When you say 3D sculpting, you don't automatically think of using your smartphone or tablet because of their obvious limitations for a complicated process like that. But wouldn't it be really fun to try a mobile version of a 3D modeling program? Well, Autodesk, a company that is more or less an expert on 3D graphics animation, certainly thought so, and they're bringing 123D Sculpt+ to your mobile device.
Unless you've mastered the art of pinching and panning or you're best friends with your device's stylus, 3D modeling on your mobile device's capacitative touchscreens can be extremely tricky. But the app can give you a feel for what the 3D modeling programs are usually like, but this time, you can try it out on your smartphone or tablet. You can create anything you want, whether it's a spaceship, an extinct animal, a fantastical creature, all in its 3D glory, from sculpting, to shaping then on to digital painting.
But just in case you've never tried this before, the app also has some pre-made models for humans, faces, animals, etc., in case you don't want to start from scratch but would want to try out the more advanced procedures. The developer says that the skeleton builder is easy to use and can be as "easy as drawing a stick figure". The things that you make on the app can be exported as OBJ files which you can later on use on other 3D tools like Autodesk Maya or 3ds Max, in case you want to get "hardcore" again.
Rendering and modifying 3D models can be a bit heavy on the processor and memory, so you probably need a higher range smartphone or tablet to run the app properly. You can download 123D Sculpt+ for free from the Google Play Store.
