Going off this link about the MD5Mesh file format, I see a bone is represented as:
"[boneName]" [parentIndex] ( [xPos] [yPos] [zPos] ) ( [xOrient] [yOrient] [zOrient] )
Since xOrient,yOrient,zOrient make up an orientation quaternion and not a vector, I don't know how to illustrate them. I'm still trying to get a grasp of bones and mesh manipulation.
How is the following represented in file?:
- Two bones of a simple stick figure (origin as "a" & left(or right) leg as "b")
- groin of model is at origin with the head in the positive y-axis direction
- arm wing span goes across x-axis
- leg is facing down and 2 unit out on the x-axis from the origin
