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.

Reality Construction Kit lets you put augmented reality objects in your real space, and play.   Toss balls, boxes and bubbles into your space - they bounce, flow, stack, rock and roll as if they're real. Tack tracks and planks into your walls, stairs and furniture and roll balls down your new course. Stack boxes, fill crates and knock them over. Toss Darts and they stick the landing. Shoot Baskets and score. Create a wild contraption made of all of these and see it work! Throughout, virtual objects realistically collide, slide, bounce, roll across surfaces, and disappear behind real ones. With uncanny collisions, reflections, shadows, and directional 3D sounds, it's the most insanely realistic augmented reality yet. The magic is enabled by a LiDAR sensor on your state-of-the-art device. As you look around, it sees the shapes in your real environment, so virtual objects can seamlessly inhabit it. "A brilliant use of the LiDAR camera on iPhone/iPad Pros. Perfectly realistic physics. Wow. Just wow." - Charlie Fink, Forbes Simple buttons let you delete recent items and try again, until your scene, course or contraption is just how you want it.   And you can get more kinds of items from the Reality Store. Reality Construction Kit brings a new generation of astonishing realistic AR you can create yourself.
