pAllocator controls host memory allocation as described in the Memory Allocation chapter.

-> io Sampler 

vkCreateSampler - Create a new sampler object

Valid Usage

Valid Usage (Implicit)

  • device must be a valid Device handle
  • pCreateInfo must be a valid pointer to a valid SamplerCreateInfo structure
  • If pAllocator is not NULL, pAllocator must be a valid pointer to a valid AllocationCallbacks structure
  • pSampler must be a valid pointer to a Sampler handle

withSampler :: forall a io r. (Extendss SamplerCreateInfo a, PokeChain a, MonadIO io) => Device -> SamplerCreateInfo a -> Maybe AllocationCallbacks -> (io Sampler -> (Sampler -> io ()) -> r) -> r Source #

A convenience wrapper to make a compatible pair of calls to createSampler and destroySampler

To ensure that destroySampler is always called: pass bracket (or the allocate function from your favourite resource management library) as the last argument. To just extract the pair pass (,) as the last argument.

destroySampler Source #

Arguments

:: forall io. MonadIO io 
=> Device

device is the logical device that destroys the sampler.

-> Sampler

sampler is the sampler to destroy.

-> ("allocator" ::: Maybe AllocationCallbacks)

pAllocator controls host memory allocation as described in the Memory Allocation chapter.

-> io () 

vkDestroySampler - Destroy a sampler object

Valid Usage

  • All submitted commands that refer to sampler must have completed execution
  • If AllocationCallbacks were provided when sampler was created, a compatible set of callbacks must be provided here
  • If no AllocationCallbacks were provided when sampler was created, pAllocator must be NULL

Valid Usage (Implicit)

  • device must be a valid Device handle
  • If sampler is not NULL_HANDLE, sampler must be a valid Sampler handle
  • If pAllocator is not NULL, pAllocator must be a valid pointer to a valid AllocationCallbacks structure
  • If sampler is a valid handle, it must have been created, allocated, or retrieved from device

Host Synchronization

  • Host access to sampler must be externally synchronized

data SamplerCreateInfo (es :: [Type]) Source #

VkSamplerCreateInfo - Structure specifying parameters of a newly created sampler

Description

Mapping of OpenGL to Vulkan filter modes

magFilter values of FILTER_NEAREST and FILTER_LINEAR directly correspond to GL_NEAREST and GL_LINEAR magnification filters. minFilter and mipmapMode combine to correspond to the similarly named OpenGL minification filter of GL_minFilter_MIPMAP_mipmapMode (e.g. minFilter of FILTER_LINEAR and mipmapMode of SAMPLER_MIPMAP_MODE_NEAREST correspond to GL_LINEAR_MIPMAP_NEAREST).

There are no Vulkan filter modes that directly correspond to OpenGL minification filters of GL_LINEAR or GL_NEAREST, but they can be emulated using SAMPLER_MIPMAP_MODE_NEAREST, minLod = 0, and maxLod = 0.25, and using minFilter = FILTER_LINEAR or minFilter = FILTER_NEAREST, respectively.

Note that using a maxLod of zero would cause magnification to always be performed, and the magFilter to always be used. This is valid, just not an exact match for OpenGL behavior. Clamping the maximum LOD to 0.25 allows the λ value to be non-zero and minification to be performed, while still always rounding down to the base level. If the minFilter and magFilter are equal, then using a maxLod of zero also works.

The maximum number of sampler objects which can be simultaneously created on a device is implementation-dependent and specified by the maxSamplerAllocationCount member of the PhysicalDeviceLimits structure.

Note

For historical reasons, if maxSamplerAllocationCount is exceeded, some implementations may return ERROR_TOO_MANY_OBJECTS. Exceeding this limit will result in undefined behavior, and an application should not rely on the use of the returned error code in order to identify when the limit is reached.

Since Sampler is a non-dispatchable handle type, implementations may return the same handle for sampler state vectors that are identical. In such cases, all such objects would only count once against the maxSamplerAllocationCount limit.

Valid Usage

  • The absolute value of mipLodBias must be less than or equal to PhysicalDeviceLimits::maxSamplerLodBias

Valid Usage (Implicit)

Note

The approximations used when 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.
