LWJGL 3.3.3 · org.lwjgl.vulkan.QCOMFilterCubicWeights

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
