Hi there Product Hunt! Here's the macOS version of Effekt, a mix between an image editor and a visual toy that generates artwork in ultra high resolution. (Previously available on iOS) The artwork is generated on the GPU, using compact and blazingly fast programs known as fragment shaders. Packed with features All effects start off relatively simple, allowing the user to tweak the appearance to their liking, all while running smoothly using Apple’s Metal framework. All changes are immediately reflected on the screen, creating an instant feedback loop and fast iteration. The app comes with 30+ color schemes and a variety of image editing tools known from photography apps such as exposure, saturation, brightness and contrast, but also less common tools such as stair width, color buckets and kaleidoscope. High resolution export The app comes with a number of export formats for both video and still images, ranging from the generic 1080p, 4K and 8K as well as specific formats tailored to some of Apple's devices such as the Studio Display, the XDR Display and the Apple Watch. Technology Effekt has been under development for a long time and is built from scratch using Apple's latest rendering technologies in the Metal Framework, all using native Swift and no third-party graphics frameworks. The app itself contains only a few graphics assets, as all the art is generated in code on the GPU.
