Hi,
Okay...
I get indices like that:
_indices =
temp->asGroup()->getChild(0)->asGroup()->getChild(i)->asGeode()->getDrawable(0)->asGeometry()->getPrimitiveSet(0);
//temporary; data existence is checked; i know it's bad
and then
indices[i] = (int*)(*_indices).getDataPointer(); //copy to 2-dimensional array
by mesh index
Just to make sure you understand everything, some primitive sets include
an index list, and others don't. You'll need to be sure you're
accessing one of the DrawElements primitive sets to be able to get an
index list.
If you're sure your PrimitiveSet is a DrawElements, try this instead:
indices[i] = (*_indices)[i];
or
indices[i] = _indices->at(i);
The first version is a direct access (and might be slightly quicker),
and the second will do range checking and will throw an exception if you
try to access something outside the bounds of the list. The
DrawElements class itself is a descendant of std::vector, so you can
just access it using the standard vector methods. You don't need to go
all the way down to the data pointer.
