AddDepthAttachment() [2/2]

template<typename T >

Renderer::RendererPassBuilder & Spices::Renderer::RendererPassBuilder::AddDepthAttachment	(	const std::string &	attachmentName,
		const TextureType &	type,
		T	func )

Instance a VkAttachmentDescription.

Write in data.

Parameters

[in	attachmentDescription VkAttachmentDescription.

Instance a VkClearValue. Though we reverse z depth, clear buffer with 0.0f here.

Instance a RendererResourceCreateInfo.

Get layers.

Instance a VkAttachmentReference.
