#Slinky Anim ?
13 messages in this thread
Ok, I've pulled all my hair out now !!!
How would you create a slinky using morph targets. The problem I had was
getting the Bottom of the slinky object to lift off the floor.

The * is half way through the animation. The Fourth slinky will not rise from
the floor.
Could anybody give me the steps please.
Thanks

Keith,
This effect requires a bit of misdirection. Once you've made the slinky bend
over so both ends are touching the ground, you need to rotate it 180 degrees
and assign the morphs in reverse order. You rotate the slinky between two
frames (say 14 to 15) so in the final animation, the rotation is unnoticable.
Make sure the rotate keys are assigned a continuity of 0 to prevent
anticipatory motion.

I'm one of those Architects who decided to do something else to make a
living. 😉
I freelanced for four years as an AutoCAD and 3D Studio consultant and
trainer. I was a co-author of "Inside 3D Studio", and now I work at Adesk in
the Technical Publications group.

Hi Steven.
I thought it would be a good idea for Autodesk or someone like yourself to put
out a monthly mission to its blood thirsty users. Like, Who can create the
best water fall scene in 3DS without any IPAS routines and keep the size under
500K. A bit like the Who Can ??? in C++ quiz.
What do you think. It will also draw more users to the Adesk forums.

For a killer waterfall scene (completel with rainbow), check out David Schaub's
animation in the reel we'll be giving away at the Siggraph party.

Hello the Yost Group.
While your here, could you please advise me on some good IPAS add ons for
designing company logos, special effects etc..?
Can anybody advise me why when I try and link one of the sample programs
supplied with the ASL in C++ we get about 17 errors stating:
Undefined Symbols for AAPLAY
" " " AAUNLOAD
Etc…
This happens at the link stage.
Borland C++ Ver 4.x
Hi Keith,
<< While your here, could you please advise me on some good IPAS add ons for

That really depends.. Please peruse the IPAS Usage section of the library for
many demo versions and images created with IPAS routines.

keith,
have you added the directory where the ASL files are into your environment
variables for the locations of your library, header, and other files? Also,
which manf./version of C++? Also, which aspect of the ASL are you using? Also,
which sample file?

Borland C++ VER 4.02
TRYING TO COMPILE IN THE BORLAND IDE
TRYING TO ACCESS THE AAPLAY.DLL
TRIED THE SAMPLE FROM THE ASL DISKS CALLED AASHOW.
WE NEED TO COMPILE WITHIN THE IDE.
ANY HELP PLEASE.
THANKS
GEOFF
Since the unresolved symbol errors are happening at the linking stage, there
are only a few possibilites. One is that the environment variables are not
pointing to right locations for the includer files, or those files don't
exist. Another possiblity is that Borland thinks it is compiling a C++ program
and is somehow mangling the names of the symbols prior to linking. Also,
with the IDE, double check that you are using the same options as our supplied
makefiles use.

We have descovered that the error was in the AAPLAY.LIB. We had to recreate
it, using Borland C++ 4.2. The sample demo compiled and linked fine with no
errors.
You might want to check this out as an incompatability with the ASL and Borland
C++ V4.2
Thanks

Interesting idea… but I'll have to defer to Jonas or one of the sysops.
Maybe one of them can pick it up and run with it.
