How to do Environment Scattering in Houdini with Machine Learning?

Master 3D Forest Scattering with Machine Learning & Real Data
The usage of real forest data for scatter environments can revolutionize the way environment artist generate their scatters, offering unprecedented realism and depth in digital environments. By leveraging real forest data, we can now populate vast digital landscapes with 3D scatterings that mirror the complexity and diversity of natural forests. Machine learning accelerates this process, allowing for the rapid generation of these environments with stunning accuracy and detail.
This method can quickly generate diverse forest ecosystems that accurately reflect real-world complexity and variability. Once the model is trained, environments can be created much faster than traditional procedural methods, potentially reducing production times. And it's making the process more accessible to artists without extensive technical backgrounds in procedural generation.
Dive into the world of creating hyper-realistic 3D forests using machine learning. This tutorial guides you through the process of using real forest data to train a model that brings your digital environments to life. Perfect for visual effects artists, game developers, and machine learning enthusiasts, I cover everything from data preparation to model training and integration with Houdini.

Amazing

Lovely work, cant wait to learn more!

[@oriolmanzanoduran]

Thank you so much for your kind words!!!

Great video. I didn't expect another upload 😅😊

Love this. More content like this. I wish this was detailed and longer. I still wasn't able to understand how you were training the model and bringing it to Houdini. do you have any resources for Houdini + AI materials where you are using real trained data to learn about?

[@oriolmanzanoduran]

Thank you so much for your feedback and enthusiasm! Understanding the intricacies of training machine learning models and integrating them with Houdini can indeed be complex. To help you understand what is happening take a look at the houdini file and code, I've shared it free in github.com/mrnsapple/DailyTips/tree/main/projects/TreeScattering/src. And to learn more about Houdini + Ai subscribe to my newsletter oriolmanzano.com/newsletter, I publish every week about AI and machine learning in visual effects.

Now, you have this, could the model predic the type of Soil in Houdini according to the neighbor tree around?

[@oriolmanzanoduran]

Good question! what I am performing here is a supervised learning where the target variable is the tree type("Cover_Type") based in other parameters such as the terrain elevation and slope or the presence of water. So the trained algorithm is not going to give you soil information, just what type of tree has more probability to appear in the location.
To make the algorithm tell you as well what soil to use, you can just simply include the soils types ("Soil_Type*") together with the tree_type("Cover_Type") in the dataframe of target variables to predict.
Hope this helps and answers the question!!!!

tu hiciste el curso de houdini en megacursos ?
Lo recomiendas para alguien nuevo en los VFX?

[@oriolmanzanoduran]

Para empezar lo mejor es aprender de cursos que estén al día con las últimas versiones de Houdini y que enseñen a hacer efectos complejos que puedas poner en tu reel. No recomiendo que compres ese curso porque la versión de houdini es muy antigua y los efectos muy básicos. En www.sidefx.com/tutorials/ puedes encontrar muy buenos tutoriales de todos los niveles
