jit.freenect.grab on 64 bit?

Hi Karl,

I've just updated the old project to the max6 sdk, and compiled a 64+32bit external.
It loads fine in both 32bit and 64bit flavors of max, but at the moment I don't have a kinect here to test and don't know if it actually works.

It'd be great if you'd have a moment to give it a try.
In case it doesn't load, please copypaste the contents of the max window so I can see what's going on.
In case it loads but doesn't work properly please try to describe what's happening.

Hope you'll have some fun with it!

Cheers,
nesa

hey,
i'm a little bit in a hurry but this is tremendously cool you are at this! thank you so much!!!
i tried to load it into max running at 32 bit and 64 bit but it doesn't load yet, see the output of the max window below (i think the error message is the same for both versions).

p.s. the error does not occur on load but as soon as you make an instance of jit.freenect.grab and this instance is as well beige (like it is with nonexisting commands)

Aha, thanks for the report, it's my bad - the external is not statically linked to libfreenect so it would only work if you have it preinstalled.
I'll look into it tomorrow, but if you need it urgently and don't mind compiling you can follow the install instructions at:
https://github.com/OpenKinect/libfreenect

Allright, here's the statically linked version, it works on both 32/64 bit versions. This is the last version in the main branch, one by Jean-Marc and it still has some quirks.

I've been working on this external now and then, with bugfixes and some new features - I hope to polish it up in the following few weeks and release it, so check this space for updates:)

Thanks for testing!
nesa

I basically duplicated your efforts, but here's a git repo with the same thing. This is a 64-bit-only build.
see the release page for .mxo download:https://github.com/brianchasalow/jit.freenect.grab-64-bit/releases
or the git page for src:https://github.com/brianchasalow/jit.freenect.grab-64-bit

hi derp and nesa,
I noticed that nesa's version has a @aligndepth attribute which is very useful --

@nesa, do you have the source for your version on github somewhere?
and/or @derp, do you have plans to add the @aligndepth attribute in your version?

thank you both for your work on this!
cheers,
rama

Hi Rama,

I was one of the original developers of the jit.freenect.grab, and you can always find the sources on my github fork:

https://github.com/npnp/jit.freenect.grab

Derp's version was cool, but it is only 64bit - mine is universal.

The initial version of the project was a hacky mess, hell to compile. This one should be much easier.

All the paths are set through .xcconfig - nothing should be changed in the project settings directly. The xcode project is a modified example from max sdk, and I removed all the unnecessary references to libusb/libfreenect sources in the project itself.

the configuration file expects to have the libusb and libfreenect one folder up from the jit.freenect.grab source, but it's easy to edit this to fit different setup.
libusb and libfreenect also have to be compiled as both 32 and 64 bit as well. Let me know if you need some help on setting this up(by default they compile for one architecture as far as I remember).

the external is (should at least) build with statically linked version of libfreenect and it should be self-contained.

32 and 64 bit, max 6 and 7 tested.

alighdepth is there as well.

I've attached the bare compiled external as well, but some work has to be done on helpfile and maybe packaging it properly - hope someone would be up to help with that?

Rama, please let me know if you run into any issues with compiling and running, I'm really eager to fix the project properly so we can concentrate on the bugs&features.

Best wishes,
nesa

hi nesa,
thanks! this looks great -- and with cleaner library linking than the other version I was looking at. I'll see if I can compile it sometime soon, and let you know how it goes. I can take a look at the help patch etc. also.

very happy to hear the project is still active!
cheers,
rama
