    Hello!

    Is it possible to retrieve the coordinates of the tip and the root of a bone with COFFEE?

    Thanks

    I found out that the coordinates of the root corresponds to the value retrieved from the GetPosition() function. Can someone tell me how to calc. the coordinates of the tip?

    Thanks

    Bones extend along the Z axis, so just get the length and go that distance along the Z axis:

        
        
        Matrix m = obj->GetMg(); // Or GetMl() for the local coordinates  
        Real length = obj->GetDataInstance()->GetReal(BONEOBJECT_LENGTH);  
        Vector tip = m.off + !m.v3 * length;

    (Come to think of it, perhaps that ! for normalization shouldn't be there. I haven't checked if a bone with deformed coordinates axes calculates its length with the normalized or unnormalized axes.)

    Thanks Mikael! Let me know if you have any info about the normalisation

    Hmm...

    //snippet

    var m = obj->GetMG();

    println(m.off); //creates a sytax error!!

    I think this member only exist in C++. Do you have an equivalent in COFFEE for me?

    Thanks

    In C.O.F.F.E.E. that would be m->GetV0() and m->GetV3(), ! would be vnorm().

    Normalization would be easy to find out. Just test it with a bone that you have scaled (using the animation tool, not the model tool) and see which one works. (The one with vnorm()/! or the one without.)
