I've never used 3DS, but I know it's made by the AutoCad people. In that
respect, I'd imagine that the interface is maybe more engineer oriented
(I'm only speculating.) and that it works in conjuction with AutoCad.
But any, since I've nevr used and I'm probably talking out of my a**
about the subject, I'll give you my 1 minute dissertation on why I think
Lightwave is better anyway. :)
LW has a great interface - although not necessarily intuative the very
first time a user looks at it, it take all of about a day to start
rendering some pretty cool beginner stuff.
Surfacing is one of LW's stronger points. The flexability in surfacing
could be considered one of its downfalls, however, since the intermediate
user will spend 5% of their time laying out an animation and 90% of
their time screwing with all of the different neat-o surfacing
attributes. Once you get more experienced, however, you get an idea of
what you want it to look like before you try and surface an object,
therefor wasting less time going "Hey Bob, look at this cool surface,
too!"
Modeling in LW is *excellent* if you're not expecting AutoCad. Modeling
inLW is my speciality, and I'm pretty confident that I can create almost
anything (except for the more complex organic shapes, although it's
possible) in the modeler. Boolean and Solid functions really add to its
versatility.
Lighting is very versatile too. Light types, colors, falloff (although
it's linear and not quadratic), raytrace, lense flares, intesities, etc,
etc, etc... all make for an intuative, allmost-true-to-life lighting
interface.
Shadows can be raytraced or "mapped". Mapped shadows are extremely fast,
but not as accurate. Sometimes, however, the mapped shadows are more
desireable visually that traced.
Reflection and refraction can also be raytraced. However, the refraction
unfortunately is not true to life (Ie it's not easy to make a magnifying
glass that actually works).
Objects can be morphed, along with their surfaces. They can also be
brought to ife with LW's "bones". Bones are an intuative way of
attaching 'handles' (sort of) to objects in order to bend them and twist
them. It's a decent way of doing character animation.
The present ability to write macros in AREXX make working in LW an
automated thing if you're a somewhat decent programmer in AREXX (or just
happen to have a Net account so that you can d/l someone else's
scripts). What happens to this AREXX ability when LW goes PC/SGI is
unknown to me.
Plug-in technology allows for 3rd party access to LW's functions. Look
for some really cool 3rd party products in the future.
Future additions have been promised like Inverse Kninematics (a sort of
Physics to make animating gravity, collision, etc easier).
Allen and Stuart (the <two> programmers) are realy cool guys who often
will respond to netnews posts and every once in a while to personal
questions.
The user base is wide. Objects, surfaces, scenes, scripts, hints,
images, animations, and almost everything else LW can produec can be
found on BBS's, the internet, and around the corner and down the street.
Well, do I get an A for my personal dissertation? Oh, did I mention that
the price is extremely inexpensive for the quality of the output?
