Centipedes in Houdini

2/5/2018

 
Now coming back with another fun experiment, this time procedural centipedes, i have to confess these ones are a little hard to watch, i feel a bit uncomfortable.

Similarly with the sentinels, i had to use some trails and make a curve out of them to deform the centipedes, but this time the trails are not made with the trajectory of particles, because i needed to make the body collide with the other centipedes, so this time a similar setup of the tentacles was used, several pieces joined together with some hard constraints, then the head will have a random movement and the other pieces will try to follow the piece above the chain.
​
Then i take a distance value to feed the motion of the legs, those are controlled with an ik that uses a clamped sin equation for vertical movement and a sort of "zig zag" equation for horizontal movement.
And finally i use the path deform to deform the centipedes with the curves from the rbd simulation.
