C Specification

If the pNext chain of VkSamplerCreateInfo includes a VkSamplerReductionModeCreateInfoEXT structure, then that structure includes a mode that controls how texture filtering combines texel values.

The VkSamplerReductionModeCreateInfoEXT structure is defined as:

typedef struct VkSamplerReductionModeCreateInfoEXT {
    VkStructureType              sType;
    const void*                  pNext;
    VkSamplerReductionModeEXT    reductionMode;
} VkSamplerReductionModeCreateInfoEXT;


  • sType is the type of this structure.

  • pNext is NULL or a pointer to an extension-specific structure.

  • reductionMode is a VkSamplerReductionModeEXT value controlling how texture filtering combines texel values.


If this structure is not present, reductionMode is considered to be VK_SAMPLER_REDUCTION_MODE_WEIGHTED_AVERAGE_EXT.

Valid Usage (Implicit)

  • reductionMode must be a valid VkSamplerReductionModeEXT value
