Detailed Description

resource group for loading shader sources that give you back VkShaderModule handles

Responsibility is to load stages of shader sources whether that be through precompiler .spv files or through shaderc runtime shader compilation

Responsibility is loading and streaming the amount of bytes from the compiled shader sources into the vulkan shader module handles

resource groups up the creation and management of vulkan shader modules.

Constructor & Destructor Documentation

shader_resource_group()

atlas::vk::shader_resource_group::shader_resource_group	(	const VkDevice &	p_device,
		const ::vk::shader_resource_info &	p_info
	)

constructs a new shader_resource_group

Parameters

p_device	is the logical device required to creating the vulkan shader module
p_info	has the properties such as specified shader sources to load/compile

Member Function Documentation

handles()

std::vector<::vk::shader_handle > atlas::vk::shader_resource_group::handles ( ) const

inline

this gives you back the shader module handles along with each of their stages they have been compiled with

Returns the vector to retain the shader modules that are needed by the graphics pipeline.

It is required by vulkan specs the graphics pipeline to contain valid shader modules of the compiled shaders

Returns

vector<::vk::shader_handle>

reload_requested()

bool atlas::vk::shader_resource_group::reload_requested ( ) const

inline

ideally used for requesting for reload

Planning to use this for invalidation when for runtime shader hot-reloading

Note

this is not used at the moment as shader runtime hot reloading is currently not supported.

valid()

bool atlas::vk::shader_resource_group::valid ( ) const

inline

Returns

true if resources are valid, otherwise return false

vertex_attributes() [1/2]

std::span< const VkVertexInputAttributeDescription > atlas::vk::shader_resource_group::vertex_attributes ( ) const

inline

Returns

span<const VkVertexInputAttributeDescription>

vertex_attributes() [2/2]

void atlas::vk::shader_resource_group::vertex_attributes

(

std::span< const ::vk::vertex_attribute >

p_attributes

)

sets the vertex attributes with the shader modules that gets used by ::vk::pipeline (graphics pipeline)

Parameters

p_attributes

is the high-level specifications for setting up vertex attributes that correspond with these shaders

vertex_bind_attributes()

std::span< const VkVertexInputBindingDescription > atlas::vk::shader_resource_group::vertex_bind_attributes ( ) const

inline

Returns

span<const VkVertexInputBindingDescription>
