(Phys.org) -- Philosophers have debated the nature of time long before Einstein and modern physics. But in the 106 years since Einstein, the prevailing view in physics has been that time serves as the fourth dimension of ...
(PhysOrg.com) -- US scientists have introduced a concept design of the "Cornucopia" or Digital Fabricator, a "personal food factory" able to print food from specified ingredients, with no waste at the point of cooking.
Three engineering physics students at the University of British Columbia have developed a desktop plastic recycler and extruder that turns plastic waste into the material needed for 3D printing.

(PhysOrg.com) -- Researchers from the University of Tokyo have developed 3D holograms that can be touched with bare hands. Generally, holograms can't be felt because they're made only of light. But the new technology adds ...
(PhysOrg.com) -- Stream TV Networks plans to introduce a line of products that feature 3-D viewing without glasses. What’s so special about its announcement, on top of scores of 3-D-without-glasses announcements? The ...
For the first time, scientists working at the National Institute of Standards and Technology have demonstrated a new type of lens that bends and focuses ultraviolet (UV) light in such an unusual way that it can create ghostly, ...

3D computer graphics (in contrast to 2D computer graphics) are graphics that use a three-dimensional representation of geometric data (often Cartesian) that is stored in the computer for the purposes of performing calculations and rendering 2D images. Such images may be for later display or for real-time viewing.
Despite these differences, 3D computer graphics rely on many of the same algorithms as 2D computer vector graphics in the wire-frame model and 2D computer raster graphics in the final rendered display. In computer graphics software, the distinction between 2D and 3D is occasionally blurred; 2D applications may use 3D techniques to achieve effects such as lighting, and primarily 3D may use 2D rendering techniques.
3D computer graphics are often referred to as 3D models. Apart from the rendered graphic, the model is contained within the graphical data file. However, there are differences. A 3D model is the mathematical representation of any three-dimensional object (either inanimate or living). A model is not technically a graphic until it is visually displayed. Due to 3D printing, 3D models are not confined to virtual space. A model can be displayed visually as a two-dimensional image through a process called 3D rendering, or used in non-graphical computer simulations and calculations.
