Nets of 3D shapes The nets of 3D shapes help you see some of the properties of the shape. This net of a tetrahedron shows you the shape of each face and the number of faces.

Researchers have developed a technique that programs 2D materials to transform into complex 3D shapes.

An AI method enables the generation of sharp, high-quality 3D shapes that are closer to the quality of the best 2D image models. Previous approaches typically generated blurry or cartoonish 3D shapes.

In a 2D the answer is two, and a 3D space can be tiled in shapes that have no corners at all, called soft cells. These shapes can be made in a few different ways, and some are shown here.

Technology Robots These 2D machines can shapeshift into moving 3D robots Mori3's triangular, modular design allows it to fuse with its companions, and could one day make it into space. By Andrew Paul ...

In a blog post and papers, Facebook highlights a pair of AI models that can convert 2D objects into 3D shapes with high accuracy.
