Ok, I found the problem and it was just a stupid mistake on my part.
I was passing the complete path of the .otd file to Manta instead of just the filebase (i.e. the path minus the .otd file extension). Hence, Manta was unable to read my generated octree data file and created an empty data structure resulting in a segv when this was raytraced.

DOH! Well, at least this has familiarised me with the code :)

Manta now appears to render the octree data as the debugger now shows the data to be populated. However, although the FPS are displayed nothing is actually visible in the render window? Do you have any idea why?

FYI, I've included a screenshot and links to the data files I'm using here:

That's the basic point-location lookup routine for a node. Usually when this fails, it's because the data isn't built correctly.
