  1. Hi there! I want to do a procedural animation where I randomly change the transformation every second or so. For example at frame 1 posX is 0, stands still and at frame 50 it moves to a random pos within 10 frames, pauses for 50 frames and moves to next random pos within 10 frames, pauses for 50 frames, moves to next random pos and so on. Unfortunately my knowledge of CHOPs is rather limited and I couldn't figure out how to do it with expressions based on @Time. Any ideas? Cheers, J.
  2. Thanks so much for the effort, Max. Looks like a great approach, but I couldn't really get it to work. Ended up using a force field for the top of the logo. But I learned quite a bit by going through your setup. Cheers!
  3. Hello! I'm trying to make an effect where a logo emerges from a tank with a viscous fluid. I want to have the liquid quickly flow off the logo once it emerged. It has a round surface, similar to the torus I exchanged it for in the hip-file I attached. I'm aware of viscous fluid's stickiness and turned on "slip on collision" and also tried the "gas stick on collision" cheat I found in some older thread, as well as using normals to drive the velocity. however some particles always stay on top of the surface and won't flow off. What would be a smart way to cheat and clear the surface of the fluid? Thanks in advance! J. 190620_Instagram_FlipTankExample.hiplc
  4. Hello, I'm trying to create an effect very similar to the one in the reference video, where particles move through this channel and creep over this bubble. I tried different approaches like vellum grains, regular particles and came closest with the lava shelf tool. But then the individual particles are not touching the surface of the bubble and the overall movement of the particles looks too much like a fluid. I actually want the distance between the particles to stay constant. I think some PBD approach would work best, but can't quite figure it out. Any ideas? Thanks in advance.

  5. Hello! I'm trying to visualize data from a csv file as a node tree (similar to Houdini's Network View). I also want to be able to animate it's sequential growth from top to bottom. What would be the best approach to do this? I'm familiar with getting data into Houdini via the Table SOP. But I can't quite figure out how to do the tree structure. I've attached some sample data and a corresponding mockup. Thanks in advance! NodeGraph_Data.csv
  6. Thank you and sorry for the late reply! While this does give me an interesting effect, it's not quite what I'm looking for. Now all the point values remain at their position, but I want to add them to each other over time. Like stacking up.
  7. Hi Houdini-people. Been following this great community for a while, but never posted anything. So: Hello! I'm currently working on data visualizations about climate change. Houdini works great for this and so far it has been surprsingly easy to get the data in there via the table import SOP. The basic idea is this: I want to visualize the CO2 emissions from 1750 - 2013 (!). I was given data sets for each year. A friend helped me with some data wrangling and now I have a point grid for each year with lat/long data and the CO2 emission. So far it all works pretty well, see image ... Currently I simply put an expression in the file path of the table import SOP to skip through the CSV for each year. What I'm trying to do now, is not showing only the current values of the year per each frame. But add these values cumulative over time, showing the total CO2 emission. Hope this explains it well enough. I guess there are a few ways to do it (attribute wrangle, VOP SOP, solver ...?), but I can't quite figure it out. Any help and pointing into the right direction would be really appreciated. Thanks in advance!
