Playing around with CTreeContainer and the script you provided here 
http://www.gamedev.net/topic/643968-procedural-terrainworld/.

(Disclaimer: Not sure how useful the following discoveries actually are, since 
I still suspect an MSVC 2010 incompatibility. Again. It does look like your 
above script works with your compiler.)

Had some time to realize that CTreeContainer::getRGBABufferUnsafe wasn't 
actually covered by the lua binding (Maybe there's some other way to grab it). 
Adding it to Builder.pkg was easy enough.

So far so good, but no matter what, I always got pitch black. Another debug 
session made me realize that something was off with the overloads in 
scaleOffset. Other overloads failed as well, especially rgbaCompositeChannels: 
Breakpoints revealed that the fixed 1.0 alpha came out as "1", so the tree 
container looked for an nonexisting node (and returned zero). So I landed in 
the lua interpreter code and almost gave up.

Then I found this (paragraph Overloads)
http://www.codenix.com/~tolua/tolua++.html#functions

Quote: "It is important to know that tolua decides which function will be 
called in run-time, trying to match each provided function. tolua first tries 
to call the last specified function; if it fails, tolua then tries the previous 
one."

Ah-ha. The "fix" was to reverse the order of the overloads. Quoted since I bet 
there are now other combinations which will fail. To really fix this means 
probably to use a different approach, I don't know (as mentioned on gamedev, I 
have no experience with lua ).

Or am I missing something ?

Nonetheless, I attached the script and Builder.pkg.

Cheers.

Full error:

error C2552: 'dirs' : non-aggregates cannot be initialized with initializer 
list ..\accidental-noise-library\Imaging\erosion.cpp line 28

Here's the MSDN entry : 
http://msdn.microsoft.com/en-us/library/0s6730bb(v=vs.90).aspx

Using the constructor explicitly works:

    static SDrop dirs[8]=
    {
        SDrop(-1,-1),
        SDrop(0,-1),
        SDrop(1,-1),
        SDrop(-1,0),
        SDrop(1,0),
        SDrop(-1,1),
        SDrop(0,1),
        SDrop(1,1)
    };


I tried to do a commit, but I would probably need permission for that.

Cheers

Hi,

How does someone use that function? I see lots of overloaded definitions in the 
headers.


Thanks
