pub struct SamplerBuilder<'b> { /* fields omitted */ }

A builder for Sampler.

Methods

impl<'b> SamplerBuilder<'b>

pub fn new() -> SamplerBuilder<'b>

Returns a new render pass builder.

pub fn flags<'s>(
    &'s mut self,
    flags: SamplerCreateFlags
) -> &'s mut SamplerBuilder<'b>

Reserved for future use.

pub fn mag_filter<'s>(
    &'s mut self,
    mag_filter: Filter
) -> &'s mut SamplerBuilder<'b>

Specifies the magnification filter to apply to lookups.

pub fn min_filter<'s>(
    &'s mut self,
    min_filter: Filter
) -> &'s mut SamplerBuilder<'b>

Specifies the minification filter to apply to lookups.

pub fn mipmap_mode<'s>(
    &'s mut self,
    mipmap_mode: SamplerMipmapMode
) -> &'s mut SamplerBuilder<'b>

Specifies the mipmap filter to apply to lookups.

pub fn address_mode_u<'s>(
    &'s mut self,
    address_mode_u: SamplerAddressMode
) -> &'s mut SamplerBuilder<'b>

Specifies the addressing mode for outside [0..1] range for U coordinate.

pub fn address_mode_v<'s>(
    &'s mut self,
    address_mode_v: SamplerAddressMode
) -> &'s mut SamplerBuilder<'b>

Specifies the addressing mode for outside [0..1] range for V coordinate.

pub fn address_mode_w<'s>(
    &'s mut self,
    address_mode_w: SamplerAddressMode
) -> &'s mut SamplerBuilder<'b>

Specifies the addressing mode for outside [0..1] range for W coordinate.

pub fn mip_lod_bias<'s>(
    &'s mut self,
    mip_lod_bias: f32
) -> &'s mut SamplerBuilder<'b>

Specifies the the bias to be added to mipmap LOD calculation and bias provided by image sampling functions in SPIR-V, as described in the Level-of-Detail Operation section [TODO: INSERT LINK].

pub fn anisotropy_enable<'s>(
    &'s mut self,
    anisotropy_enable: bool
) -> &'s mut SamplerBuilder<'b>

Specifies whether or not to enable anisotropic filtering, as described in the Texel Anisotropic Filtering section.

pub fn max_anisotropy<'s>(
    &'s mut self,
    max_anisotropy: f32
) -> &'s mut SamplerBuilder<'b>

Specifies the anisotropy value clamp.

pub fn compare_enable<'s>(
    &'s mut self,
    compare_enable: bool
) -> &'s mut SamplerBuilder<'b>

Specifies whether or not to enable comparison against a reference value during lookups.

Note: Some implementations will default to shader state if this member does not match.

pub fn compare_op<'s>(
    &'s mut self,
    compare_op: CompareOp
) -> &'s mut SamplerBuilder<'b>

Specifies the comparison function to apply to fetched data before filtering as described in the Depth Compare Operation section.

pub fn min_lod<'s>(&'s mut self, min_lod: f32) -> &'s mut SamplerBuilder<'b>

Specifies the minimum value used to clamp the computed level-of-detail value, as described in the Level-of-Detail Operation section. max_lod must be greater than or equal to min_lod.

pub fn max_lod<'s>(&'s mut self, max_lod: f32) -> &'s mut SamplerBuilder<'b>

Specifies the maximum value used to clamp the computed level-of-detail value, as described in the Level-of-Detail Operation section. max_lod must be greater than or equal to min_lod.

pub fn border_color<'s>(
    &'s mut self,
    border_color: BorderColor
) -> &'s mut SamplerBuilder<'b>

Specifies the predefined border color to use.

pub fn unnormalized_coordinates<'s>(
    &'s mut self,
    unnormalized_coordinates: bool
) -> &'s mut SamplerBuilder<'b>

Specifies whether to use unnormalized or normalized texel coordinates to address texels of the image. When set to VK_TRUE, the range of the image coordinates used to lookup the texel is in the range of zero to the image dimensions for x, y and z. When set to VK_FALSE the range of image coordinates is zero to one. When unnormalizedCoordinates is VK_TRUE, samplers have the following requirements:

• minFilter and magFilter must be equal.

• mipmapMode must be VK_SAMPLER_MIPMAP_MODE_NEAREST.

• minLod and maxLod must be zero.

• addressModeU and addressModeV must each be either VK_SAMPLER_ADDRESS_MODE_CLAMP_TO_EDGE or VK_SAMPLER_ADDRESS_MODE_CLAMP_TO_BORDER.

• anisotropyEnable must be VK_FALSE.

• compareEnable must be VK_FALSE.

• The sampler must not enable sampler Y’CBCR conversion.

• When unnormalizedCoordinates is VK_TRUE, images the sampler is used with in the shader have the following requirements:

  • The viewType must be either VK_IMAGE_VIEW_TYPE_1D or VK_IMAGE_VIEW_TYPE_2D.
  • The image view must have a single layer and a single mip level.

• When unnormalizedCoordinates is VK_TRUE, image built-in functions in the shader that use the sampler have the following requirements:

  • The functions must not use projection.
  • The functions must not use offsets.
