VkSamplerCreateFlagBits

Bitmask specifying additional parameters of sampler

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

typedef enum VkSamplerCreateFlagBits {

    // Provided by extensions
    VK_SAMPLER_CREATE_SUBSAMPLED_BIT_EXT = 0x00000001,
    VK_SAMPLER_CREATE_SUBSAMPLED_COARSE_RECONSTRUCTION_BIT_EXT = 0x00000002,
    VK_SAMPLER_CREATE_DESCRIPTOR_BUFFER_CAPTURE_REPLAY_BIT_EXT = 0x00000008,
    VK_SAMPLER_CREATE_NON_SEAMLESS_CUBE_MAP_BIT_EXT = 0x00000004,
    VK_SAMPLER_CREATE_IMAGE_PROCESSING_BIT_QCOM = 0x00000010,
} VkSamplerCreateFlagBits;

pub struct SamplerCreateFlagBits(u32);
impl SamplerCreateFlagBits {
    pub const SUBSAMPLED_EXT: Self = 0x00000001;
    pub const SUBSAMPLED_COARSE_RECONSTRUCTION_EXT: Self = 0x00000002;
    pub const DESCRIPTOR_BUFFER_CAPTURE_REPLAY_EXT: Self = 0x00000008;
    pub const NON_SEAMLESS_CUBE_MAP_EXT: Self = 0x00000004;
    pub const IMAGE_PROCESSING_QCOM: Self = 0x00000010;
}

SAMPLERS SUBSAMPLESAMPLER
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.
SAMPLERS IMAGEPROCESSINGSAMPLER
VK_SAMPLER_CREATE_IMAGE_PROCESSING_BIT_QCOM specifies that the sampler will read from images using only OpImageSampleWeightedQCOM, OpImageBoxFilterQCOM, OpImageBlockMatchGatherSSDQCOM, OpImageBlockMatchGatherSADQCOM, OpImageBlockMatchWindowSSDQCOM, OpImageBlockMatchWindowSADQCOM, OpImageBlockMatchSSDQCOM, or OpImageBlockMatchSADQCOM.

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.
