Good but…

Tetra is a good 3-D modeling software, but I wish that there was a way to import images onto the polygons or import 3-D models.

It needs work.

It’s a fairly enjoyable pastime, until it starts getting real touchy and you lose everything you were working on. Good luck getting it back. It’s too touchy. Then it becomes an annoyance.

小さい球体を操作してモデリングするようだけど全く動かせません。
ただデフォルトの立方体を眺めるだけ、、どうやるの？

FAQ

What can I do with Tetra?

Tetra allows you to easily create 3D shapes by adding and moving points. You can edit surfaces, paint colors, and utilize symmetry tools. The app also enables you to publish your artwork, share it via iCloud, and export it in formats like STL and OBJ for use with 3D printers or other editing software.

What are the main editing functions available?

Key editing functions include adding, deleting, moving, and resizing points, flipping edges of surfaces, painting and erasing colors on shapes and the floor, and using left-right and front-back symmetry. You can also manage layers, lock elements, and undo/redo actions.

How can I share my 3D creations?

You can share your artwork by exporting it in STL or OBJ format, which are compatible with 3D printers and other 3D editing applications. Additionally, you can save your work to iCloud to sync and share it across your devices.

Is Tetra free to use?

The application is free to download and use, but it does contain advertisements. There may also be in-app purchases available for additional features or content, as indicated by the monetization model.

What devices is Tetra compatible with?

Tetra is designed for mobile devices. While most features are broadly compatible, some export functions, like STL export, may not be applicable on older iPhone and iPad models such as the iPhone 5, iPhone 5C, and iPad 4th generation.
