|
<P>Instead of a frequently asked questions section, here is information
|
|
about some of the (almost embarassing) problems faced.

</H2>
|
|
|
|
<P>The most frustrating problem, initially, was trying to figure out why
|
|
everything was black -- and then how to actually light objects up. In
|
|
these "virtual worlds" where you are modelling objects, the worlds
|
|
are created from scratch. There is <EM>no light</EM> in the world until
|
|
you actually put a light source in it! The light sources then shine
|
|
a given direction, illuminating things in their path (according to
|
|
the surface properties of the objects). Make certain that your light
|
|
source is:

|
<P>
|
|
<OL>
|
|
<LI>pointing (rotated and translated) in the correct direction;</LI>
|
|
<LI>intense enough to actually cast discernable lighting.</LI>

|
|
|
|
<P>The most basic thing a person would want to do with modelling/rendering
|
|
packages is position a sphere on a surface, give it some lighting, and
|
|
see the result. A decent tutorial should describe that first.
|
|
<P>That said, <EM>The Mops</EM> has a wonderful
