Two-dimensional (2D) shapes are completely flat. They have two dimensions – length and width. A polygon is a closed 2D shape with straight sides that meet at vertices. Polygons can be regular or ...

由香港城市大学的刘宇豪、刘方、王振伟和劳润雄教授，联合腾讯的王腾飞共同完成的这项研究，于2025年6月发表在计算机 ...

How few corners can a shape have and still tile the plane?” mathematician Gábor Domokos asked me over pizza. His deceptively simple question was about the geometry of tilings, also called ...

3D films are a strange phenomenon, one that has ebbed and flowed in popularity throughout the history of cinema. I remember attending the Cannes Film Festival in 2010 and being assured that within 12 ...

The net of a 3D shape is what it looks like if it is opened out flat. There are many types of nets for the different 3D shapes. A net is made from polygons that can be folded and joined to make a ...

To solve this problem, we introduce a deep learning-based 2D+3D vehicle paint surface appearance defect detection solution. By installing 2D/3D detection sensors on robots, we achieve comprehensive ...
