Description

VK_EXT_filter_cubic extends VK_IMG_filter_cubic.

It documents cubic filtering of other image view types. It adds new structures that can be added to the pNext chain of VkPhysicalDeviceImageFormatInfo2 and VkImageFormatProperties2 that can be used to determine which image types and which image view types support cubic filtering.

New Structures

• Extending VkImageFormatProperties2:
  • VkFilterCubicImageViewImageFormatPropertiesEXT
• Extending VkPhysicalDeviceImageFormatInfo2:
  • VkPhysicalDeviceImageViewImageFormatInfoEXT
