Hi Foamers,

I'm trying to do some simple shadowing in openFOAM using ray-casting. Obviously, I'd rather use the built in octree classes to speed this process up rather than doing a brute force check of every patch face against the points I want to get shading data for. To this end I tried to impliment the octreeLine class with it's getIntersections() method, (http://foam.sourceforge.net/doc/Doxy...ctreeLine.html) to get a list of the cells intersected by a given line.

I followed the exact same setup as shown on octreeLine's Doxygen page but whenever I compile I get all kinds of errors that look like they reside in the base OF code. (See attachment for the output)

Has anyone successfully used this method or is this a bug in the code? Thanks!
