VulkanIndirectPipelineNV()

Spices::VulkanIndirectPipelineNV::VulkanIndirectPipelineNV	(	VulkanState &	vulkanState,
		const std::string &	pipelineName,
		const std::string &	materialName,
		const std::vector< VkPipeline > &	pipelineRef,
		const PipelineConfigInfo &	config )

Constructor Function. Create VkPipeline.

Parameters

[in]	vulkanState	The global VulkanState.
[in]	pipelineName	The Pipeline name.
[in]	materialName	The Reference Material name.
[in]	pipelineRef	The pipeline Reference.
[in]	config	PipelineConfigInfo.

Receive PipelineLayout from parameter.

Shader groups. We use pipeline reference here, so not need create shader group. Pass any group to create info will be fine.

Instance a VkGraphicsPipelineShaderGroupsCreateInfoNV.

Instance a VkPipelineVertexInputStateCreateInfo.

Instance a VkGraphicsPipelineCreateInfo. Only pRasterizationState must be setted in pipeline reference.

Create Pipeline.
