From Lars Nilsson, "Attached is a small program doing intersection calculations, both with and without KdTree. The geometry is a TRIANGLE_STRIP consisting of five vertices, all with the same rather high Z-value. If the intersection calculation uses KdTree, it fails. When I changed osg::Vec3 to osg::Vec3d in a few places in osg::KdTree it finds the correct intersection point."
...
From Robert Osfield, I didn't merge the change of parameter type of IntersectKdTree::intersect() as the internal maths is all done in Vec3s. Keeping Vec3 here hasn't effected the test results.
