Hi,
Wondering if anyone from the list can help me.
I have a 3x3 grid of tiles from a terrain database, my aim is to get an
outline representation of this 3x3 by just using lines to represent each
tile.
My solution is the following:
osg::BoundingBox bbox ;
bbox.expandBy(node->getBound());
vertices->push_back(bbox.corner(0));
vertices->push_back(bbox.corner(1));
vertices->push_back(bbox.corner(1));
vertices->push_back(bbox.corner(3));
vertices->push_back(bbox.corner(2));
vertices->push_back(bbox.corner(3));
vertices->push_back(bbox.corner(3));
vertices->push_back(bbox.corner(2));
vertices->push_back(bbox.corner(0));
vertices->push_back(bbox.corner(2));
My problem stems from the fact that the square is way to big. I believe
it stems from the fact I'm using BoundingSphere to calculate extents.Is
there an obvious solution to this problem - To get a square that is
precisely the dimensions of the terrain tile?
Thanks in Advance
Paul
