ablionbear Posted April 3, 2017 Share Posted April 3, 2017 I want to get a curve with normals facing the direction as shown below. I did this curve with add, follow by an asset which is similar to carve. I tried with polyframe, it didn't give the result I wanted. What should I do to get the normal? Cheers.

Noobini Posted April 3, 2017 Share Posted April 3, 2017 just a noob having a go...so I read up on various posts...found that you can just rename the tangent from Polyframe (from tangent u to N)...but I thought..why not do it from the Resample...my attribvop is hardcoded with Y as the up vector...so might not be ideal...maybe a pro could point the way...

Iskander Posted April 3, 2017 Share Posted April 3, 2017 (edited) I am always newbie too.) But look at this example,may be will be helpful. normal_example.hipnc Edited April 3, 2017 by Iskander 1 Quote Link to comment Share on other sites More sharing options...
ablionbear Posted April 4, 2017 Author Share Posted April 4, 2017 Thanks, mates. It works for me. I didn't realize there's a tangent attribute on the resample. From Noobini case, I get the tangent and cross product with Y vector to get the perpendicular normals. Iskander's method is more on attributewrangle, I am not very sure how it works, if you may possibly explain it thanks. Cheers. Quote Link to comment Share on other sites More sharing options...
