How to use VOP attribute to make point's normal of a curve point inward a "close" curve, half of the angle between the two segments.
that's so amazing. thanks for sharing with us.
Not sure what Houdini version you used for this recording, but thankfully now there is an "Orientation Along Curve" SOP which saves us from this math horror! 😂
Would love to see more like this in vex. Great stuff!
I will see if I can make an version of it in vex! thanks
Nice way to do it! thanks. How about PolyFrame/BitangentName/N (makeFrameOrthogonal) ? or N and invert it.
I may be doning something wrong, but I didn't get quite right angles doing this way. they are slightly off.
@@Terranimator Set style to 'first edge' as well
what a terrible tutorial!
It completly not working for me from the start.
If i use the Geometry fromVopOutput on the first 2 set of normalizes it points verry in a weird angle and not tangentional like with your example.
Fantastico. Top one
Thank you! Great explanation, worth the time. Thanks
Glad you enjoyed it!
Out of curiosity, do you still get perfect bisectiles angled normals if you don't use a resample node? I'm wondering if, without it segments of diff. lengths between "corners" will not require more adjustment with this set up to get the desired result. In any case, while I'm a bit more fluent with vex wrangles than with vops , I will definitely try this. Thanks for the contribution!
Great example of using dot and cross products!
Thanks! It helps me a lot !
the first part of the VOP i couldnt make it work (In my case i had more intricare curve), the normal of the point 0 was always messed up, so i used a polyframe SOP to get the orientation of the normal right. like in this tutorial ua-cam.com/video/sIL2sq73TIA/v-deo.html&ab_channel=SergeyGolubev
Having difficulties at ua-cam.com/video/WHdhdx1zGDk/v-deo.html and i can't get any Cross values to Negative.
They all are at 0. It seems i missed something.
using Houd 18.0.566 i have weird angle at both extremity points also.
Btw, thanks for sharing.
i think we had the same problem, try to watch this ua-cam.com/video/sIL2sq73TIA/v-deo.html&ab_channel=SergeyGolubev
