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 PhysicalDeviceImageFormatInfo2 and ImageFormatProperties2 that can be used to determine which image types and which image view types support cubic filtering.

New Structures

• Extending ImageFormatProperties2:

  • FilterCubicImageViewImageFormatPropertiesEXT

• Extending PhysicalDeviceImageFormatInfo2:

  • PhysicalDeviceImageViewImageFormatInfoEXT

New Enum Constants

• EXT_FILTER_CUBIC_EXTENSION_NAME

• EXT_FILTER_CUBIC_SPEC_VERSION

• Extending Filter:

  • FILTER_CUBIC_EXT

• Extending FormatFeatureFlagBits:

  • FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_CUBIC_BIT_EXT
