Abstract: Content-based 3D object retrieval is a challenging problem in computer vision and graphics, especially for non-rigid 3D shapes. This article proposes a multiview-based robust point ...

Shape primitive abstraction, which breaks down complex 3D forms into simple, interpretable geometric units, is fundamental to human visual perception and has important implications for computer vision ...

How a special nitinol compound and 3D printing was used to create the shape-shifting antenna. An overview of materials and heating problems they encountered, and how they overcame them. The test ...

Creating 3D shapes can be an enjoyable and educational experience, whether for school projects, design models, or creative crafts. These shapes can be made from paper, cardboard, clay, or digital ...

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 ...

MARFA, Texas, Sept 26 (Reuters) - (This Sept. 26 story has been corrected to say the area of expansion is 60 acres, not 40 acres, in paragraph 2) It looks like any other 3D printer - except it's the ...

Researchers have created microscale robots less than 1 millimeter in size that are printed as a 2D hexagonal 'metasheet' but, with a jolt of electricity, morph into preprogrammed 3D shapes and crawl.

Abstract: The segmentation of 3D shapes is a critical aspect of shape analysis. However, most existing methods for 3D shape segmentation treat each face of the original mesh model with equal ...

As an additive manufacturing method, 3D printing has been characterized by the construction of objects through the horizontal deposition of material, layer by layer. This still restricts, nonetheless, ...
