Maya Fluid to Houdini

[holofernes]

Hi!

I'm recently working on a plugin for exporting Maya fluid's voxel to Houdini. I got up to a point where it's too slow. I get all sorts of informations out of Maya, density, color, velocity, but it gets slow when I read them in Houdini. The reason is because I'm doing everything through .chan files, where I read and transfer all the attributes to points. I was thinking of exporting everything from maya as a .sim file.

Now,

this is a problem, cause I have no idea where to find the sim structure data. Any help?

Also,

would it be possible for me to use any of the HOM modules to write a bgeo format?

Thanks,

Fabio/

This can be a starting point.

Volume primitive support isn't in there but I've heard of at least one person successfully adding such support into their own branch of GPD.

PS. There's a text file in there that describes the format in glory detail

On a similar note, I wonder if there is value in writing direct support for Imageworks' recently open-sourced Field3D format? Does anyone have any opinion about this? An open-source format might be a lot more convenient to support than a closed format like BGEO, especially if one is sharing fields between applications.

I used to export maya fluid sims when I was at Imageworks using their 'pre-Field3d' format called .istor, I left before Field3d was implemented, but if the functionality was there for .istor, should be just as doable with field3d as well ?
