  1. Differential curve growth

    Hey guys, I have been seeing all the posts on this topic. I'm trying to implement the same thing using an SOP solver using VEX. My approach is typical, I run a wrangle node over the points, where I calculate the average vector for each point to determine the position of the current point for the next iteration. After this wrangle node, I append a resample node which will resample the curve on each frame and this creates endless growth. So, instead of resampling on each frame, I would like to divide the curve when the distance between two consecutive points has reached some threshold value that I set before. I don't know how to make this division using vex. I have attached my file below. I just can't figure out how to add a point between those two consecutive points and change the point number in the right order. Line_growth_01.hipnc
  2. Hi Guys, I was trying to copy an object along multiple curves. I have attached few images that show how I get these curves. What happens at the end I'm getting some curves that have flipped winding orders, this eventually changes the tangent direction. Due to which when I use copy to points sop it flips my object. Kindly share your thoughts on fixing this issue.
