Just use the Chain SOP and provide a straight line as the curve input, it'll handle it for you.

I don't think you'll likely see a huge computational difference but you could totally benchmark it if you want. A Transform in SOPs context is multiplying every point by the matrix you define in that interface anyways... I wouldn't expect adding a fixed value to P every frame to change that too much.

If you're trying to do this in the most straightforward way possible, I wouldn't even bother with a For/Each loop. Just use the Chain SOP and provide a straight line as the curve input, it'll handle it for you. Just figured this example with VEX and loops would be a good way to show you how Houdini thinks and better answer your original question.

Hi !

I think the "match size" node could be usefull here...


Thanks. Seems like an elegant solution! I'll try to get it to work with an arbitrary number of input geos.
