Are you a fan of 3D computer graphics and augmented reality? Then let yourself be enchanted by this metaball simulation. With [AR] Blob you get a high-quality AR app with which you can play in all facets with Metaballs. Use the settings menu. Here you will find many configuration options that influence the simulation. Choose from a variety of texture types that you like best. Change parameters to see how the simulation adapts and changes. Experiment with refraction. Consider the simulation in the virtual environment of a canyon, in the green nature, in a burned-down observatory, between heaven and earth and numerous other motifs. [AR] Blob uses the Marching Cubes algorithm, which was developed in 1987 by scientists William Lorenson and Harvey Cline as part of a research project. Virtual ISO surfaces can be found, calculated and displayed in three-dimensional space. (e.g. 3D ultrasound technology) As always, this app has no in-app purchases or annoying ads so you get a nice product. We hope you enjoy this AR title.

About

Water Simulator

Experience realistic fluid physics with particle simulation. Tap to create streams, tilt your device to control gravity, and explore various fluid types. Offers a relaxing and immersive visual experience.

Highlights
  • Realistic fluid physics simulation
  • Touch interaction for particle spawning
  • Gyroscope control for gravity direction
  • Multiple fluid presets (water, honey, oil, mercury, lava)
  • Haptic feedback for particle interaction
  • Real-time FPS display
Features
Read full description

Turn your screen into a little fluid playground. Tap to create water particles and watch them gather, flow, splash, and bounce through a touch-responsive physics simulation. POUR, WATCH, EXPERIMENT Start with the basic water simulation and 50 particles. Touch the screen to add a stream, watch how particles interact, and clear the scene when you want to begin again. Haptic feedback and an FPS readout add another layer to the experience. CHANGE THE WAY LIQUID MOVES An optional Pro subscription unlocks gyroscope gravity controls, additional fluid presets, and physics customization. Try water, honey, oil, mercury, or lava-inspired settings, then adjust available color, viscosity, surface tension, bounce, and particle-size controls. • Tilt your device to change gravity with Pro • Compare the feel of thick and thin simulated liquids • Try different particle colors and sizes • Change the physics and observe the result • Use the sandbox at your own pace, without scores or deadlines FREE AND PRO Basic water and the 50-particle tier are free to try. Pro removes the free-tier particle cap and unlocks the listed customization features; practical performance still depends on your device and simulation settings. Plans and local pricing appear before purchase. Subscriptions renew automatically unless canceled through your Apple account settings. A sensory toy for curious hands and a quiet pause. The named presets are simulated particle behaviors, not actual liquids or a laboratory measurement tool. No claim is made to diagnose or treat ADHD, anxiety, or any other condition.
