Hey,

I’m exporting a model from the scene and it looks like the data i get from it isn’t transformed liek I see it in XSI.

XSI::Primitive prim = xobj.GetActivePrimitive();
XSI::PolygonMesh mesh = prim.GetGeometry();
XSI::CGeometryAccessor ga = mesh.GetGeometryAccessor( SI::siConstructionModeAnimation, XSI::siCatmullClark, 0 );

With the geometry accessor, I extract vertex positions, normals, UVs etc. If I call GetTransform on the GA, I get the local ones but still not the fully transformed one compared to what’s written in the parent view of the model.

Any ideas…

thanks!

You have to apply the transformation of the node on each positions, normals ....

X3DObject x3d;
CTransformation trans = x3d.GetKinematics().GetGlobal().GetTransform();
CVector3 outVect;
vect.MulByTransformation(position, trans);
With position, a CVector3 of the position of a vertex for example ...
