Description
This extension extends cubic filtering by adding the ability to select a set of weights. Without this extension, the weights used in cubic filtering are limited to those corresponding to a Catmull-Rom spline. This extension adds support for 3 additional spline weights.
This extension adds a new structure that can be added to the pNext
chain of VkSamplerCreateInfo that can be used to specify which set of
cubic weights are used in cubic filtering.
A similar structure can be added to the pNext chain of
VkBlitImageInfo2 to specify cubic weights used in a blit operation.
With this extension weights corresponding to the following additional splines can be selected for cubic filtered sampling and blits:
-
Zero Tangent Cardinal
-
B-Spline
-
Mitchell-Netravali
New Enum Constants
-
VK_QCOM_FILTER_CUBIC_WEIGHTS_EXTENSION_NAME -
VK_QCOM_FILTER_CUBIC_WEIGHTS_SPEC_VERSION -
Extending VkStructureType:
