Description

This extension enables applications to use multisampled rendering with a depth/stencil sample count that is larger than the color sample count. Having a depth/stencil sample count larger than the color sample count allows maintaining geometry and coverage information at a higher sample rate than color information. All samples are depth/stencil tested, but only the first color sample count number of samples get a corresponding color output.

VkAttachmentSampleCountInfoAMD - Structure specifying command buffer inheritance info for dynamic render pass instances

Description

If CommandBufferInheritanceInfo::renderPass is NULL_HANDLE, COMMAND_BUFFER_USAGE_RENDER_PASS_CONTINUE_BIT is specified in CommandBufferBeginInfo::flags, and the pNext chain of CommandBufferInheritanceInfo includes AttachmentSampleCountInfoAMD, then this structure defines the sample counts of each attachment within the render pass instance. If AttachmentSampleCountInfoAMD is not included, the value of CommandBufferInheritanceRenderingInfo::rasterizationSamples is used as the sample count for each attachment. If CommandBufferInheritanceInfo::renderPass is not NULL_HANDLE, or COMMAND_BUFFER_USAGE_RENDER_PASS_CONTINUE_BIT is not specified in CommandBufferBeginInfo::flags, parameters of this structure are ignored.

AttachmentSampleCountInfoAMD can also be included in the pNext chain of GraphicsPipelineCreateInfo. When a graphics pipeline is created without a RenderPass, if this structure is included in the pNext chain of GraphicsPipelineCreateInfo, it specifies the sample count of attachments used for rendering. If this structure is not specified, and the pipeline does not include a RenderPass, the value of PipelineMultisampleStateCreateInfo::rasterizationSamples is used as the sample count for each attachment. If a graphics pipeline is created with a valid RenderPass, parameters of this structure are ignored.
