Detailed Description

Vulkan-specific implementation of material render resources.

This class manages Vulkan GPU resources required to render a specific Material. It provides access to the Vulkan descriptor set layout, pipeline layout, and graphics pipeline associated with a given material. The resource creation is delegated to the owning VulkanRenderer instance.

The Material class calls Initialize and Shutdown to manage the lifecycle of these resources.

Member Function Documentation

◆ GetDescriptorSetLayout()

VkDescriptorSetLayout rendering_engine::VulkanMaterialResources::GetDescriptorSetLayout ( ) const

Gets the Vulkan descriptor set layout for the material.

Returns: Vulkan handle to the descriptor set layout.

Definition at line 54 of file vulkan_material_resources.cpp.

{
    return mDescriptorSetLayout;
}

◆ GetPipeline()

VkPipeline rendering_engine::VulkanMaterialResources::GetPipeline ( ) const

Gets the Vulkan graphics pipeline used by the material.

Returns: Vulkan handle to the pipeline.

Definition at line 64 of file vulkan_material_resources.cpp.

{
    return mPipelinePair.second;
}

◆ GetPipelineLayout()

VkPipelineLayout rendering_engine::VulkanMaterialResources::GetPipelineLayout ( ) const

Gets the Vulkan pipeline layout used by the material.

Returns: Vulkan handle to the pipeline layout.

Definition at line 59 of file vulkan_material_resources.cpp.

{
    return mPipelinePair.first;
}

◆ Initialize()

void rendering_engine::VulkanMaterialResources::Initialize ( Material * material )

overridevirtual

Initializes Vulkan-specific GPU resources for the material.

Loads compiled SPIR-V shader binaries and creates descriptor set layout and pipeline.

Parameters

material Pointer to the owning Material instance.

Implements rendering_engine::IMaterialRenderResources.

    }
 
    mPipelinePair = mRenderer->CreateGraphicsPipeline(material, mDescriptorSetLayout, spvVert, spvFrag);
}

◆ Shutdown()

void rendering_engine::VulkanMaterialResources::Shutdown ( )

overridevirtual

Releases all Vulkan GPU resources associated with this material.

This should be called when the renderer shuts down or resources are rebuilt.
