Learning resources about VFX and CG

I would like to share with you a collection of presentations, research papers and theses on various topics of VFX or CG.

lib_cover

I am used to collecting good learning resources and keeping them around in case I will need them later. So it happened that my small list grew and I realized that I have quite interesting things collected from various places.

So I decided to create a repository at GitHub where I will continue to gather useful information which I come across. I am not trying to re-create a database of all recent cutting-edge research. It is more oriented on resources which are easier to understand, like presentations with notes and pictures 🙂 I have been most interested in resources about FX and volumetrics, so it is missing stuff in other areas like cloth simulation etc..

And this is also one of the motivations to host it on a git: similar-minded people can contribute with their areas of interest and hopefully we will end up with a nice pool of information which we can quickly refer to when needed.

I tried to make an easy system for adding new entries – simply add them into a json library file and the page will be automatically updated. More info about that in the repo.

I hope that you will find this resource useful 🙂

Batch textures conversion tool

Hello,
I would like to share with you my latest tool that I developed in my spare time. It’s aim is to help you with batch pre-conversion of textures for VFX render engines.
It will batch convert your textures into formats like rat (for Mantra), tx (for PRMan or Arnold), rstexbin (for Redshift). It works within Houdini, Maya or as a standalone application. You can see screen capture of this tool in action here 🙂

Houdini tip | Render any node in background

Hello, I would like to share with you a recent small script I did for more convenient local rendering from Houdini.

node_tree

In some Houdini builds I had issues with background renders, and I also miss Background render feature on some nodes. So I created this shelf tool, which will enable you to start a background render of a selected node or nodes. Using this tool you can render nodes with dependencies, fetch nodes, merge nodes… Just select the node and press button. It will start up a background process in terminal, where you will see progress of the rendering.

Currently it works on Linux and Windows. Feel free to contribute to the repository and extend it for MacOS. Also if you encounter any issues let me know, or even better create a pull request 🙂

Here you can find script repository with set-up instructions.

Happy rendering 🙂

Artistic style transfer setup guide

In this post I will explain how to set up a linux environment for running style transfer implementations from GitHub repositories. I assume that you have a Nvidia GPU, linux distribution and a working knowledge of linux. If you get into any troubles, just drop me a line. It was done as a part of my studies at Filmakademie Baden-Wuerttemberg.

There are many implementations on a GitHub and here I will show how to make the three of them working (which I had previously tested and used):

Here you can check some tests and results which I did with those three implementations.

  • mtx2_low full image
    • In the columns different implementations are used (in the same order as in the list above), the rows are using different styles.
  • mtx_lowfull image
    • I also tested the last implementation with a CG rendering, here you can see comparison of different rendering output vs different styles (renderings by Kiana Naghshineh)
