[osg-users] Line tessellation with osgUtil::Tessellator

[Glenn Waldron]

Valerian,

I recommend you look into the osgUtil::PlaneIntersector. For each segment
of your line, construct a plane that is orthogonal to the grid. The
PlaneIntersector will generate a Polyline containing all the points in that
plane that intersect the grid.
