传统视频编辑只能在2D平面上操作，就像在照片上画画，而Shape-for-Motion能先重建出视频中物体的完整3D模型，然后在3D空间中进行精确编辑，就像操控 ...

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.

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

There are lots of different types of polygon. Find out about quadrilaterals, triangles, polygons and circles in this KS2 Maths guide from BBC Bitesize.

So what if you could buy your pasta of choice in a simple, compact 2D form and then watch it take on the desired final 3D shape as it cooks, thereby doubling the fun factor?

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.

And Iris van Herpen, a Dutch fashion designer, has (see picture) taken 3D printing to the catwalks, with striking clothing collections that reflect natural shapes and yet seem to come from a ...
