Hi Francesco,
just tried it with a current OpenSG version and it worked fine. I think
I fixed some time ago a bug in calcVertexTangents() what version are you
using.
Andreas
I just upgraded to a CVS version compiled yesterday... it still crashes!
maybe it's an error in my code...
In attachment there is a sample program i wrote to test
calcVertexTangents() functionality... and it crashes to me with
dinosauro.3DS. What's wrong ?
thank you very much for your time ;)

#define MODEL "C:/Documents and Settings/tamagni/Documenti/dinosauro.3DS"
int main(int argc, char **argv)
{
// OSG init
osgInit(argc,argv);
printf("loading model...\n");
NodePtr model = osg::SceneFileHandler::the().read(MODEL);
printf("done.\n\n");
if (model != NullFC){
// i know that the problematic model has ony one level of
children
for (int i = 0; i< model->getNChildren(); i++) {
NodePtr child = model->getChild(i);
if(child->getCore()->getType().isDerivedFrom(
Geometry::getClassType())) {
GeometryPtr geo =
GeometryPtr::dcast(child->getCore());
printf("calculating TBN...\n");
calcVertexTangents(geo, 0,
Geometry::TexCoords1FieldId, Geometry::TexCoords2FieldId);
printf("...DONE!\n");
}
}
}
