Vertex skinning

JayJay · 08-18-2011 02:49 PM

Model B is a copy of model A except that some vertices were slightly moved to a nother position (but no face, edge or vertex was deleted or added). A skeleton was added to model A using the model editor.

Is it possible to map the vertex skinning of model A to model B?
How is the vertex-skinning-data stored? Can I access the vertex-skinning-data in C++?

Thanks in advance!

no

yes, check meshbase headers

Thank you Esenthel.

If someone wants to do something like this:
The easiest way in C++ to copy all data from model A to model B except vtx-positions (or what ever):
1) create a copy C of mesh A
2) replace the vtx-positions (or what ever you want) of C with the ones of B

PHP Code:

for (int j = 0; j < to->parts.elms() && j < from->parts.elms(); j++)
{
    for (int k = 0; k < to->parts[j].base.vtxs() && k < from->parts[j].base.vtxs(); k++)
    {
        // copy the position
        to->parts[j].base.vtx.pos(k) = from->parts[j].base.vtx.pos(k);
    }
      // recalculate vertex normals
    to->parts[j].base.setNormals();
} 

3) replace B with C

It's that easy. Note that this just works if model B is a copy of model A except that some vertices were slightly moved to a nother position.
