First I have a question those of you could answer, who will answer me
How long do you carry out discussions here on the list? Do you rather
private dialogue or do you keep on exchanging ideas over the mailing
Well, now to the point:
I have implemented something similar to the video Patrick Enoch has done
(thanks again by the way!). I used 4 joints over the total length of
1 of the bristles
and they already look pretty flexible. I started to simulation, one
like the one in
the video, where the brush moves vertically and one where it moves
This is IMHO the best way to determine the right values for the
BUT I have met some problems:
1. How can I switch off the texture of the plane? I only want to show
a box and
the brush above, which moves either up and down or from the left to
Therefore I don't need the plane and it is only a distraction!
2. How can I keep the position of the ground_box fixed? First I just
oszillating force to the brush, but after the first contact it was
pushed back and flew
away into the eternal heaven of the ODE-space. Then I added a
which pulls it towards the box at the ground, but when contacting,
the brush pushes
away the box through the ground. Not my intention.
That much by now. I guess The next big step will be the restoring
that is an entirely different story and will be told at another time.
