An image processing framework based on Metal.

MetalPetal is still in its early phase and isn't ready for day-to-day usage.

• Easy to use

• Performance

• Support MPS (Metal Performance Shaders)

• Support both render and compute pipeline

• Swifty

• Extensibility

• Working with CoreImage/GPUImage

Provides CommandQueue/TextureLoader/CVMetalTextureCache as well as Texture/RenderPipelineState/Function cache for rendering.

It also provides an evaluation context for MTIImages.

A recipe/promise of a MTLTexture.

A MTIImage builder.

The processing routine for MTIFilter. MTIKernel is responsible for creating the cooresponding render/compute pipeline state for the filter, and building the recipe/promise for a MTIImage.

MTIImage is designed to be immutable, so you can use a MTIImage in multiple threads.

However, MTIFilter objects are mutable and thus cannot be shared safely among threads.

MTIContext contains a lot of states and caches thus cannot be shared safely among threads currently.

We do not recommend you to use MetalPetal in your project right now.

However if you'd like to give it a try, you can use CocoaPods to install the lastest version.

use_frameworks!

pod 'MetalPetal', :git => 'https://github.com/MetalPetal/MetalPetal.git'

# Swift extensions (optional).
pod 'MetalPetal/Swift', :git => 'https://github.com/MetalPetal/MetalPetal.git'

We're going to release an alpha version of MetalPetal in Augest 2017 (hopefully).
