The rise of the consumer 3D printer has yielded amazing devices for designers, engineers, hobbyists, tinkerers, and schools alike. I've been reviewing 3D printers for PCMag since the first widely ...

More affordable than ever, 3D printers are booming for personal, professional, and educational use. We've been testing them for over a decade and are here to help you find the right option. Since 2004 ...

3D reconstruction is the process of generating a computer model of the 3D (3-dimensional) appearance of an object from a set of two-dimensional images. It is common in computer vision and medicine ...

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 ...

Abstract: We report on several significant improvements to the implementation of image-based scatter correction for 3D PET and PET/CT. Among these advances are: a new algorithm to scale the estimated ...

Ubuntu users must install Python headers (apt install python3-dev) in addition to the regular python3 package. If you don't use the latest Zivid SDK version you need to manually specify the version.

A Python-based post-processing routines, called PyL3dMD, for calculating 3D molecular descriptors from molecular dynamics (MD) simulations. PyL3dMD is compatible with the popular simulation package ...

Abstract: In positron emission tomography (PET) imaging, scattered gamma photons typically account for more than 30% of total detected coincidence counts. Single scatter simulation (SSS) method is ...

Looking at something that’s more real and is happening right before your eyes can have its own charm. These days, movies have so much CGI and so much more to them that we can’t replace them with stage ...
