I am looking for a good mechanical algorithm
to place mechanics and inner workings in the center of the spider...?
Also looking for a good walking algorithm to animate the spider
walking on or off the screen...?
Currently the animation ( first still clock 0 spyder.jpg first frame )
opens the legs ( clock 1 ) raises the top hull ( clock 2 )
And finally expands the legs outward ( second still clock 3 spyder
30.jpg final frame )
Star Wars fans: It is supposed to look like the defense drones in E1
that roll out as balls and open to reveal the attacking spider like
drone robots...
Actually the idea is based on a CGI cartoon by "Mainframe.inc" called
war planets where these are Attacking Tanks called "Spyders" witch have
a barrage of weapons and can collapse to the ball form for defense and
camouflage on the ice planet they are to defend...

The July 1998 round of the IRTC has a robot bug walking around; it's
in 3.0 code.

Thanks for the input guys... =)
I guess if you do not have a dazzling and big picture you do not get good
feed back... =(
I will look at the IRTC as suggested...

Sorry, Someguy, this is not something I've done. Bob Hughes recently posted
a scorpion animation that may have something for you. My understanding was
that you were after something a little different from that, but you could
check out binaries.animations to find out.

I will give it a look... Thanks...",
The "microcosms" anim. in the irtc looks to have what i am looking for...
I also need a good mechanical arm code as well...

Hm, well, not really much of any real walking done in what I tried. I ended
up faking it basically. I only managed somewhat of an illusion of walking.
The legs wouldn't cooperate and walk forward convincingly I thought, and
they also refused to touch the ground correctly. All because it was done by
using a base leg object which was then rotated and translated and rotated
again.
I figure it's something to work on again sometime.
Your post here was one I hurried past and I didn't have a quick suggestion
at the moment.

I recall watching a nature show on how bugs walk. It was fascinating stuff,
but of course I didn't take notes. I intend to work on this myself, too.
I think a Centipede would be a good challenge.

IIRC, They move sets of three legs in opposing triangles.

It is actually a sine wave of impulses rotated for each side. Which
gives you the extension into centipede walking. I imagine one could use
trace to find where each foot lands and make a real insect program in POV.

Watching films of sidewinders and the tracks they leave does my head in. I
understand it for about 5 seconds while that nice Mr. Attenborough is
explaining it, and then it just looks weird again. I call this the "quantum
understanding" as a) I both understand and don't understand and b) it's the
same thing when I read up on quantum physics.
BTW that cat thing is a red herring - it either suffocated or got gassed.
