export obj from jitter?

March 17, 2009 | 8:01 am

Ok, Im really happy with some of the forms Ive been generating in jitter. Im curious if its possible now to export them out so I can do high res renders of them? I looked into a basic obj document and it seems really simple, for example here is a basic cube right from the obj file opened in text edit:

# This file uses centimeters as units for non-parametric coordinates.

f 7/13/21 1/1/22 3/3/23 5/14/24

so has anyone come up with a solution already? or is there a way I can format this easily with coll or something like that? Im not entirely sure what the last values are and how to get them yet.

It looks like the first are obviously vertex,
vt is maybe texture map?
vn is normals,
s maybe smoothing, because I remember turning off smoothing in the export,
f is like which points are connected together??

Even easier, I exported from maya with no normals or any data other then just the bare bones what it needs to work:

f 2/2 8/11 6/12 4/4
f 7/13 1/1 3/3 5/14

so I guess Im just curious if I can save long lists of data out through coll like this? I would just use export from a matrix if it werent for those letters before the numbers that will need to be prepended. Ill do a quick experiment and see.

thank you so much, that was perfect. I think c74 should try to include this in the next distro if they don’t make a built in object that can do it. I was always confused by the fact that you could read a model and not save one, especially when the format is so simple. I mean shoot you can save a matrix and movie every which way, but no 3d data.

I might try to make a setup with this that will capture animated sequences. Im not sure how long they will be able to be, but then I figure with a simple mel script in maya I can make it show only the model group with the current frame number.

Cheers, and thanks again!

glad it was useful, not had much time to look at it. let us know how it goes…
