VkSamplerReductionMode

Specify reduction mode for texture filtering

Reduction modes are specified by VkSamplerReductionMode, which takes values:

typedef enum VkSamplerReductionMode {
    VK_SAMPLER_REDUCTION_MODE_WEIGHTED_AVERAGE = 0,
    VK_SAMPLER_REDUCTION_MODE_MIN = 1,
    VK_SAMPLER_REDUCTION_MODE_MAX = 2,
} VkSamplerReductionMode;

or the equivalent

#define VkSamplerReductionModeEXT VkSamplerReductionMode
  • VK_SAMPLER_REDUCTION_MODE_WEIGHTED_AVERAGE 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 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 specifies that texel values are combined by taking the component-wise maximum of values in the footprint with non-zero weights.
  • VK_SAMPLER_REDUCTION_MODE_WEIGHTED_AVERAGE_RANGECLAMP_QCOM specifies values are combined as described by VK_SAMPLER_REDUCTION_MODE_WEIGHTED_AVERAGE, followed by a texel range clamp.
