Class EXTShaderImageAtomicInt64

java.lang.Object
org.lwjgl.vulkan.EXTShaderImageAtomicInt64
public final class EXTShaderImageAtomicInt64 extends Object
This extension extends existing 64-bit integer atomic support to enable these operations on images as well.

When working with large 2- or 3-dimensional data sets (e.g. rasterization or screen-space effects), image accesses are generally more efficient than equivalent buffer accesses. This extension allows applications relying on 64-bit integer atomics in this manner to quickly improve performance with only relatively minor code changes.

64-bit integer atomic support is guaranteed for optimally tiled images with the FORMAT_R64_UINT and FORMAT_R64_SINT formats.
