Real-time rendering is the one of the interactive areas of computer graphics, it means creating synthetic images fast enough on the computer so that the viewer can interact with a virtual environment. The most common place to find real-time rendering is in video games. The rate at which images are displayed is measured in frames per second (frame/s) or Hertz (Hz). The frame rate is the measurement of how quickly an imaging device produces unique consecutive images. If an application is displaying 15 frame/s it is considered real-time.
