Rendering?

The left side is rendered the right side is the real time image in the viewport.

For those who do not know what a rendered image is.. When working in the software we are work in windows/veiwports that show a preview/rough image of the model.  The process in which the computer makes the calculations (light, fluids, or basic geometry) to compose the final image is called rendering.  An example of an un-rendered image is the pictures of the helicopter that I posted before.

The reason we can't just work with real time rendered images is because the calculations are so large that the computer has to do that it takes anywhere from a few seconds to over a hour to render one frame.  When viewing through the veiwport there is still rendering going on but such a small scale that it isn't refered to as rendering but a "real time image" instead.
