how to get and set the attribute value of a certain point?

Recommended Posts

One more question, what if I don't know the attribute type in advance? For example, I could only use the getType() to get the type, but I don't know if it's float or int.

I can't use

*(gdp->points()(4)->castAttribData<myType> (fooOffset)) = 27;

Could anyone here let me know how to handle the type information?

The problem is that you're allowed to have attributes of the same name but different types, so you may want to just search for them.

UT_String attrName;
for(GB_Attribute* attr = gdp->pointAttribs().getHead(); attr; attr = dynamic_cast<GB_Attribute*>(attr->next()))
   if(attr->getName() == attrName)
       const int thisOffset = gdp->findPointAttrib(attr);
