I got it!I use it quite often for group selections and alike, but never saw it used in function.
I have few more doubts i would like to ask your help for, if you don't mind.
Firstly, after animating the curves with a carve, i noticed that sometimes is not the curve that is reaching the other that has “already passed” to go over it(which is what i would expect), but the other way around.
Secondly, what if a third line happens to be intersecting in a point where two are already overlapped?How could that be offset to be on top of the previous two?
Thank you
Francesco

Hi Tamte,
your help is great as always! I studied the fixed hip and have a question:
I don't quite get what is the “!” doing it the xyzdist function?
Many Thanks

Hello everyone,
I have banging my head about the following set up: I have many curves overlapping each others and need to offset one of the two at the intersecting points like in the attached. I have tried both with pcfind and pcopen and succeded to find an array of points that represent the intersection areas. The problem now is how do i chose only one of the points in the ‘group’ and only offset that one in the y axes so to have one curve over the other?
Any other easier/faster method would be much appretiated. I also tried to get the intersection points from intersection analysys SOP but it deletes the original geometry and curvesect SOP only seems to work between 2 curves.
Thank you very much
Francesco

Thank you Mohanpugaz,
the blendign mode made the trick!Thank you very much! Now to develop this further, how could i feed this into a simulation in order to make multiple snakes interact with each others and overlap?
Thank you again

Hello everyone,
I am experimenting with wire deformer sop. I animated a line with a sine wave and deformed a snake geo with it. Now, the main problem i have is that there is a regular twitch (it can be seen better in wireframe mode ) that supposedly comes from the animation but i can't figure out how to eliminate it. Any ideas?
Many thanks
Francesco

Hello and sorry for the delay,
so basically I would like the black lines to be at a equal distance between each other but the curve stretches the uvs.
Thank you

Hello everyone ,
While trying to procedurally uv map a curve sweeped onto an other curve i have encountered this stretching problem.
AS you can see from the attached, the distortion of the curve stretches the uv making it not uniform.
I am resampling the curve based on its lenght before giving it the uv attribute based on arc lenght.
Thank you for helping!

Hello everyone,
i would like to be able to resample an arbitrary curve based on its lenght. After measuring its perimeter, i tryed to call this attribute from the resample in the ‘maximum segments’ parameter but it doen't pick it up. What am I doing wrong?
Many Thanks

Hey cpb,
this is great! Exaclty what i needed, but i'm not sure I am understanding what are you did inside the poitvop. I got that you are distorting the curves based on the uv coordinates but would you mind explaining to me the process? Thank you, i really appreciate your help

Hi CYTE,
Thank you for your reply. I thought about several way to do it but none of them would be procedural. I would like to to do it on a point or line basis, regardless of the gemetry that gives me the point to scatter. Vops maybe? I lack the knowledge in this sense.
Thanks

Hi there,
I am tring to bend a number of lines copied to points with no success.
I managed to orient them with the normals, but what I would also need is to bend them outwards as if the gravity of the top would make them.

Hello everyone,
I am currently working on a personal project and have decided to force myself to think and work proceduraly, even when is not necessarily needed sort to say. In the model that you see, I need to polybevel only the longitudinal edges and i was thinking that would be great to have groups coming out of the polywire. Anyway, how would you approach the grouping of edges proceduraly in this case? If there is a non VEX approach, i would be very grateful if you could also include a VEX based one!
Many Thanks
Francesco

Hi everyone,
I am trying to defomr a mesh with the lattice sop, if the static points happen to be only on one side of the bbx the lattice works easily.
The problem is that i need also to deform the mesh inbetween two different lines of static points (as you can see in the attached)and i was wondering how would you approach it with a standard bbx or if it could be possible to use a custom bbox made of a lowpoly version of the main object?
Thank you very much in advance
