The namespace Intersection seems to be used in CuttingPlane, Cube and some other areas but I don't see any obvious name conflicts if the namespace was just removed and if it compiles without it then it is probably unnecessary. It could also be renamed to Intersections to match the folder name where that namespace code is located. I'll forward this to the Manta mailing list if anyone still reads it and had a reason for the namespace.

I'd vote for removing the Intersection namespace.

The Intersection class name refers to the CSG operation on two objects.

I was able to successfully remove the namespace from my local copy without any collateral damage.. I can commit if it sounds agreeable.

Hi all,

I've looked at this more, and it appears that this should be breaking everywhere... To the best I can determine, Jim's compiler is just the only one that is flagging it... It is possible that many compilers are not complaining because "Intersection" (the class) is (appears to) actually not used. I was able to fix the immediate problem for Jim by commenting out #include <Model/MiscObjects/ Intersection.h> from volumeTest.cc. However, I think that either Intersection.h should be removed altogether, or that the "Intersection" namespace should be renamed (perhaps to IntersectionNS or some such). Carson and Abe, please let me know which solution you think is best.

 Thanks,

PS. Jim, you Manta build completed. You can run the simple test program from your build dir by typing bin/manta.

O.K.  What about the build error, is it related, or a code bug?

Thanks,

Hi Jim,

The problems with CMake being vague have already been reported... we want to create a script that takes care of all this for you.

Also under #4, this is vague as heck:

First you will need to set the TEEM library path. Press the down arrow until you get to the variable *FOUND_TEEM_BIN*. Set this to the location of your TEEM installation by pressing *enter* and entering the path, eg /usr/bin. Press *c* to configure. If you get errors about not finding TeemConfig.cmake (in older versions before Nov. 2008 it was called TEEMConfig.cmake), you can manually set this by pressing *t* and going down to the variable named *FOUND_TEEMCONFIG_CMAKE*.

WHAT do I set FOUND_TEEMCONFIG_CMAKE to? I used /usr/local, but I don't know if that is right. I got a makefile.

However, during make, I get:
