export hair as curves?

export hair as curves?

is this / will this be do-able in 2.5?

i’m looking for an app to comb hair in and then export as curves into houdini to use as guide curves for instancing…

thanks :slight_smile:

This is unrelated to 2.5 development, and how would you propose to export them?

they’d need to be converted to polygons, or lines, whatever you wanna call them
with verts

then exported as an OBJ would be fine

Wouldn’t collada support curves data?

even if it isn’t in scope for 2.5…

doing a quick full pdf wide search in collada 1.5 spec pdf for curve definitely gets lots of hit’s…

423 hits, amongst them splines beziers and fcurves seem to be separately listed there…

just a quick glance though…

good point felix… maybe the new gsoc collada module would help?

although i’m a big fan of collada, most of the guys in my facility aren’t really…
so a simple OBJ export would be fine… if hair can be converted to poly’s

You could convert the particles into a mesh, then the mesh into poly curves (mesh menu as a script), tell the polyline to be nurbs, then export the curves as OBJ/Nurbs which I added for 2.49.
Even though this sounds complicated you can do all the curves at once for each step so its not that bad.

thanks, i think i’ll be waiting for the 2.5 release before i actually start testing this out…

pipeline integration-wise, 2.5 is going to be a treat :smiley:

was just wondering if it’s possible, which i see it clearly is!
