.

Private Attributes

	VulkanState.

nv::perf::sampler::PeriodicSamplerTimeHistoryVulkan	m_Sampler
	Sampler.

nv::perf::hud::HudDataModel	m_HudDataModel
	HUD data.

nv::perf::hud::HudImPlotRenderer	m_HudRenderer
	HUD imgui renderer.

bool	m_IsReachBufferBound
	True if Decode and Consume failed.

bool	m_IsInSession
	True if in a Session.

bool	m_IsHUDInitialized
	True id HUD is initialized.
