I’m presently fighting an animation I made that I would really like utilized to a number of fashions, all completely different, however from the identical vertices.
I have already got a customized gltf importer prepared however I would like to shine my exporter. Therefore the query.
The primary mannequin has been exported to gltf and is okay.
My query is: is there a easy, programmatic, solution to edit this GLTF file to put the bones of the subsequent mannequin at completely different areas (that I do know) to nonetheless profit from an accurate animation or not?
That might be simpler/sooner than handbook changes.
I performed with vertices place contained in the GLTF, however the result’s a distorted mannequin.
Tried to change the animation matrices immediately as properly: identical ugly consequence (that is simply an excerpt displaying that I push all ancestors after which begin from the foundation, all the way down to my bone of selection):
whereas ( 1 ){
chain.push_back( node_idx );
if ( armature[node_idx].dad or mum == CONDITION_STOP ){
break;
}
node_idx = armature[node_idx].dad or mum;
}
for ( auto curr = chain.rbegin(), curr_end = chain.rend(); curr != curr_end; ++curr ){
u32 node_idx = *curr;
// skipped: choose the best animation indices, then:
mat4 mmat_current = compose( translation, rotation, scale);
mat = multiply( mat, mmat_current );
// hold going with mat
}
Perhaps there’s something to attempt with the inversebindmatrix[i] however I actually need a pointer right here.
So, what are my choices please? What did I get improper?
Thanks,
Edit: image of the issue. The skeleton is identical measurement, regardless of the mannequin being completely different:
How on earth can I drag the bone to their 3D place (I do know the ultimate 3D place within the world world every bone ought to have) ?
I attempted to solely play with translation matrices: fail.
