Rendering a 3D model
In the computer graphics world,
rendering
is the process of illuminating a set of 3D ob-
jects with one or more imaginary lights and then creating a more-or-less realistic picture
of the results. (No, computer programmers didn't have lard on their minds when they
borrowed the word
rendering
. Hand-drawn pictures of building facades were called ren-
derings long before computers got into the act.)
A single example of this technique is called a
still rendering.
Multiple frames strung to-
gether produce computer
animation.
