“In the advent of 3D as part of the numerous studies
involved in Computer Graphics, a lot of effort has been made into
developing tools and applications that emulate real-world
environment. It has become an unstated norm that the more realistic
looking an image is, the greater the impact it has on viewers.
That, in turn, is partly true, but the real essence into creating
stunning images is to know how it would look beautiful amidst the
criteria that are present. It is not a general requirement that all
your images must look hyper realistic, you just have to know and
judge how it would look good, after all that’s what CG is all
about. And believe it or not, cheating the eye is an essential tool
of the trade.“In 3D rendering context, there are a number of ways on how to
achieve realism in your scenes, but intuitively, the use of
external renderers and advanced raytracers does help a lot in the
setup and makes the creation process a bit lighter as compared to
manually setting up lights, shaders, etc. But that comes at a
rendering time tradeoff. Unfortunately though, I won’t be taking
you to the steps on how to setup your scenes for use in external
renderers, but instead I’ll walk you through the steps on how to
achieve slightly similar effects as to that of externals with the
use of the native renderer or the internal renderer as some might
call it.”
