C Specification

Reduction modes are specified by VkSamplerReductionModeEXT, which takes values:

typedef enum VkSamplerReductionModeEXT {
    VK_SAMPLER_REDUCTION_MODE_WEIGHTED_AVERAGE_EXT = 0,
    VK_SAMPLER_REDUCTION_MODE_MIN_EXT = 1,
    VK_SAMPLER_REDUCTION_MODE_MAX_EXT = 2,
    VK_SAMPLER_REDUCTION_MODE_MAX_ENUM_EXT = 0x7FFFFFFF
} VkSamplerReductionModeEXT;

Description

  • VK_SAMPLER_REDUCTION_MODE_WEIGHTED_AVERAGE_EXT specifies that texel values are combined by computing a weighted average of values in the footprint, using weights as specified in the image operations chapter.

  • VK_SAMPLER_REDUCTION_MODE_MIN_EXT specifies that texel values are combined by taking the component-wise minimum of values in the footprint with non-zero weights.

  • VK_SAMPLER_REDUCTION_MODE_MAX_EXT specifies that texel values are combined by taking the component-wise maximum of values in the footprint with non-zero weights.
