Highlights
  • Self-generating, pseudo-random color patterns
  • Pixel-level unique RGB color generation
  • Apply images as textures on 3D shapes
  • In-house music for generative art sessions
  • Save and reload custom Bloom Documents
  • Variety of 3D shape geometries

Bloom is an app that generates computational art, which means images are created by algorithms rather than by hand, but users can customize parameters to influence the results. In Bloom, textures can be generated so that every pixel has a unique color. Bloom is available for macOS and iOS, in a virtually identical experience. To give every pixel in an N×N grid its own unique RGB color, we need enough color variations. With M shades per color channel (red, green, blue), we get M³ total colors. So we choose M so that M³ matches the number of pixels, N²: N² = M³ This algorithm produces endlessly varied patterns that can be applied to a variety of 3D shapes. Feature overview: • Self-generating, pseudo-random process creates unique patterns of a rainbow of colors. • 1000x1000 dimension color profusions consisting of one million different colored pixels, with option of more or less. • Apply generated images, or any other image, as textures on 3D shapes - sphere, cube, heart and more. • Listen to our own in-house music as you watch and wait. Many 3D output options, including texture filters, shape rotation, material and lighting properties. A presets menu provides you with several sets of parameter values that you can start with and then tweak further. Use the Defaults menu item to reset all parameters to the state of Bloom on first launch. Options can be saved to and reloaded from Bloom Documents, using the Share menu. Bloom Documents are created using the Share menu item Save Bloom Sphere Document, and reloaded using the Share menu item Load Bloom Document. Bloom Documents support Quick Look Thumbnails. Quick Look thumbnails are small preview images that the operating system generates for files so you can see what’s inside without opening them. For example, when you browse your files in Finder, each Bloom Document or image may have a tiny preview showing the content or a miniature version of the 3D shape and texture. This makes it easier to identify files at a glance and quickly find what you’re looking for. Available shape geometries: sphere, torus, cube, cylinder, plane, capsule, pyramid, star, trefoil knot, exclamation heart and heart. A Music Manager enables listening to an assortment of music tracks while you wait and watch the art generate.

Grow living art in the palm of your hand. Atheria turns your iPhone and iPad into a generative art studio. Fractal flames are not drawings or videos: each one is a small genome of weighted transforms, iterated billions of times on your GPU into living structure that drifts and breathes while you watch. LOCK SCREENS THAT COME ALIVE Export any flame as a Live Photo and it blooms once each time you wake the screen. iOS does not let an app set your wallpaper, so Atheria saves it to Photos and walks you through the few steps in Settings, one at a time. One is already made and waiting, so you can see it working before you make your own. GROW FLAMES Start from a preset or an archetype family, conjure a fresh random flame, or roll Chaos to invent a brand-new species named after its own anatomy. Tap Mutate to evolve the current flame one step at a time and follow the forms wherever they lead. PAINT WITH LIVING COLOR Four colors flow through every flame. Change any of them and watch the flame take the new palette live, right behind the picker. WRITE YOUR OWN SHADERS The Studio is a real Metal playground: write a fragment shader on your phone, compile it in a tap, and watch it run full screen. No computer, no build step. KEEP AND SHARE Save flames to your Library, keep the archetypes you invent, and share any creation two ways: a Share Card image for anywhere, or a short text code another Atheria user can paste to grow the exact same living art. ON THE MAC Atheria for Mac turns your creations into living desktop wallpapers. With both apps open, Handoff carries whatever you are making straight into the Mac's matching Creator. This app is free and complete on its own. PRIVATE BY DESIGN No account, no data collection, no network calls. Everything renders and stays on your device.
