In geometry, there are surfaces that do without an inside or outside—and some need at least four dimensions to exist ...

XREAL is wrapping up 2025 with the launch of a new entry-level AR glasses model, the XREAL 1S. It sits below the more expensive XREAL One Pro (announced in July) in the lineup and is the first in the ...

Puzzles are a hands-on way to explore simpler and complex mathematical relationships, for everyone from kids to calculus students.

A 3D shape with all straight edges and flat faces is a polyhedron. Other 3D shapes with least one curved surface are not polyhedra. A 3D shape with regular polygonal faces, meeting at equal angles, is ...

Moving from cell monolayers to three-dimensional (3D) cultures is motivated by the need to work with cellular models that mimic the functions of living tissues. Essential cellular functions that are ...

Abstract: The augmented intra-operative real-time imaging in vascular interventional surgery, which is generally performed by projecting preoperative computed tomography angiography images onto ...

We proposed a novel neural deformable model (NDM) targeting at the reconstruction and modeling of 3D bi-ventricular shape of the heart from 2D sparse cardiac magnetic resonance (CMR) imaging data. The ...

SAM 3D Objects is a foundation model that reconstructs full 3D shape geometry, texture, and layout from a single image, excelling in real-world scenarios with occlusion and clutter by using ...

Abstract: 3D Morphable Model (3DMM) fitting has widely benefited face analysis due to its strong 3D priori. However, previous reconstructed 3D faces suffer from degraded visual verisimilitude due to ...

CBeebies Creative Lab is a digital art tool for children. You can paint or draw on a blank canvas, choose line art to colour in, have fun using the spin art tool or pop bubbles to make magic pictures.
