VkTextureLODGatherFormatPropertiesAMD(3)

Name

VkTextureLODGatherFormatPropertiesAMD - Structure informing whether or not texture gather bias/LOD functionality is supported for a given image format and a given physical device.

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 a VkTextureLODGatherFormatPropertiesAMD structure to the pNext chain of the VkImageFormatProperties2 structure in a call to vkGetPhysicalDeviceImageFormatProperties2.

The VkTextureLODGatherFormatPropertiesAMD structure is defined as:

// Provided by VK_AMD_texture_gather_bias_lod
typedef struct VkTextureLODGatherFormatPropertiesAMD {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           supportsTextureGatherLODBiasAMD;
} VkTextureLODGatherFormatPropertiesAMD;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • supportsTextureGatherLODBiasAMD tells if the image format can be used with texture gather bias/LOD functions, as introduced by the VK_AMD_texture_gather_bias_lod extension. This field is set by the implementation. An application-specified value is ignored.

Description

Valid Usage (Implicit)

  • VUID-VkTextureLODGatherFormatPropertiesAMD-sType-sType
    sType must be VK_STRUCTURE_TYPE_TEXTURE_LOD_GATHER_FORMAT_PROPERTIES_AMD
