Here is Optical Data Flow in Houdini from My Houdini Junk series. In this R&D, we obtained the motion and velocity data of a footage with the optical flow technique. As a result, we obtained a new simulation using the data we acquired.
My Houdini Junk Series Vol.01
My Houdini Junk Series are archives of my R&Ds which are self-produced / self-developed o I learned from blogs/web sites/tutorials. My Houdini Junk mostly developed in Pre/After Project processes or independently of this processes.

What is Houdini?
Houdini is a 3D animation and special effects application developed by Side FX, a twenty-five-year-old Toronto-based company. Houdini is designed to create 3D animations and 3D effects in movies, TV, video games and virtual reality. Houdini is renowned for combining the worlds of film, TV, video games and virtual reality into one powerful platform.
The former flagship of Side Effects, PRISMS, a suite of 3D graphics tools, served as a foundation for Houdini's development.
Unlike other 3D animation software, Houdini uses a node-based procedural workflow that simplifies the job of making the updates you apply to the model while refining your work. Unlike programs such as Maya or Blender, it allows you to revert to a previous version in your work and update over the old version.
While Houdini is primarily used for dynamic environments and particle effects, it also includes a full set of tools for artists who want to use it in other areas such as modelling, animation or rendering.
What exactly does do?
Houdini is known for its advanced dynamic simulation tools that allow the creation of highly realistic visual effects. And it has an efficient workflow designed for small studios and individual artists.
New efficiency in software means cutting-edge effects can be achieved on less advanced hardware. What really sets Houdini apart from other 3D animation software is its computational nature.
Assets are usually created with a set of nodes algorithm. The advantage of this workflow is that it allows artists to create detailed objects in relatively short steps, unlike other programs.
Although Houdini is known for special effects, it includes all the tools that the best 3D modeling programs have to offer. Houdini also includes standard geometric models and animations.
The program comes with the powerful render engine Mantra, but it also supports 3rd party render engines like Renderman.
it has a node-based system that provides a flexible working environment for creating shaders and creating CG effects. It has a powerful system for creating smoke and fire simulations and a compiler for layered image effects.
Houdini offers scripting via various APIs, but Python is the language of choice for most packages. It allows the creation of custom tools and plugins, as well as built-in scripting and automation of specific tools.
Houdini is especially suitable for visual effects artists with a technical background. It provides all the editing tools expected in 3D software, but is known for its VFX tools and node-based procedural nature of its workflow.
Beginners note that features have a steep learning curve due to the procedural design. The key to success with Houdini is to have knowledge about mathematics and algorithms.
For this reason, Houdini is an easier program to learn for those with a background in programming and math, such as technical artists. For those who do not have experience in these matters, you can find many Houdini tutorials to improve themselves.
When you start using the program, if you are familiar with programs such as Autodesk Maya and 3DS Max, you will see that it is more flexible to use than these programs. And artists who can successfully learn the software will find that they produce many effects without the need for any traditional artistic interaction.
Teams will enjoy working with it because every part of the project can be easily modified at any point in the development process.
it offers a free version of the Houdini FX kit for students and hobby use to create personal and non-commercial projects.
While this version of Houdini lets you compose your work and save it to your computer, the only drawback is that it adds a watermark. You can download the Houdini Apprentice version for free here.
In which creative projects is used?
It's is a complete package for VFX studios working for games, movies and television. Its tools are powerful, reliable, customizable and designed for high-end production.
It means faster production and low budget power usage thanks to procedural workflow. For this reason, Disney is among the key users who use it in the films Frozen and Zootopia. Also, HBO's Game of Thrones uses it for some visual effects.
In the Video Game world, many video game studios also use Houdini. Games like Call of Duty and League of Legends are examples of this.
Houdini is a useful tool for creating simulations of clouds, smoke or fire, as well as liquids and fabric. Although Houdini can render any scene, the software is best known for its fluid-like effects and other simulations like it.
it is powerful when used to create complex simulations that use large amounts of data. Studios choose Houdini to create large special effects systems that integrate with complex scenes.
Studios often use software like Maya to handle modeling and hardware features and use it to integrate complex simulated effects.
Game designers, visual effects artists, and technical directors use Houdini daily to create state-of-the-art effects and enhance their work with simulated environments.
