public class KHRCreateRenderpass2
extends java.lang.Object

This extension provides a new entry point to create render passes in a way that can be easily extended by other extensions through the substructures of render pass creation. The Vulkan 1.0 render pass creation sub-structures do not include sType/pNext members. Additionally, the renderpass begin/next/end commands have been augmented with new extensible structures for passing additional subpass information.

The VkRenderPassMultiviewCreateInfo and VkInputAttachmentAspectReference structures that extended the original VkRenderPassCreateInfo are not accepted into the new creation functions, and instead their parameters are folded into this extension as follows:

• Elements of VkRenderPassMultiviewCreateInfo::pViewMasks are now specified in VkSubpassDescription2KHR::viewMask.
• Elements of VkRenderPassMultiviewCreateInfo::pViewOffsets are now specified in VkSubpassDependency2KHR::viewOffset.
• VkRenderPassMultiviewCreateInfo::correlationMaskCount and VkRenderPassMultiviewCreateInfo::pCorrelationMasks are directly specified in VkRenderPassCreateInfo2KHR.
• VkInputAttachmentAspectReference::aspectMask is now specified in the relevant input attachment description in VkAttachmentDescription2KHR::aspectMask

The details of these mappings are explained fully in the new structures.
