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.

Hey Francesco,

have you tried using a lattice on all your lines to bend them?

Cheers

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
Francesco

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

Francesco

its mixing between its original point position and one flattened in Y (@P * {1,0,1}) using a gradient that runs from 1st to last point per line.
so not really ‘bending’, but looks the same.
