Nanogenerator's 2500% stretchability sets new record

By stretching like a rubber band to more than 25 times its original length, a new nanogenerator has set a new stretchability record. The triboelectric nanogenerator's 2500% stretchability represents a significant increase ...

UK makes 'first' conviction over 3-D printed gun

A student was convicted on Wednesday of manufacturing a firearm using a 3D printer, in what London's police said they believed was the first such successful prosecution in Britain.

Image: Lunar building block

This 1.5 tonne block was 3D printed from simulated lunar dust, to demonstrate the feasibility of constructing a Moon base using local materials.

Nucleus-specific X-ray stain for 3-D virtual histology

Histology is used to identify structural details of tissue at the microscale in the pathology lab, but analyses remain two-dimensional (2D) as they are limited to the same plane. Nondestructive 3D technologies including X-ray ...

Eficient cost-effective cooling solution for high performance chips

Imec, the world-leading research and innovation hub in nano-electronics and digital technology, today announced that it has demonstrated for the first time a low-cost impingement-based solution for cooling chips at package ...

3D computer graphics

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.
