ELI5: How does rendering work?

Is it like a painting being painted 60 times a second?

I'm asking about real-time or somewhat real time rendering, in games or in certain animation studios.

"Rendering" is a general term for converting a *general* "high level" description of something in to a *specific* instance. In the graphics example, the high-level description is a 3D model held in computer memory, while the rendering is a specific view on to that model. If it's a first person view, the "virtual camera" is at the player's location and has a fairly human-realistic field of view. 

Another example: printing is rendering. A PDF document is a rendered (printed) version of a word processor document. That's why PDFs have fixed page sizes and are hard to edit: the high-level document information has been converted to specific page-level data by the rendering process e.g the addition of margins and page breaks.
