#Cylindrical Maps
12 messages in this thread
Jack I tried the cylindrical mapping. What I got for results was the stones of
bumpy whitestone texture were spread out around the perimeter of the tube, like
they were being stretched horizontally. I make the diamter of the mapping shape
really small to try and eliminate that but it didn't seem to work. Using planar
was an act of desperation. I'm stumped why it doesn't work.
I think it may be time for you to do the Mapping tutorial (#11). It doesn't do
any good to reduce the diameter of a cylindrical map because cylindrical
mapping always wraps the bitmap, end-to-end, around the perimeter of the
object. If you want to change the horizontal scale of the bitmap, try
increasing the tiling along X using the Surface/Mapping/Adjust/Tile command.

Thanks I will try that. I thought perhaps I could just make the texture wider
in Animator but the tiling approach sounds better. BTW I did the mapping
tutorial over. It mentions a yellow and green mapping rectangle but mine is all
black. Also I found a typo on page 11-5, step 4, it should be 3ds.cel to make
sense later.

You're probably using a display driver that's incapable of displaying the
yellow and green. Check with Vibrant Graphics; they've got drivers that can
handle that now. As far as the typo… that tutorial is history.
– Jack
I'll check into that, thanks.
To get your mapping icon to look right, either use the built-in drivers or use
Panacea's freebie or Vibrant's ProRes3D drivers. The black icon is a result of
insufficiencies in the ADI spec.

I am using the built in PCPADI driver. Is it possible of doing the green and
yellow. What does ADI stand for anyway? I have the Vibrant drivers set up on
another machine and I still get a black and white mapping icon. Such problems,
so little time…not a big deal. I am just happy I figured out how to bump map
a two sided cylinder properly…and remove the caps so I can now fly through
sewers, which after all is my main goal.
Mitchell,
Maybe I'm missing something but if you wanted to fly through the pipe, it would
have been better to just make a tube not a cylinder (a tube is hollow). Then
you wouldn't have to remove the end caps (faces).

Good question Alec. I originally used 16 sided tubes but when I tried to make a
union of two intersecting tubes (to make tunnel that you could turn left or
right), I found that 3DS crashed from the operation. I got 16MB of memory so I
figured that this is just pushing too many faces at the program. When I used
cylinders the union was fast and worked great. Cylinders are nicer too in that
you don't waste faces on the "outside" where you will never see them.
Hmmmm.. . . .
Interesting info on your experience with tubes and cylinders.
Thanks,
Alec Jason

I don't know if you've got AutoCAD, but let me recommend AME (Advanced Modeling
Extentions) to you. AME is an ADS application that runs in ACAD for doing
"solid modeling". I have found that for certain things — booleans especially
— that AME is invaluable. The advantage is that you work with the primitives
BEFORE the mesh is applied to them, so you don't have to worry about
tesselating faces and whatnot. AME's got some problems, and you DO have to
worry about the sequence in which you do some union/subtract bools, but it's
really saved me some time in the past.

Hmmm. You got me! I had no problem using the VGA driver.
>>What does ADI stand for anyway?
Autodesk Device Interface, which is meant to be a standard spec that mfgs and
software developers can use to write drivers that can then communicate with the
Autodesk software. But they were really meant for AutoCAD and I guess they
didn't quite have the flexability demanded by something as different as 3DS.
>>I have the Vibrant drivers set up on another machine and I still get a

Check your version # (of the drivers). Are these AutoCAD drivers that also
provide 3DS support or are they the ProRes3D drivers? I THINK the first
version of ProRes that supported the color icons (plus the increased vector
redraw speed) was v2.1 — give a holler at Robert E. Bou 72540,1253 or Brian
Massey 71034,2611 — they're both with Vibrant (or Jack Bayt, though it seems
that his ID ain't in my address book).

Have you ever thought about therapy?<g>
