How it works...

Samplers control the way images are read inside shaders. They can be used separately or combined with a sampled image.

Samplers are used for a VK_DESCRIPTOR_TYPE_SAMPLER descriptor type.

Sampling parameters are specified with a variable of type VkSamplerCreateInfo like this:

VkSamplerCreateInfo sampler_create_info = { 
  VK_STRUCTURE_TYPE_SAMPLER_CREATE_INFO, 
  nullptr, 
  0, 
  mag_filter, 
  min_filter, 
  mipmap_mode, 
  u_address_mode, 
  v_address_mode, 
  w_address_mode, 
  lod_bias, 
  anisotropy_enable, 
  max_anisotropy, 
  compare_enable, 
  compare_operator, 
  min_lod, 
  max_lod, 
  border_color, 
  unnormalized_coords 
};

This variable is then provided to the function that creates the sampler:

 VkResult result = vkCreateSampler( logical_device, &sampler_create_info, ...
