* Update release number to 97.
Public Issues:
* Add a special case to the <<renderpass-compatibility, Render Pass
Compatibility>> rules allowing single-subpass renderpasses to be
compatible even if they have different resolve attachment references
(public issue 835).
* Fix the miss shader binding table record address rule in the
<<shader-binding-table-indexing-rules, Miss Shaders>> section to index
by code:missIndex, not code:sbtOffset (public issue 875).
Internal Issues:
* Add a missing anchor to the elink:VkSamplerCreateFlagBits language
(internal issue 1483).
* Add missing implicit valid usage include for slink:VkHdrMetadataEXT and
corresponding `noautovalidity` attributes in `vk.xml` for the
externally-defined metadata properties (internal issue 1514).
* Remove restrictions on the `mask` parameter of SPIR-V's
code:OpGroupNonUniformXor in the <<spirvenv-module-validation,
Validation Rules within a Module>> appendix (internal merge request
2971).
* Restore `noautovalidity` attribute for
slink:VkPipelineViewportWScalingStateCreateInfoNV::pname:pViewportWScalings
in `vk.xml` (internal merge request 2975).
* Update copyright dates on Khronos-copyrighted files to 2019 (internal
merge request 2980).
New Extensions:
* `VK_KHR_depth_stencil_resolve`
* `VK_EXT_buffer_device_address`
* `VK_EXT_memory_budget`
* `VK_EXT_memory_priority`
* `VK_EXT_validation_features`

`VK_KHR_sampler_mirror_clamp_to_edge` extends the set of sampler address
|
|
modes to include an additional mode
|
|
(ename:VK_SAMPLER_ADDRESS_MODE_MIRROR_CLAMP_TO_EDGE) that effectively uses a
|
|
texture map twice as large as the original image in which the additional
|
|
half of the new image is a mirror image of the original image.
|
|
|
|
This new mode relaxes the need to generate images whose opposite edges match
|
|
by using the original image to generate a matching "`mirror image`".
|
|
This mode allows the texture to be mirrored only once in the negative s, t,
|
|
and r directions.

* Extending elink:VkSamplerAddressMode:

|
** ename:VK_SAMPLER_ADDRESS_MODE_MIRROR_CLAMP_TO_EDGE

|
=== Example
|
|
|
|
Creating a sampler with the new address mode in each dimension
|
|
|
|
|
|
[source,c++]
|
|
----------------------------------------
|
|
VkSamplerCreateInfo createInfo =
|
|
{
|
|
VK_STRUCTURE_TYPE_SAMPLER_CREATE_INFO // sType
|
|
// Other members set to application-desired values
|
|
};
|
|
|
|
createInfo.addressModeU = VK_SAMPLER_ADDRESS_MODE_MIRROR_CLAMP_TO_EDGE;
|
|
createInfo.addressModeV = VK_SAMPLER_ADDRESS_MODE_MIRROR_CLAMP_TO_EDGE;
|
|
createInfo.addressModeW = VK_SAMPLER_ADDRESS_MODE_MIRROR_CLAMP_TO_EDGE;
|
|
|
|
VkSampler sampler;
|
|
VkResult result = vkCreateSampler(
|
|
device,
|
|
&createInfo,
|
|
&sampler);
