Prisms are 3D objects with a constant cross section. Pyramids are 3D objects with a flat base and which taper to a vertex. Many three-dimensional objects can be constructed from 2D nets.

For example, if the solution were only applied to the edges, only they would shrink when heated, and the disc would form a bowl-shaped object. But more complex “chemical origami” would need an ...

Specifically, MonoCon is capable of identifying 3D objects in 2D images and placing them in a "bounding box," which effectively tells the AI the outermost edges of the relevant object.

The AI research labs at Facebook, Nvidia, and startups like Threedy.ai have at various points tried their hand at the challenge of 2D-object-to-3D-shape conversion. But in a new preprint paper, a ...

Scientists have created new types of 2D nanostructured surfaces which appear as realistic 3D objects – including shading and shadows – using nano-engineering techniques. The research has been carried ...

Soon, rather than merely taking 2D photos, everyday consumers will be able to take 3D captures of real-life objects and edit their shapes and appearance as they wish, just as easily as they would ...

Each point then gives users a knob to control the object with – dragging a point changes the object’s shape, and editing the properties of a point changes the object’s appearance. Then in a process ...
