bend a line or stick

[Tong Le]

Hi there,

I know this is a simple question, but I still dont know how to do it.

I just wondering is there an easy way to bend a line procedurally(very simple like the attachment)? Like you guys did in helical cable challenge.

Thanks,

Tong Le

you could do it with exppressions but it would be a crazy long expression,

there is a couple of bend assets on the exchange that works a little differently to the native bend, and more like the max bend.

The base of a line or tube will not move when the object is bent - the pivot is at the base.

look for 'rk omni bend'

its a good exercise to make your own in VOPS if your into that sort of thing...

Nah, it just two short lines in pointSOP:

$TX * cos($BBY*ch("bend")) - $TY* sin($BBY*ch("bend"))

$TX * sin($BBY*ch("bend")) + $TY* cos($BBY*ch("bend"))

youre right - not so long - good use of expressions

 

but why is it that the opposite sides of the tube seem to bend differently ?

possibly because the bend applies differently to points that are different distances from the origin
