Thanks.

Don't know if this would help. All I can control of Peter Houston's Blobman
are the angles of the joints. Would be nice just to define a path for the
hand and let all the rest be done by an .inc-file or something. But I'll
leave that for someone who really knows what he is doing when he uses
splines.

Hm ... well ... aehm ... actually I didn't even noticed it before :-) I
thought: You have this bow, put it in his right hand! Of course you are
right that this makes him left-handed doesn't matter, does it?

Heart of Moray's IK-Plugin, but I think it won't work to well with Peter
Houstons Blobman even if it would be nice to have the computer calculate the
steps 'in between'.
I agree that the left arm is jerky and the twist of the right hand at the
end. Perhaps I can convince myself to put some more work in this - it will
be somewhat hard because all I have is an array-declaration with the
joint-angles, but as long as I have to change only the left arm it might be
possible.

of course it doesn't matter.  i was just wondering if it meant you were
left handed as well.  i guess you aren't.  have you ever done archery? 
i have.  it is a lot of fun.  i took some classes; beat my instructor at
the end-of-class competition.

No, I'm not left handed - was just too ignorant ;-) and no I have not done
archery by now. Perhaps one day.
Is my blobman doing right? Of course I bet today you used those
more-high-tech-bows with counter-weights and all but the procedure should be
quiet the same (?). And another question: where is the string connected? In
the middle of the bow? I thought so by now, but then there is an angle
between the way of the string (when released) and the arrow, because the
arrow has to avoid collision with the bow. Does the archer compensate it or
is the another mechanism to do so? Hope you understand what I mean  :-}.

you're modelling a bow between a long and a short bow.  i used a recurve
bow (although my teacher and any student who had one could use a
compound bow).  the string has a loop on each end.  the bow has grooves
cut about string diameter-deep that circle the tips about an inch away. 
here is a crude drawing:
     ____tip
     \  \
      \  \
       === groove
      | \  \
      |  \  \
string|   \  \

hope that helps.  also, the arrows have three feathers.  they are
arranged such that as they leave the bow, they look like this:

     |    |
     |    |
     |    |\
     |    | \
     |    |  \
     |    |  (0)-----
     |    |  /
     |    | /
     |    |/
     |    |
     |    |

this is the view as a lefty would see it as he fired.  the arrow is
always on the same side of the bow as your face.  the arrow does just
fine going around the bow in this manner so there is no
archer-compensation.

Thanks you very much! It's just like I imagined. I have not modeled the
groove and the loops due to laziness and the string is now "connected" at
the tip, but the rest is as it should be. Good to hear :-)

You fire a gun, you shoot a bow.

In which case, you fire bullets/pellets/slugs/shells...

Unless the bullet is being shot from a sling...

And I wouldn't have wanted to fire my bow, as it had a magnesium riser...

(clarification, three piece bows have two limbs and a riser.  You hold 
the riser, which is the central portion of the completed bow.)

Seriously, the act of propelling a projectile from a bow is called 
shooting.  Although nowadays almost nobody cares about terminology, 
unless they're one of those anal retentive archers with stabilisers in 
all directions which can pick up 35 different satellite tv channels :)

(although the club captain did a rather wonderful impersonation of 
'serious' archers which had most of the rest of the club creased up, 
except for the aforementioned 'serious' archers.)

Personally, I shot a plain three piece takedown recurve bow rated at 35 
pounds draw, which I pulled to about 45 pounds due to the length of my 
arms.  Oh, and a word of advice, backdrops don't tend to stop field point 
arrows at twenty yards very well (I only had field points at the time, 
and broke two of my arrows before I got the message...

And any comments about the 35 pounds draw being a bit on the weedy side 
will be ignored, as I was a student at the time, and couldn't afford 
anything more.

Bye for now,
     Jamie.
