As you can see from these bullet points, we will explore what NPR is and why to
use it. Then, we are back to the
Photo
mode to explore the effects that can be used to
create such visualizations. Nonetheless, what is NPR?
Non-photorealistic rendering
Non-photorealistic rendering (NPR)
is the use of artistic techniques to create an
image or a movie without the realism component. In other words, the image or movie
still represents the structure or the environment, but not in a photorealistic way.
What are some artistic ways to create NPRs? There was life before 3D and proof of
this is the fantastic paintings from some famous artists that represent buildings and
places. With just a few strokes and much less detail, these artists managed to bring to
us beautiful places and times that otherwise would be lost forever.
If you are interested in seeing some examples of paintings
of buildings, search for works from the following artists:
Perrot Ferdinand-Victor, Beggrov Karl Petrovich,
Paterssen Benjamin, and Grekov Alexei Angiliyevich,
to mention a few.
What did the artists use to produce such beautiful pieces of art? We do not have only
oil paintings, but also impressionism, cell shading, stippling, cross-hatching, and
outlines, just to mention a few techniques. However, by now, you might wonder
why we should use this artistic approach. And what are the benefits?
Benefits of using NPR's illustrations
One element that characterizes NPR's illustrations is the free style, without any
constraint to precision, perfection, and fidelity. We don't paint each leaf on a tree or
every grass blade, because we only want to convey the idea of a tree or a grass field.
This is perfect for scenarios where the client only desires a simple representation of
the building or site. This kind of illustration is useful during the conceptual design
or for an outline application where no commitment to materials or other elements is
required. The only intention is to provide an idea of the conceptual design.
