This extension requires different styles of usage, depending on -- the level of hardware support and the enabled features: -- -- - If -- 'PhysicalDeviceBlendOperationAdvancedFeaturesEXT'::@advancedBlendCoherentOperations@ -- is 'Vulkan.Core10.FundamentalTypes.FALSE', the new blending -- operations are supported, but a memory dependency /must/ separate -- each advanced blend operation on a given sample. -- 'Vulkan.Core10.Enums.AccessFlagBits.ACCESS_COLOR_ATTACHMENT_READ_NONCOHERENT_BIT_EXT' -- is used to synchronize reads using advanced blend operations. -- -- - If -- 'PhysicalDeviceBlendOperationAdvancedFeaturesEXT'::@advancedBlendCoherentOperations@ -- is 'Vulkan.Core10.FundamentalTypes.TRUE', advanced blend operations -- obey primitive order just like basic blend operations. -- -- In unextended Vulkan, the set of blending operations is limited, and -- /can/ be expressed very simply. The -- 'Vulkan.Core10.Enums.BlendOp.BLEND_OP_MIN' and -- 'Vulkan.Core10.Enums.BlendOp.BLEND_OP_MAX' blend operations simply -- compute component-wise minimums or maximums of source and destination -- color components. The 'Vulkan.Core10.Enums.BlendOp.BLEND_OP_ADD', -- 'Vulkan.Core10.Enums.BlendOp.BLEND_OP_SUBTRACT', and -- 'Vulkan.Core10.Enums.BlendOp.BLEND_OP_REVERSE_SUBTRACT' modes multiply -- the source and destination colors by source and destination factors and -- either add the two products together or subtract one from the other. -- This limited set of operations supports many common blending operations -- but precludes the use of more sophisticated transparency and blending -- operations commonly available in many dedicated imaging APIs. -- -- This extension provides a number of new “advanced” blending operations. -- Unlike traditional blending operations using -- 'Vulkan.Core10.Enums.BlendOp.BLEND_OP_ADD', these blending equations do -- not use source and destination factors specified by -- 'Vulkan.Core10.Enums.BlendFactor.BlendFactor'. Instead, each blend -- operation specifies a complete equation based on the source and -- destination colors. These new blend operations are used for both RGB and -- alpha components; they /must/ not be used to perform separate RGB and -- alpha blending (via different values of color and alpha -- 'Vulkan.Core10.Enums.BlendOp.BlendOp'). -- -- These blending operations are performed using premultiplied colors, -- where RGB colors /can/ be considered premultiplied or non-premultiplied -- by alpha, according to the @srcPremultiplied@ and @dstPremultiplied@ -- members of 'PipelineColorBlendAdvancedStateCreateInfoEXT'. If a color is -- considered non-premultiplied, the (R,G,B) color components are -- multiplied by the alpha component prior to blending. For -- non-premultiplied color components in the range [0,1], the corresponding -- premultiplied color component would have values in the range [0 × A, 1 × -- A]. -- -- Many of these advanced blending equations are formulated where the -- result of blending source and destination colors with partial coverage -- have three separate contributions: from the portions covered by both the -- source and the destination, from the portion covered only by the source, -- and from the portion covered only by the destination. The blend -- parameter 'PipelineColorBlendAdvancedStateCreateInfoEXT'::@blendOverlap@ -- /can/ be used to specify a correlation between source and destination -- pixel coverage. If set to 'BLEND_OVERLAP_CONJOINT_EXT', the source and -- destination are considered to have maximal overlap, as would be the case -- if drawing two objects on top of each other. If set to -- 'BLEND_OVERLAP_DISJOINT_EXT', the source and destination are considered -- to have minimal overlap, as would be the case when rendering a complex -- polygon tessellated into individual non-intersecting triangles. If set -- to 'BLEND_OVERLAP_UNCORRELATED_EXT', the source and destination coverage -- are assumed to have no spatial correlation within the pixel. -- -- In addition to the coherency issues on implementations not supporting -- @advancedBlendCoherentOperations@, this extension has several -- limitations worth noting. First, the new blend operations have a limit -- on the number of color attachments they /can/ be used with, as indicated -- by -- 'PhysicalDeviceBlendOperationAdvancedPropertiesEXT'::@advancedBlendMaxColorAttachments@. -- Additionally, blending precision /may/ be limited to 16-bit -- floating-point, which /may/ result in a loss of precision and dynamic -- range for framebuffer formats with 32-bit floating-point components, and -- in a loss of precision for formats with 12- and 16-bit signed or -- unsigned normalized integer components. -- -- == New Structures -- -- -
