dtcs 0 Posted June 21, 2021 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 Share this post Link to post Share on other sites
crispr_boi 5 Posted May 2 I still don't understand how to create growth, that is limited to or mostly adheres to growing into two directions. Like variant #8 and #9 in the video "a unified approach to grown structures" https://www.youtube.com/watch?v=9HI8FerKr6Q Changing the frequencies and amplitudes of the volume noise, doesn't seem to achieve this result.
