Is it possible to pass MTLTexture to Metal Core Image Kernel? How can Metal resources be shared with Core Image?

Answered by FrankSchlegel in 700167022

You can simply initialize a CIImage with the texture and pass that to the kernel:

let ciImage = CIImage(mtlTexture: texture)

The documentation also mentions what you need to do to let Core Image render into a Metal texture.

If you want to incorporate a Metal processing step into a Core Image pipeline instead, I recommend you check out CIImageProcessorKernel.
