Windows support
Does Partio currently support windows? Has anyone made a fork or any patches to get partio to compile for Windows?
Thanks!
Tony
I have compiled and briefly tested Windows compilation around release time. I have not built or tested the python components. Are you having trouble?
I edited the scons file to work with msvs. I got it to compile, but the tests fail. A few others ran the tests on Linux and also their results failed. Are the tests broken? Thanks!

Ah.. the windows support was done with respect to the CMake build files, so it's nice to have them working with visual studio too. which tests are failing for you?
$ ./test.exe Testing with file 'test.bgeo' Testing with file 'test.bgeo.gz' Testing with file 'test.geo' Testing with file 'test.geo.gz' Testing with file 'test.ptc' Partio: failed to find attr 'normal' for PTC output, using 0,0,0 Partio: failed to find attr 'radius' for PTC output, using 1 Partio: Unable to write data type FLOAT[2] to a ptc file Partio: Unable to write data type INT[1] to a ptc file Testing with file 'test.ptc.gz' Partio: failed to find attr 'normal' for PTC output, using 0,0,0 Partio: failed to find attr 'radius' for PTC output, using 1 Partio: Unable to write data type FLOAT[2] to a ptc file Partio: Unable to write data type INT[1] to a ptc file Testing with file 'test.pdb' Testing with file 'test.pdb.gz'

This one I get an Assertion Fail something to do with vector. I get a vector subscript out of range.
Thanks!

I m on Win X64 & here is link (http://forums.cgsociety.org/showthread.php?p=6826936#post6826936),where you can get partio tool which i compiled on Win X64 using MS VC++ 2010 express with the help of Win7.1SDK.Hope this will help.Enjoy
do you have the build stuff in a fork somewhere so I can build it myself? Just wondering :). Thanks for your hard work!!!
Yeah, I'm happy to integrate the changes to make windows work again into the mainline. When I tested windows, I did with with the cmake build method.
Hello!
I recently tried to load partio tools with partview, and I'm getting the same "doesn't match bgeo magic '1114072431" error; I thought it might be related to Houdini 12 (that's where I'm generating the bgeo from), but apparently its not? I'll keep digging, just wanted to chime in.
Thanks!
You are correct, the issue is with Houdini 12. They have changed the GEO/BGEO format to a JSON/BJSON file format which the current version of Partio doesn't support. In the short-term you can use the gconvert command-line utility to convert from the newer formats to the old.
I'm in the process of writing a new reader that can handle it and as long as my company allows me to upload the results when it's complete I'll post the changes.
I am also in the process of writing such a reader. I can push my current state on that if you want to compare notes.

That would be useful. I'm not sure my changes will be suitable for the main branch at this point since it's using the Houdini UT_JSONParser classes since I didn't have time to sort out their tokens for their BJSON stream. I imagine people will want to be able to build partio without having to link against the Houdini libraries.
At this point I have successfully pulled out all the values for both the new GEO and BGEO files, just figuring out how to generate the appropriate ParticleAttributes and ParticleAccessors in partio.
We just ran into the Houdini 12 format change here at Imageworks -- @aselle do you have a patch we could take a look at?
I can post what I have. I haven't really gotten around to finishing it off or packaging it as an importer. I hope to get around to finishing it next week. A temporary workaround is to write to .bhclassic which will make the old format. Then you can register a reader for that in partio in the io.cpp I believe.

Good to know. There's no rush - the workflow of using gconvert is fine for us too.
