sanostol Posted November 6, 2006 Share Posted November 6, 2006 Hi again, I want to add Points to a curve, one at the beginning and one at the end and both should be placed on the tangent of the curve ( at the start or the end). The add Sop allows adding a point at the end, but how can I inverse the curve to add another point at the other end. Stuck... Maybe You can give me some hints.

Martin I'm not sure if this is what you'd want, but perhaps using a Sort SOP and set it to reverse the order of the points would help?

sanostol Posted November 7, 2006 Author Share Posted November 7, 2006 perfect, thanks Quote Link to comment Share on other sites More sharing options...
Dries Posted November 13, 2006 Share Posted November 13, 2006 Interesting. I'd like to do sort of the same thing. I was wondering how to get the right coordinates of a point that would follow the tangent of a curve when using the add sop, procedurally.

edward Posted November 13, 2006 Share Posted November 13, 2006 This is an example of how to calculate the tangent: http://www.sidefx.com/exchange/info.php?fi...mp;versionid=90 After that, you can just take the last point's position and then add some scaled version of the tangent to get your new point position.

Dries Posted November 15, 2006 Share Posted November 15, 2006 Thanks from me too. Very useful Sop. This sop is a bit hidden on exchange maybe, I was looking in modelling section earlier. Quote Link to comment Share on other sites More sharing options...
