Mantis Shrimp

Mantis Shrimp is an image comparison tool written with the MetalSDK. Features: * It's a document application, so you can save your projects and open multiple windows. * It supports any types of images supported by macOS. That includes JPEG, PNG, HEIC, HDR, EXR, and others. * It supports automatic linear RGB conversions. * It supports multiple color spaces, including display-P3 (DCI-P3). * It comes with multiple presets to compare color channels in different ways. * It lets you write and use your custom shaders, using Metal shading language. These can be fragment or mesh shaders. * Shaders come with some predefined functions and variables, including time, so you can use this as a shader sandbox, or "shader toy". * The editor has some basic cpp-based syntax highlighting, with some Metal keywords. * It can record clips in mp4, for animated shaders.
