Hi,
I need a little help with this. I thought I was getting it, but it just doesn't seem to be working. I'm missing something with translating the points back to where they need to go. The object moves to the bounding box center correctly.
Matrix Mg = obj->GetMg();
Vector globalPos = Mg.off;
Vector bbLocal = obj->GetMp();
Vector bbGlobal = bbLocal * Mg;
//Move object to Bounding Box center
Matrix newObjMg = Mg; newObjMg.off = bbGlobal;
obj->SetMg(newObjMg , TRUE);
//Move Points
Vector trans = bbGlobal - globalPos;
PointObject* pointObj = ToPoint(obj);
if(!pointObj) return FALSE;
LONG pointCount = pointObj->GetPointCount();
if(pointCount == 0) return FALSE;
AutoAlloc<Modeling> mod;
if (!mod || !mod->InitObject(pointObj)) return FALSE;
LONG i = 0;
while(i < pointCount)
{
Vector pointPos;
Vector* pPointPos = &pointPos;
mod->GetPoint(obj, i, pPointPos);
Vector newPointPos = pointPos - trans;
mod->SetPoint(obj, i, newPointPos, MODELING_SETPOINT_FLAG_EMPTY);
i++;
}
if (!mod->Commit()) return FALSE;
