Differential curve growth

What an awesome and fun thread. Thanks to everyone for sharing and a big thanks to the guys at Entagma. I took their setup and modified it a bit to hold the shape of the starting geometry better. There are some issues when Selective Remeshing (remeshing by group) is enabled. Every once in a while the Remesh SOP will generate a model with patches of inverted normals. Haven't figured out a clean way of dealing with that as the Facet SOP and PolyDoctor don't work a hundred percent of the time. hollowCube.mp4 differentialGrowth_hollowCube.hip

Toms "Learning Houdini" Gallery

Over the last couple of weeks I started to learn Houdini, partly from tutorials by Entagma and others, partially by implementing things I worked on in Grasshopper for Rhino (which is single threaded and rather slow for larger assets) over into the Houdini world. This one started out from the Entagma tutorial on differential growth but I then first extended it to avoid the text areas and today implemented a first version of a threading solution to make it look more like yarn: This one is similar to an older test I once did in Softimage XSI and Arnold, but this time with Houdini, exported as FBX and rendered with my favourite renderer Thea Render: And the last one for today was a study on how one can visualise noise in Houdini. It uses a solver and the trails node. I found it hard to make it look really subtle in Mantra, so in the end I created poly wires and also exported it to Thea Render via FBX: Thanks everybody on Odforce for knowledge and inspiration!!! Cheers, Tom

pluralsight.com Houdini courses?

Right! This is the most motivation I've had to learn math since cramming for my placement exam so I wouldn't have to suffer though another remedial math class.

pluralsight.com Houdini courses?

My math skills are atrocious. Luckily Houdini is fun and math can really help make some awesome things in the software. Who would have thought years after pulling C minuses in basic math classes I want to soak up as much math as I can manage now.

Volumetric rendering in Houdini and Octane

Hello everyone, This training is a series of small projects that will cover the process of creating a variety of volumetric effects in Houdini and rendering them using Octane. This training is primarily focused on modeling and rendering custom volume effects. Over the course of this training I'll cover a variety of effects which include building and rendering clouds, making a pyro shader and using the blackbody emission to control the pyro shader. We'll also build custom volume effects such as a gas flame and a nebula. Finally we'll take a look at building controllable volume lights and volume fog. NOTE: Additional lessons for Redshift and Mantra will be added to this training towards the end of October. (They will be available separately for download depending upon your renderer of choice. These parts will be charged separately.) For further details click on the link given below http://www.rohandalvi.net/volumetrics

ROP Output Driver Vs. File Cache ?

dependency means that one caching node needs to be evaluated before the next one starts. You often have situations, where sometimes parallel processing is possible, and sometimes it needs to be sequential

ROP Output Driver Vs. File Cache ?

but You can combine them, by fetching the ficecache nodes with a fetch into rop. If You work in sop, You can write out, if You want to wire dependencies You can switch to ROP network

ROP Output Driver Vs. File Cache ?

in ROPs you can chain a number of outputs together to create a dependency network - the file cache would require a different approach and the Output drive can't import geometry - so different operators for different uses

strange force

hi everyone, i would like to share my latest houdini work. the initial motivation cames from entagmas strange attractor tut (thanks!). based on thomas attractor i build up three force fields to get this kind of complex structures. listen to the music with headphones. tom.

Constraint woes - pinning two different packed objects together

Here you go! Keep in mind that this setup will work only if your hard constraint type is "position". To make it work for both pos and rotation you have to compute matrix for each static object and transfer rotation to constraint points. GluePinTest_FIX.hipnc
