Hi; In Vellum , is it possible to change the shape of input geometry, over time? I have a line in my scene that grows (in length) over time, and I would like to use it in vellum-hair, but it seems that vellum just uses first frame. Thanks. -

Hi, magicians! I already broke my mind trying to solve a simple problem) I created a point infection system and for every point I copy the geometry so I want geometry to grow from every new point. It seems that I need to associate the pscale attribute with the time attribute, but the pscale grows constantly in time which is logical. In addition, all new points grow from the existing @Time value associated with the @pscale. So how can I make growing @pscale in every new point from zero and stop after few frame/time with little random pscale? Or I think it’s wrong and I need to change the approach. Maybe try to animate the uniformscale in the geometry itself through some expression? I would be grateful for any advice

Hi, I am a beginner level Houdini user and I am trying to accomplish an effect where I grow curves from source points on an object that are dynamic and respond to collisions/forces. An effect similar to this I found some really helpful things on cgwiki (here http://www.tokeru.com/cgwiki/index.php?title=HoudiniDops#Grow_trees_with_particles ) dealing with grains, but I can't figure out how to have my curves grow from my source points while remaining attached. Anyone know a way to accomplish this effect?

Hey! I was going through some tutorials on growth solvers, and I noticed that a lot of them are driven by the "food" group looking to get "infected" if you know what I mean. I wanted to try and make a growth solver that workes differently, looking instead at the points that are already infected and infecting more from their perspective. A very simple summation of what I'm trying to achieve: 1. List the points around me 2. If they are food, they are candidates 3. Infect only 1 of the found candidates rinse and repeat I've put the code underneath in a point wrangle in a solver, but it doesn't work well. I tried running the command on the seperate food and infected groups but that doesn't seem to improve either. What happens when it doesn't go well: 1. nothing 2. Almost every point gets put into the infected group in 1 framespan and then the solver doesn't do anything anymore. //initialiation of radius to search for, and random seed; float radius = 0.2; float seed = 8008135; //stalking prey (finding a list of points to infect); int neighbours[] = nearpoints(0,@P,radius,5); //hopefully grabbing a random one out of the stack of many; float array_length= len(neighbours); //random number between 0 and the length of the list of neighbours; int targetp = rint( rand(seed) * array_length); //looking up point ID in list of neighbours; int point_to_infect = neighbours[targetp]; //actually infect the point, if it is food; if (point(0,"infection",point_to_infect) == 0){ setpointattrib(0,"infection",point_to_infect,1); }; I haven't any clue what's going on, I got no errors other than a little green line under the local variable "targetp" when it gets created. I've attached my .hip! It might be something else I'm doing wrong. I hope you can help me, thanks in advance, Sasbom active infection.hip -
I have four visible platonic objects in the viewport here in this scene, but wehn i display the information on the end loop ive got 48? how can i split them or randomize there position? Lines_001.hip

Hey guys, I'm growing some objects using volumes (scene is attached) and I'd like to have motion blur on the moving/growing areas. I do have some velocity on the volume, in order to control it's growing direction, but i have no idea on how to transfer it to the mesh itself. here's how the setup looks like: Thx Volume.Growth.Velocity.v1a.hiplc

Looking the way to make this beauty I did some setup, but unfortunately, I'm loosing something important because I can't make the same or close shape, I mean thin and long. My setup is working for shapes like corals - massive, expandable, cone.... Thanks for any advice, the scene is below. grow_v001.hip
