display bones in skeleton

[AndyBeaulieu]

Hello,

 

I am trying to create a visual representation of the bones contained in a skeleton, by using a bunch of simple Box Meshes.

 

I am able to show the position of the bones using the _worldTransform.m[12], [13], and [14] as shown below.

var absPos = new BABYLON.Vector3(bone._worldTransform.m[12], bone._worldTransform.m[13], bone._worldTransform.m[14]);boxMesh.position = absPos;

But now I would like to scale and rotate the boxes so that they visually represent the bones in a skeleton.

 

How can I get the scale and rotation of each bone in this case?

 

Thanks!

Hi, 

 

A bone is just a a point (joint). If you want to retrieve the bone's scale, you have to get the distance between a bone and his parent.  Same thing for the orientation you can try bone LookAt his parent.

 

Hope this help.
