[Insight-developers] mesh data structure problem.

[Luis Ibanez]

Hi Ting,

my mistake, I should have said:

    point.Value() = p;

for the iterator,
intead of :
 
     point.Value( p )

In any case, that will only help you
with the speed of access.

I think that the real problem in you
code could be the allocation.  
Did you add a line like:

   GetPoints()->Reserve( 1000 );

before starting to get access to the 
points ?

This line will allocate a number of 
points (1000 in this case ) for you.


Hope that helps,

Luis
