So this will either require some math (Line/Line intersections) but it would be harder for doing it with a curve of a degree higher than 1. Though I remembered maya had a split by curve tool so I had a quick look for you.
The steps are to "project the curve" onto the mesh and then "split the mesh by projected curve". This creates a *polyProjectCurve *node and a *polySplit *node. The interesting bit here is that the PolySplit node "splits" based on a predefined set of information for where to split. As such this information must be provided (in some way) by the polyProjectCurve node for it to work. Next step would be to investigate a bit into what's connected between the two nodes, where the critical information is in the curvePoints compound attributes. There it's stored as a set of "split points" that represent the "face id", "triangle id" and the "barycentric coordinate". Unfortunately there doesn't seem to be information on the node that just gives an "edge id" and a percentage along that edge... but it might get you closer? Just thought I'd share this to see if it helps in any way. It's not necessarily trivial to go from there, but it shouldn't be impossible either. The nice thing by using the project curve method it allows you to do it using any degree of curve and all of the functionality Maya provides along with it. Node that the polySplit will always create a vertex on the edge, but might also create more... maybe there's a way to set it up so it only creates points on the edges or query that easily, but I didn't investigate that further. Hope it helps. On Monday, January 18, 2016 at 6:05:24 PM UTC+1, Dilen Shah wrote: > > Thanks for the reply but i am looking for something in Maya.
