Volumes 101: Adding Colliders To Our Solver
Added 2017-11-17 07:37:15 +0000 UTCIn the final video of our volume growth setup we'll add collision geometry to our solver in order to be able to further art direct where our growth is happening. I promise this is the last video for this particular setup. I feel we now have conquered most of Houdinin's VDB/SDF functionality and can move on to other neat volumetric setups :)
For rendering the visual used in our videos you'll need the Hamarikyu Bridge B HDR from http://www.hdrlabs.com/sibl/archive.html

Hi mo, what values or parameters, control the velocity or speed of the simulation?

2020-03-03 08:43:49 +0000 UTCHow do you achieve the high frequency details in the screenshot? This setup is great but my result is very blobby. I'd love to get those little holes and ridges you have there

2019-05-16 00:36:15 +0000 UTCHi, trying to work on Curvature_07.hipnc I am facing two problems. First, the initial bgeo from file plugged in the solver is missing, or instructions on how to genenrate it. Second hipnc does not allow me to use the redshift plugin. Thanks anyway for this great serie. Malik

2018-10-29 18:00:30 +0000 UTCHey André, danke für das Lob und die berechtigte Frage! Da ich allerdings kein Spanisch spreche hier meine Antwort auf Englisch (das ist für alle einfacher): If I'm interpreting the google translate version of your question correctly, you wanted to know if there's a way around having to run the solver each time. Yes indeed there are a few: 1. Cache out the result you like via file cache SOP and load that as static geo. Or... 2. Append a timeshift SOP after the solver and set it to the frame you'd like to have as static geo. Or... 3. Instead of the solver use a for loop with feedback and let it run as many iterations as needed to get to a state you like. These are the options I could think of out of my head - there might be a few others too :) Cheers, Mo

2018-10-29 10:47:13 +0000 UTCIncreíble Soy un usuario muy nuevo de houdini. Solo he estudiado durante 8 meses. Tus videos me están ayudando mucho. Todavía no entiendo mucho, pero al menos puedo hacer los ejercicios. Tengo una pregunta: En cierto marco me gusta el resultado que tengo. ¿Es posible hornear este marco sin tener que calcular siempre el SoverNode?

2018-03-15 17:26:24 +0000 UTCCool, do you have a link to that? It was one of the early setups that I tried to get working when starting out learning Houdini. Odforce was quite helpful then - I think there's a huge thread on this kind of effect. This one is difficult to UV as it changes its topology quite a bit. One could try to write a custom advection using VEX or openCL and advect UV coordinates together with the surface. OR wait - maybe one could also directly store UV coordinates in a VDB and advect that using the VDBAdvect SOP... Interesting indeed!

2017-11-19 21:58:01 +0000 UTCPretty similar to Ian Farnsworth setup, thanks for the explanation, looking forward to new stuff. PS.: Is there a way to UV this? I tried with an attrib transfer after sim with no luck
