Hi,
I tried to copy from the STL loader but in my case it crashes
somewhere in createSharedIndex. So I took a closer look at the
STL loader. Here's a snippet:
beginEditCP(points);
beginEditCP(norms);
while (actIt != endIt)
{
points->addValue(Pnt3f(actIt->v1x, actIt->v1y, actIt->v1z));
points->addValue(Pnt3f(actIt->v2x, actIt->v2y, actIt->v2z));
points->addValue(Pnt3f(actIt->v3x, actIt->v3y, actIt->v3z));
norms->addValue(Vec3f(actIt->nx, actIt->ny, actIt->nz));
++actIt;
}
endEditCP(norms);
endEditCP(points);
beginEditCP(geo);
{
geo->setTypes (type);
geo->setLengths (lens);
geo->setPositions(points);
geo->setNormals (norms);
}
endEditCP(geo);
createSharedIndex(geo);
calcVertexNormals(geo);
As you can see there is one normal per face. But shouldn't it be
one normal per vertex? Is this code correct? If I remove the
"setNormals" call my program does not crash anymore, perhaps
the createSharedIndex routine trys to access the normals array
outside of its boundaries...

Toni
