VkSamplerCreateInfo - Structure specifying parameters of a newly created sampler

Members

• sType is the type of this structure.

• pNext is NULL or a pointer to an extension-specific structure.
• flags is reserved for future use.
• magFilter is a VkFilter value specifying the magnification filter to apply to lookups.
• minFilter is a VkFilter value specifying the minification filter to apply to lookups.
• mipmapMode is a VkSamplerMipmapMode value specifying the mipmap filter to apply to lookups.
• addressModeU is a VkSamplerAddressMode value specifying the addressing mode for outside [0..1] range for U coordinate.
• addressModeV is a VkSamplerAddressMode value specifying the addressing mode for outside [0..1] range for V coordinate.
• addressModeW is a VkSamplerAddressMode value specifying the addressing mode for outside [0..1] range for W coordinate.
• mipLodBias is the bias to be added to mipmap LOD (level-of-detail) calculation and bias provided by image sampling functions in SPIR-V, as described in the Level-of-Detail Operation section.
• anisotropyEnable is VK_TRUE to enable anisotropic filtering, as described in the Texel Anisotropic Filtering section, or VK_FALSE otherwise.
• maxAnisotropy is the anisotropy value clamp used by the sampler when anisotropyEnable is VK_TRUE. If anisotropyEnable is VK_FALSE, maxAnisotropy is ignored.

• compareEnable is VK_TRUE to enable comparison against a reference value during lookups, or VK_FALSE otherwise.

  • Note: Some implementations will default to shader state if this member does not match.
• compareOp is a VkCompareOp value specifying the comparison function to apply to fetched data before filtering as described in the Depth Compare Operation section.
• minLod and maxLod are the values used to clamp the computed LOD value, as described in the Level-of-Detail Operation section. maxLod must be greater than or equal to minLod.
• borderColor is a VkBorderColor value specifying the predefined border color to use.

• unnormalizedCoordinates controls whether to use unnormalized or normalized texel coordinates to address texels of the image. When set to VK_TRUE, the range of the image coordinates used to lookup the texel is in the range of zero to the image dimensions for x, y and z. When set to VK_FALSE the range of image coordinates is zero to one. When unnormalizedCoordinates is VK_TRUE, samplers have the following requirements:

  • minFilter and magFilter must be equal.
  • mipmapMode must be VK_SAMPLER_MIPMAP_MODE_NEAREST.
  • minLod and maxLod must be zero.
  • addressModeU and addressModeV must each be either VK_SAMPLER_ADDRESS_MODE_CLAMP_TO_EDGE or VK_SAMPLER_ADDRESS_MODE_CLAMP_TO_BORDER.
  • anisotropyEnable must be VK_FALSE.
  • compareEnable must be VK_FALSE.
  • The sampler must not enable sampler Y’CBCR conversion.

• When unnormalizedCoordinates is VK_TRUE, images the sampler is used with in the shader have the following requirements:

  • The viewType must be either VK_IMAGE_VIEW_TYPE_1D or VK_IMAGE_VIEW_TYPE_2D.
  • The image view must have a single layer and a single mip level.

• When unnormalizedCoordinates is VK_TRUE, image built-in functions in the shader that use the sampler have the following requirements:

  • The functions must not use projection.
  • The functions must not use offsets.

Description

Note

magFilter values of VK_FILTER_NEAREST and VK_FILTER_LINEAR directly correspond to GL_NEAREST and GL_LINEAR magnification filters. minFilter and mipmapMode combine to correspond to the similarly named OpenGL minification filter of GL_minFilter_MIPMAP_mipmapMode (e.g. minFilter of VK_FILTER_LINEAR and mipmapMode of VK_SAMPLER_MIPMAP_MODE_NEAREST correspond to GL_LINEAR_MIPMAP_NEAREST).

There are no Vulkan filter modes that directly correspond to OpenGL minification filters of GL_LINEAR or GL_NEAREST, but they can be emulated using VK_SAMPLER_MIPMAP_MODE_NEAREST, minLod = 0, and maxLod = 0.25, and using minFilter = VK_FILTER_LINEAR or minFilter = VK_FILTER_NEAREST, respectively.

