public final class AMDTextureGatherBiasLod extends java.lang.Object
This extension adds two related features.Firstly, support for the following SPIR-V extension in Vulkan is added:
SPV_AMD_texture_gather_bias_lod
Secondly, the extension allows the application to query which formats can be used together with the new function prototypes introduced by the SPIR-V extension.
Examples
struct VkTextureLODGatherFormatPropertiesAMD { VkStructureType sType; const void* pNext; VkBool32 supportsTextureGatherLODBiasAMD; }; // ---------------------------------------------------------------------------------------- // How to detect if an image format can be used with the new function prototypes. VkPhysicalDeviceImageFormatInfo2 formatInfo; VkImageFormatProperties2 formatProps; VkTextureLODGatherFormatPropertiesAMD textureLODGatherSupport; textureLODGatherSupport.sType = VK_STRUCTURE_TYPE_TEXTURE_LOD_GATHER_FORMAT_PROPERTIES_AMD; textureLODGatherSupport.pNext = nullptr; formatInfo.sType = VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_IMAGE_FORMAT_INFO_2; formatInfo.pNext = nullptr; formatInfo.format = ...; formatInfo.type = ...; formatInfo.tiling = ...; formatInfo.usage = ...; formatInfo.flags = ...; formatProps.sType = VK_STRUCTURE_TYPE_IMAGE_FORMAT_PROPERTIES_2; formatProps.pNext = &textureLODGatherSupport; vkGetPhysicalDeviceImageFormatProperties2(physical_device, &formatInfo, &formatProps); if (textureLODGatherSupport.supportsTextureGatherLODBiasAMD == VK_TRUE) { // physical device supports SPV_AMD_texture_gather_bias_lod for the specified // format configuration. } else { // physical device does not support SPV_AMD_texture_gather_bias_lod for the // specified format configuration. }
