Thanks , that makes things a little clearer.
As for the random pattern i was thinking if you
have multiple height maps, that it would ‘chunk’ seamless tile
them in a random order, for really big random terrains.
Then you can have preassigned compatible xyz locations,
for objects, for each of the different height maps.
I don’t really know what I’m talking about, as I haven’t
tried the heightmap system yet, and this is probably already implemented.
Mainly i was interested in your three point camera system,
and I should have asked you about that! I spent about two hours
trying to pull it apart yesterday, 
<<too much looking at code eyes.
Thanks for the explanations, I’m going to try it again,
I loaded my panda with PYPE and I’m constantly cursing it
because i think thats why half the demos I try don’t work.
