A real image is the collection of focus points actually made by converging/diverging rays, while a virtual image is the collection of focus points made by extensions of diverging or converging rays. In other words, a real image is an image which is located in the plane of convergence for the light rays that originate from a given object.
The magnification of the virtual image formed by the plane mirror is 1. Top: The formation of a virtual image using a diverging lens. Bottom: The formation of a virtual image using a convex mirror. In both diagrams, f is the focal point, O is the object, and I is the virtual image, shown in grey. Solid blue lines indicate (real) light rays and ...
The virtuality continuum is a continuous scale ranging between the completely virtual, a virtuality, and the completely real, reality. The reality–virtuality continuum therefore encompasses all possible variations and compositions of real and virtual objects. It has been described as a concept in new media and computer science. The concept ...
VR photography (after virtual-reality photography) is the interactive viewing of panoramic photographs, generally encompassing a 360-degree circle or a spherical view. The results is known as VR photograph (or VR photo ), 360-degree photo , [ 1 ] photo sphere , [ 2 ] or spherical photo , as well as interactive panorama or immersive panorama .
Real-time computer graphics or real-time rendering is the sub-field of computer graphics focused on producing and analyzing images in real time. The term can refer to anything from rendering an application's graphical user interface ( GUI ) to real-time image analysis , but is most often used in reference to interactive 3D computer graphics ...
Popper shows that contemporary virtual art is a further refinement of the technological art of the late twentieth century and also a departure from it. What is new about this new media art , he argues, is its humanization of technology, its emphasis on interactivity , its philosophical investigation of the real and the virtual , and its ...
As with Adobe Acrobat, Nitro PDF Pro's reader is free; but unlike Adobe's free reader, Nitro's free reader allows PDF creation (via a virtual printer driver, or by specifying a filename in the reader's interface, or by drag-'n-drop of a file to Nitro PDF Reader's Windows desktop icon); Ghostscript not needed.

In various contexts, things are often described as "virtual" when they share important functional aspects with other things (real or imagined) that are or would be described as "more real". These include the following:
