LightWave 3D 8 Texturing (Wordware Game and Graphics Library)

Buy
Before we begin to explore all the theory and techniques that are involved
in the process of texturing, it is vital to observe the world around you in
such a way as to enable you to understand exactly what you need to create
within the computer-generated environment in which you work. Merely
observing the world on a superficial level is not sufficient. Take a look
around you. What do you see? Naturally, you see the world that you have
been looking at every single day of your life.

Now take another look around you. This time, concentrate on every different
surface that you see and describe to yourself exactly what the surface
looks like. When you begin to describe what you see, you will realize that
every surface is comprised of many different qualities.

Concentrate on one particular surface. What colors are in the surface?
Are there any scratches, fingerprints, or other blemishes or imperfections
in it? Is it reflective? Does any light penetrate the surface? Answering questions
such as these will help you to understand exactly what you need to
know in order to recreate a surface such as the one that you are examining.

Look at the photo of a dusty electric guitar in Figure 1-1 on the following
page. The fingerprints in the dust tell us that someone (me!) has
recently touched it. However, the heavy layer of dust tells us that the guitar
has probably been sitting unused for some time. (I just don’t have all that
much time to practice anymore.)

Touch the surface. Is it hot or is it cold? Smooth or rough? The actual
tactile quality of the surface is very important. To make a texture believable,
you have to be able to convey to viewers exactly what the surface would
feel like if they were to reach out and touch it. The art of creating textures is
so much more than just defining the colors of surfaces; it is about creating
the quality and tangibility of them too.
