Luna::RHI::SamplerDesc

Describes one sampler in descriptor set.

struct Luna::RHI::SamplerDesc

Member objects

• Filter min_filter

  The filter applied when the sample pixel size is greater than texel.

• Filter mag_filter

  The filter applied when the sample pixel size is smaller than texel.

• Filter mip_filter

  The filter applied when sampling between different mipmaps.

• TextureAddressMode address_u

  The address mode used in the first direction (from left to right).

• TextureAddressMode address_v

  The address mode used in the second direction (from top to down in D3D/Vulkan, from down to top in Metal).

• TextureAddressMode address_w

  The address mode used in the third direction (from front to back in 3D textures).

• bool anisotropy_enable

  Whether to enable anisotropy sampling.

• bool compare_enable

  Whether to enable pixel comparing.

• CompareFunction compare_function

  The compare function used when compare_enable is true.

• BorderColor border_color

  The border color used when TextureAddressMode::border is set.

• u32 max_anisotropy

  The maximum anisotropy ratio.

• f32 min_lod

  The minimum LOD level that will be sampled.

• f32 max_lod

  The maximum LOD level that will be sampled. Specify one large enough value (like F32_MAX) to disable this limit.