Note that using a maxLod of zero would cause magnification to always be performed, and the magFilter to always be used. This is valid, just not an exact match for OpenGL behavior. Clamping the maximum LOD to 0.25 allows the λ value to be non-zero and minification to be performed, while still always rounding down to the base level. If the minFilter and magFilter are equal, then using a maxLod of zero also works.

The maximum number of sampler objects which can be simultaneously created on a device is implementation-dependent and specified by the maxSamplerAllocationCount member of the VkPhysicalDeviceLimits structure. If maxSamplerAllocationCount is exceeded, vkCreateSampler will return VK_ERROR_TOO_MANY_OBJECTS.

Since VkSampler is a non-dispatchable handle type, implementations may return the same handle for sampler state vectors that are identical. In such cases, all such objects would only count once against the maxSamplerAllocationCount limit.

Valid Usage

• The absolute value of mipLodBias must be less than or equal to VkPhysicalDeviceLimits::maxSamplerLodBias

• If the anisotropic sampling feature is not enabled, anisotropyEnable must be VK_FALSE
• If anisotropyEnable is VK_TRUE, maxAnisotropy must be between 1.0 and VkPhysicalDeviceLimits::maxSamplerAnisotropy, inclusive
• If sampler Y’CBCR conversion is enabled and VK_FORMAT_FEATURE_SAMPLED_IMAGE_YCBCR_CONVERSION_SEPARATE_RECONSTRUCTION_FILTER_BIT is not set for the format, minFilter and magFilter must be equal to the sampler Y’CBCR conversion’s chromaFilter
• If unnormalizedCoordinates is VK_TRUE, minFilter and magFilter must be equal
• If unnormalizedCoordinates is VK_TRUE, mipmapMode must be VK_SAMPLER_MIPMAP_MODE_NEAREST
• If unnormalizedCoordinates is VK_TRUE, minLod and maxLod must be zero
• If unnormalizedCoordinates is VK_TRUE, addressModeU and addressModeV must each be either VK_SAMPLER_ADDRESS_MODE_CLAMP_TO_EDGE or VK_SAMPLER_ADDRESS_MODE_CLAMP_TO_BORDER
• If unnormalizedCoordinates is VK_TRUE, anisotropyEnable must be VK_FALSE
• If unnormalizedCoordinates is VK_TRUE, compareEnable must be VK_FALSE
• If any of addressModeU, addressModeV or addressModeW are VK_SAMPLER_ADDRESS_MODE_CLAMP_TO_BORDER, borderColor must be a valid VkBorderColor value
• If sampler Y’CBCR conversion is enabled, addressModeU, addressModeV, and addressModeW must be VK_SAMPLER_ADDRESS_MODE_CLAMP_TO_EDGE, anisotropyEnable must be VK_FALSE, and unnormalizedCoordinates must be VK_FALSE
• The sampler reduction mode must be set to VK_SAMPLER_REDUCTION_MODE_WEIGHTED_AVERAGE_EXT if sampler Y’CBCR conversion is enabled
• If the {html_spec_relative}#VK_KHR_sampler_mirror_clamp_to_edge extension is not enabled, addressModeU, addressModeV and addressModeW must not be VK_SAMPLER_ADDRESS_MODE_MIRROR_CLAMP_TO_EDGE
• If compareEnable is VK_TRUE, compareOp must be a valid VkCompareOp value
• If either magFilter or minFilter is VK_FILTER_CUBIC_IMG, anisotropyEnable must be VK_FALSE
• If either magFilter or minFilter is VK_FILTER_CUBIC_IMG, the reductionMode member of VkSamplerReductionModeCreateInfoEXT must be VK_SAMPLER_REDUCTION_MODE_WEIGHTED_AVERAGE_EXT
• If compareEnable is VK_TRUE, the reductionMode member of VkSamplerReductionModeCreateInfoEXT must be VK_SAMPLER_REDUCTION_MODE_WEIGHTED_AVERAGE_EXT

Valid Usage (Implicit)

• sType must be VK_STRUCTURE_TYPE_SAMPLER_CREATE_INFO

• Each pNext member of any structure (including this one) in the pNext chain must be either NULL or a pointer to a valid instance of VkSamplerReductionModeCreateInfoEXT or VkSamplerYcbcrConversionInfo
• Each sType member in the pNext chain must be unique
• flags must be 0
• magFilter must be a valid VkFilter value
• minFilter must be a valid VkFilter value
