C Specification

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

// Provided by VK_VERSION_1_0
typedef enum VkSamplerCreateFlagBits {
  // Provided by VK_EXT_fragment_density_map
    VK_SAMPLER_CREATE_SUBSAMPLED_BIT_EXT = 0x00000001,
  // Provided by VK_EXT_fragment_density_map
    VK_SAMPLER_CREATE_SUBSAMPLED_COARSE_RECONSTRUCTION_BIT_EXT = 0x00000002,
  // Provided by VK_EXT_descriptor_buffer
    VK_SAMPLER_CREATE_DESCRIPTOR_BUFFER_CAPTURE_REPLAY_BIT_EXT = 0x00000008,
  // Provided by VK_EXT_non_seamless_cube_map
    VK_SAMPLER_CREATE_NON_SEAMLESS_CUBE_MAP_BIT_EXT = 0x00000004,
  // Provided by VK_QCOM_image_processing
    VK_SAMPLER_CREATE_IMAGE_PROCESSING_BIT_QCOM = 0x00000010,
} 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.

  • VK_SAMPLER_CREATE_NON_SEAMLESS_CUBE_MAP_BIT_EXT specifies that cube map edge handling is not performed.

  • VK_SAMPLER_CREATE_IMAGE_PROCESSING_BIT_QCOM specifies that the sampler will read from images using only OpImageWeightedSampleQCOM, OpImageBoxFilterQCOM, OpImageBlockMatchGatherSSDQCOM, OpImageBlockMatchGatherSADQCOM, OpImageBlockMatchWindowSSDQCOM, OpImageBlockMatchWindowSADQCOM, OpImageBlockMatchSSDQCOM, or OpImageBlockMatchSADQCOM.

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.

  • VK_SAMPLER_CREATE_DESCRIPTOR_BUFFER_CAPTURE_REPLAY_BIT_EXT specifies that the sampler can be used with descriptor buffers when capturing and replaying (e.g. for trace capture and replay), see VkOpaqueCaptureDescriptorDataCreateInfoEXT for more detail.
