C Specification

Bits which can be set in VkSamplerCreateInfo::flags, specifying additional parameters of a sampler, are:

typedef enum VkSamplerCreateFlagBits {
    VK_SAMPLER_CREATE_SUBSAMPLED_BIT_EXT = 0x00000001,
    VK_SAMPLER_CREATE_SUBSAMPLED_COARSE_RECONSTRUCTION_BIT_EXT = 0x00000002,
    VK_SAMPLER_CREATE_FLAG_BITS_MAX_ENUM = 0x7FFFFFFF
} VkSamplerCreateFlagBits;

Description

  • VK_SAMPLER_CREATE_SUBSAMPLED_BIT_EXT specifies that the sampler will read from an image created with flags containing VK_IMAGE_CREATE_SUBSAMPLED_BIT_EXT.

  • VK_SAMPLER_CREATE_SUBSAMPLED_COARSE_RECONSTRUCTION_BIT_EXT specifies that the implementation may use approximations when reconstructing a full color value for texture access from a subsampled image.

Note

The approximations used when VK_SAMPLER_CREATE_SUBSAMPLED_COARSE_RECONSTRUCTION_BIT_EXT is specified are implementation defined. Some implementations may interpolate between fragment density levels in a subsampled image. In that case, this bit may be used to decide whether the interpolation factors are calculated per fragment or at a coarser granularity.
