C Specification
To determine if texture gather functions that take explicit LOD and/or bias
argument values can be used with a given image format, add
VkImageFormatProperties2 to the pNext
chain of the
VkPhysicalDeviceImageFormatInfo2 structure and
VkTextureLODGatherFormatPropertiesAMD to the pNext
chain of the
VkImageFormatProperties2 structure.
The VkTextureLODGatherFormatPropertiesAMD
structure is defined as:
typedef struct VkTextureLODGatherFormatPropertiesAMD {
VkStructureType sType;
void* pNext;
VkBool32 supportsTextureGatherLODBiasAMD;
} VkTextureLODGatherFormatPropertiesAMD;
Members
-
sType
is the type of this structure. -
pNext
isNULL
. -
supportsTextureGatherLODBiasAMD
tells if the image format can be used with texture gather bias/LOD functions, as introduced by thehttps://www.khronos.org/registry/vulkan/specs/1.1-extensions/html/vkspec.html#VK_AMD_texture_gather_bias_lod
extension. This field is set by the implementation. User-specified value is ignored.
