In this post I will describe a process of compiling Hello World example from OpenVDB library. I will take the first example from OpenVDB Cookbook. However instead of building the whole OpenVDB library I will take advantage of precompiled OpenVDB library shipping with Houdini. In this post I will assume that you have at least very basic understanding of compiling process.

In this post I will publish summary of setting up and fiddling a bit with Universal Scene Description (USD) on Linux. It will mostly contain my understanding of the concepts behind USD and a compilation guide for Ubuntu based OS.
Originally I wrote this article for an assignment during my Technical Directing studies at Filmakademie Baden-Wuertemmberg. Parts regarding compiling Maya plugin for USD were written by Tim Lehr.
In this post I will try to explain principles behind implementation of the research paper Shaping particle simulations with interaction forces published by DreamWorks in 2014.
This technique allows us to create forces on particles which can result in variety of interesting motions, one of them resembling water behavior. This approach is more efficient than complex liquid simulations since it does not include volumetric operations (as in FLIP solvers for example) and is also easy to control and to combine with any other particle forces. I did this implementation in Houdini and VEX, but principles apply to any other software.

Hello everybody,
in this post I will explain how I achieved rendertime displacement on moving volumes using Arnold. Project file is included (at the bottom of the post).
In this post I will show and explain how I created rain effects. Project file is included (at the bottom of the post).
In this post I will show how I achieved plastic deformations with Houdini’s FEM solver. Here is video with results.
Lately there has been a lot of research in area of volumetric effects. One interesting enhancement to volumes is rendertime displacement. It is not that difficult to set up and results are great. You can achieve high resolution volume with low res input volume. In this post I will show how it can be set up with Arnold and Houdini.
In this post I will describe how to create twirl deformer for geometry and volumes. I needed to create tornado-like motion and found it quite easy to do in Houdini. Here is my solution.
I want to get a little bit more into coding so I am making up small exercices. I want to implement simple things first and hopefully later I will manage to do something bigger 🙂
For a long time I had this idea of playing with interpolations. They are very often used in CG so why not? Good resources on interpolation methods are here and here.
Trying to make things properly
