Graphics

Contain items and functions interacting with the graphics API.

This module provides wrapper around GPU primitives, such as textures, meshes and shader programs. Utilities are also provided to render screen quads, alter the rendering state and populate/save GPU data. The interface is currently based on the Vulkan API.

Namespaces
namespace	VkUtils
	Utility functions for the Vulkan backend.

Classes
class	DescriptorAllocator
	Manage descriptor set allocations by creating and reusing internal descriptor pools. More...
class	GPU
	Provide utility functions to communicate with the driver and GPU. More...
struct	ResourceToDelete
	Request for the buffered deletion of a resource. Any of the handles stored below is optional, depending on the kind of resource being deleted. More...
struct	AsyncTextureTask
	Request for an asynchronous texture download. Data has been copied from the source texture to a buffer during the frame. The readback of the buffer to the CPU has to be performed once the frame is complete. More...
struct	GPUContext
	Global GPU context, storing all structures used for resource allocation and tracking, operations recording and rendering. More...
class	GPUTexture
	Store a texture data on the GPU. More...
class	GPUBuffer
	Store data in a GPU buffer. More...
class	GPUMesh
	Store vertices and triangles data on the GPU, linked by an array object. More...
class	GPUState
	Internal GPU state ; not all API options are exposed, only these that can be toggled in Rendu. More...
class	GPUQuery
	Represent a GPU query, automatically buffered and retrieved. More...
class	GPUMarker
	Inserted a marker on the current render or upload command buffer. These markers are visible in profling and debugging tools such as Renderdoc, as are object debug labels. More...
struct	DescriptorSet
	Descriptor set allocation. More...
class	PipelineCache
	Create and reuse GPU pipelines based on a given state. This supports both graphics and compute pipelines. More...
class	Program
	Represents a group of shaders used for rendering. More...
class	QueryAllocator
	Manages GPU queries allocation in a set of pools. Pools need to be buffered per frame so that we can retrieve the previous frame queries while the current queries are running. More...
class	SamplerLibrary
	Manage all samplers for GPU textures. Samplers are shared between all shader programs, and directly specified in the shaders based on use. All samplers are stored in a unique, shared descriptor set appended to all other sets (set #3). More...
class	ShaderCompiler
	Relies on glslang to compile GLSL shaders to SPIR-V and generate reflection data. More...
class	Swapchain
	A swapchain handles the creation and presentation of the backbuffer, along with GPU work submission and synchronization. More...

Macros
#define	VK_RETURN_CHECK(F, L)   (F);
	Macro used to check the return code of Vulkan calls.
#define	VK_RET(F)   VK_RETURN_CHECK((F), __LINE__)
	Macro used to check the return code of Vulkan calls.

Functions
VKAPI_ATTR VkBool32 VKAPI_CALL	vkDebugCallback (VkDebugUtilsMessageSeverityFlagBitsEXT messageSeverity, VkDebugUtilsMessageTypeFlagsEXT messageType, const VkDebugUtilsMessengerCallbackDataEXT *callbackData, void *userData)

Function Documentation

vkDebugCallback()

VKAPI_ATTR VkBool32 VKAPI_CALL vkDebugCallback	(	VkDebugUtilsMessageSeverityFlagBitsEXT	messageSeverity,
		VkDebugUtilsMessageTypeFlagsEXT	messageType,
		const VkDebugUtilsMessengerCallbackDataEXT *	callbackData,
		void *	userData
	)

Callback for validation errors and warnings.

Parameters

messageSeverity	severity of message (error, warning,...)
messageType	type of message (validation, performance,...)
callbackData	message data, including text and ID.
userData	custom user pointer

Returns

true if the callback completed successfully
