Evenly spaced instance shape on curve. [Solved]

Post by Maximus » 18 Jul 2012, 05:44

Hey guys, i'm tryin to solve an apparent simple problem.
I was lookin for a tool to create evenyl spaced instances on curves and profiles, so to create those precise patterns, like you see on jewels or rings or whatever.
I tried first the duplicate command and then the constrain to path with the L(100) value.
The problem is i cant get the orientation i want.

I've extracted a curve from the torus.
I've setup a simple scene to illustrate what i want to do, basically i found on the net some compounds to achieve an evenly spaced instanced geometry which is fine, i'm still struggling on how to get the orientation in a correct way.
I think the compound i've found is from Julian Johnson if i'm not wrong. anyway here is an image:

They are all pointing upward, but i want them to lets say roll on themselves and point outward evenly.

I dont know how to explain...basically the base of the cone should be sitting around the normal of the torus, producing like a ring with all the cones sitting evenly and pointing outwards.
How can i orient those in that way? Because if i move the angle or the orientation axis they all move together but they dont "open" outwards.

god i hope i made myself clear :)

Here is the compound i'm using in case someone wants to try-

Anyone knows a way to do this? or is there already a compound or addon to do this kind of task?

Thanks, Max

Ok sorry but after i wrote the post i fixed it by myself...

i used the nodes inside the align to position and i just got what i wanted..

here is the updated compound

Hi there,
I Downloaded the compound, but it seems things are either deconnected or missing inside the compound (2013 here). Is it possible for you either to save a scene or a model, or maybe a screengrab ?

Cheers,

Olivier

I think you need to get the Evenly Spaced Curve Positions compound.
