Hand model collision detection.

[rubberpimple]

Hi farshizzo,

I'd love to see the code for this. I'm trying to do collision detection between a hand model and specific child nodes of a parent object. Did I read somewhere that I can only do collision detection on nodes that are children of viz.WORLD?

Hi David,
Have you got the code of bone collision?
Thanks in advance.

Here's the thread that has a response to this question

I have tried with the following code; does not work

import viz

viz.go()

viz.add('tut_ground.wrl')
#Add the ground and an avatar.
avatar = viz.addAvatar( 'vcc_female.cfg' )
ball=viz.add('ball.wrl')
ball.setPosition(0,0.1,9)
ball.collideSphere()
ball.enable(viz.COLLIDE_NOTIFY)
walk=vizact.walkTo([0,0,8.99])
avatar.addAction(walk)
boneCollide = viz.addGroup()
boneCollide.collideBox([.5,.1,.5])
foot=avatar.getBone('Bip01 R Foot')
boneCollide.setPosition(foot.getPosition(viz.AVATAR_WORLD))
boneCollide.setQuat(foot.getQuat(viz.AVATAR_WORLD))
nodes = viz.phys.intersectNode(boneCollide)
for n in nodes:
    print 'bone collided with',n

If you want to have collisions with the avatar's foot I think the code that Farshizzo posted in this thread will help. In that example a collision box is linked to an avatar's hand.
