I'll take a look at that page about git. I'll also adapt the use of polyvox voxels. Just tell me what revision is considered stable, or perhaps I should wait until git is restructured, to begin.
David will have to give you more information but it's probably best to wait until the changes to voxel types are finished before changing your code to match.

For the integration I think it's still worth waiting until after we make a release of PolyVox, because until then I won't have the time to give it the thought it deserves. But once we have the seperate 'develop' branch I think you can usefully make sure that your code still works with the changes which have been made to PolyVox. This develop branch is supposed to always be compilable at least.

Mostly I just wanted to make sure that you were aware that we are moving forward and getting back to PolyVox (and let you know that the TVA stuff hasn't been forgotten), because the work on Voxeliens has taken longer than expected.

Hello,

Is this maintained, following Polyvox refactorings ?
I'm not sure because I tried both latest versions, and could not build polyvox-tva.

ex:
Code:
polyvox-tva/./include/tva/polyvox_utils.h:1359:5: error: ‘getThreshold’ is not a member of ‘demo_tva_traits_a::VoxelType {aka PolyVox::MaterialDensityPair<unsigned int, 16u, 16u>}’


Maybe it is easy to adapt myself ? Or would I better wait for a stable Polyvox release before adapting ?

Thanks

No, it has not been updated since the re-factoring. It is in fact waiting for a stabler Polyvox to be adapted.

If David gives me the go-ahead, I'll bring it up to date.

Ok thanks for the info. So I'm impatiently waiting for this new Polyvox release :)

By the way, I had to force flag -std=c++0x in order to get that far in the compilation. I don't know if things with Ogre would have compiled with this (I saw other people having problems in the forum with Ogre and c++0x). I guess if we can't mix, the detection of the c++0x features could be improved in the Polyvox makefiles.

Yeah... the release takes forever :-( Basically I've just got too much going on at the moment, combined with the fact that tidying/refactoring/documenting code takes much longer than writing it in the first place. There's still a steady stream of commits taking place though so progress is being made.

Maybe I should do a blog post to provide some insight into the current state of things...

Is it related to different version of polyvox or what?

At least some of these are related to the PolyVox version (for example references to 'getThreshold'). You might want to try getting an older version of PolyVox by looking at the dates on the posts in this thread.

i tried with all the previuos release but the best result i had with polyvox version 'PolyVox-GIT-2e4bf67' from download page. But still i got this error regarding boost:

and i saw in the readme file this:
Quote:
General Notes:
* Define POLYVOX_TVA_INLINE to "inline" or to a compiler specific macro/attribute/pragma that can take
the place of "inline", such as "__forceinline" (msvc), or "__attribute__((always_inline)) inline" (gcc,
be sure to escape spaces and parentheses). The same can be done for the cube library, with CUBE_INLINE.
If they are not defined, they default to "inline".


but not really sure to understand.

in CmakeList.txt i uncommented the line:

Quote:
##FIXME
add_definitions(-DPOLYVOX_TVA_INLINE=__attribute__\(\(always_inline\)\)\ inline -DCUBE_INLINE=POLYVOX_TVA_INLINE)


but i got the same error...

also Cmake don't make automatic linking of the lib and include and i have to set manually (and i got same warnings)

maybe i don't set properly POLYVOX_LIB_LINK and OGRE_LIB_LINK maybe the error is related?
