  1. hi just learn houdini particle. i am a beginner in this project i use particles points then use copy to points node , boxs to make up model. like this picture however the problem is i find some box jitter very unacceptable so i Calculate the points distance between previous frame in solver node if the distance less than 0.05,then the point do not move this way make the points jitter less however i need calculate the angle distance between previous frame also but i do not know how to calculate the rotation difference let`s say ,if the rotation difference less then 0.1,then the point do not rotate. bellow is the project file point_jitter.hip thanks for your help
