Re: [osg-users] 2Dimensional array

2008-11-20 Thread christophe loustaunau 
there is little mistake with this :
osg::ref_ptr currentDataArray;

it should be :
osg::ref_ptr currentDataArray = new osg::Vec3Array;

With this it should work.

Regards.

Re: [osg-users] 2Dimensional array

2008-11-20 Thread Ed 

So I could do something like this (in pseudocode)?

   std::vector< osg::ref_ptr > myData;   


   osg::Vec3f currentDataPoint;
   Outerloop...{
   osg::ref_ptr currentDataArray;
   Innerloop {
   currentDataPoint.set(...);
   currentDataArray->push_back(currentDataPoint);
   }
   myData.push_back(currentDataArray);
   }

 Is there such a class?

Hi Ed,

Maybe you could use  std::vector myArray .

Re: [osg-users] 2Dimensional array

2008-11-20 Thread Dusten Sobotta 
Why not use vectors?  std::vector< std::vector< osg::Vec3f > > vec3array;

or ideally, for instantiation/allocation efficiency, std::vector<
std::vector< *osg::Vec3f > >

[osg-users] 2Dimensional array

2008-11-20 Thread Ed 

I need to create a 2Dimensional array of Vec3f.  I could do this the ol'

osg::Vec3f **myArray

way, but wasn't sure if that is the way it "should" be done, as opposed 
to osg::ref_ptr, etc.   The I thought, maybe there is already a class 
for 2Dimensional arrays...but I didn't find one.  Is there such a class?
