get all the available point attributes?

[Linghaoli]

Hi guys:

 

  To get a point attribute's info, normally it's going to be like the following:

gdp->findAttribute(GA_ATTRIB_POINT, attr_name);

Is there an similar method to do something like:

gdp->findAllAttribute(GA_ATTRIB_POINT);

?

 

If not, what's the best way to list all the available point attributes on a point in hdk?

 

thanks a lot!

 

(I tried going through the old posts roughly, but seems there is no answer for this yet. Apologize in advance if I missed it )

Untested code

for (GA_AttributeDict::iterator it = gdp->getAttribDict(GA_ATTRIB_POINT).begin(GA_SCOPE_PUBLIC); !it.atEnd(); ++it)
{
    const GA_Attribute *attrib = it->attrib();
    std::cerr << attrib->getName() << "\n";
}

thanks for the reply edward.

 

it kinda worked:

    for (GA_AttributeDict::iterator it = gdp->getAttributeDict(GA_ATTRIB_POINT).begin(GA_SCOPE_PUBLIC); !it.atEnd(); ++it)
        {
        const GA_Attribute *attrib = it.attrib();
        cout << "Point attr: " <<attrib->getName() << endl;
        }

but it seems not getting all the point attributes?

In my test case, there are a few points scattered from a cube, and then I added a custom attrib named 'id', which is the same as $PT.

 

So ideally it should print out "P" AND "id", however, it only prints out "P" with the above code.. any idea would be really appreciated.

I am in hdk 12 if this makes any difference.

 

 

thanks

If it prints out P, then it should definitely print out id, are you sure that you're running it on the node that actually has id added?

found the issue, I forgot to duplicate the input..

    duplicateSource(0, context);

after that all good.

 

thanks again edward!
