Skeletal animations?

[Dilvish]

LDD is great for creating static animations. However, are there skeletal animations for minifigs as well? Can they be hacked from one of TLG's many video games?

You mean like bending body and parts like TLG does?

[Dilvish]

Yes, precisely.

Well I did saw there was a way to warp bricks via LXFML edit like here:

With matrix modification in LXFML you can do linear transformations of parts, eg. scale them (with different scaling in each direction), rotate, slant or mirror them. But you can't distort the overall shape (eg it's not possible to introduce a joint in the middle of a leg part).

Could you give it a try with lets say torso?

[Philo]

Here is an example with a slanted torso. Rename the attached files as .lfxml to open them in LDD. skel2 is the slanted version, skel1 the straight one for comparison. But it's very difficult to do this kind of things with LDD (collision detection comes in the way), it would be much easier to do with LDraw system!

skel1.txt

skel2.txt

Thats interesting! Can you describe a bit how you do this so I can play around?

Well... I just edited the file with a text editor and modified the transformation matrix.

   <Brick refID="0" designID="6260" itemNos="626001">
  <Part refID="0" designID="6260" materials="1">
    <Bone refID="0" transformation="1,0,0,0,1,0,0,0,1,-2.7999999523162842,0.24989999830722809,-1.2000000476837158">
    </Bone>
  </Part>
   </Brick>

is changed to

   <Brick refID="0" designID="6260" itemNos="626001">
  <Part refID="0" designID="6260" materials="1">
    <Bone refID="0" transformation="1,0,0,.5,1,0,0,0,1,-2.7999999523162842,0.24989999830722809,-1.2000000476837158">
    </Bone>
  </Part>
   </Brick>

There is a tutorial about this kind of transformation here. Sorry, it's in French...

Thank, gonna give it a try, may be usefull for my animations.
