Procedural generation

Making a seamless Perlin noise in C#

How to mix maths and pseudo-random noises for procedural generation!

Nodevember #1

Last November, the Nodevember event took place. This event focuses on doing procedural rendering with 3D software and it offers daily-themed challenges: the goal is to start with the simplest possible 3D model (a cube, a sphere…) and to create amazing visuals only with nodes and procedural shading.

“L’Oulipo”: mixing maths and literature

In 1911, the French writer André Gide said that: “Art is born from constraint, thrives in the struggle and is killed by freedom” (personal translation of the original quote). Although some might disagree and believe that one should create in total liberty, others have decidedly followed this path to eventually come together as a group of writers and mathematicians called the “OuLiPo”.

AI & Art with Cali Rezo (6): Conclusion & Final Notes

To end this series of articles on the AI & Art project I realized in collaboration with Cali Rezo, today I would like to give you some of my thoughts on this project and on AI in general, plus some info on the tools we used and on Cali’s upcoming events.

AI & Art with Cali Rezo (5): Cali’s Interview

Over the past few weeks, we explored several questions related to AI and its application to art generation or analysis. Before finishing the series, let’s look at things from Cali’s point of view and talk a bit about artists and technology…

AI & Art with Cali Rezo (4): Explainability and uncertainty of AI models

In the third article of the series, we discussed how to apply AI to art analysis. Even if our results were not as conclusive as we’d hoped, they still raised a few questions that we will tackle today: what is really happening in these black box models that are neural networks? And to which extent can we assess how certain a model is of its predictions?

AI & Art with Cali Rezo (3): Analytical models

In the last article, we focused on VAEs and GANs for image generation. This time, we’ll talk about analyzing images and trying to identify classes. We will also take this opportunity to talk about the usual traps and limits of AI classification.

AI & Art with Cali Rezo (2): Generative models

To start off with this series of articles on the AI & Art project I did in collaboration with Cali Rezo, we’ll discuss some common generative models and how we applied them to her artwork to create new images in a “Cali-like” style.

AI & Art with Cali Rezo (1): Project & Goals

Nowadays, machine learning (ML) is a red-hot topic which is discussed everywhere in various ways. More and more companies are relying on AI as part of their production process, be it in the domain of finance, medicine, management, art… This last application of ML algorithms, in particular, is really interesting to me. And, since the great abstract painter Cali Rezo shares this interest, we decided we would collaborate on a project to study how to apply AI to art.

A peek at L-systems

Today, let’s continue with procedural generation. So far, we have seen various tools to generate specific structures, so let’s take a look at another type of generator: L-systems.

A peek at Markov chains

Last time, we introduced the basic concepts of our name generator and we saw how webcrawlers can help us gather information easily and efficiently. Now, it’s time to use this information to actually produce some words! To do so, we will rely on statistics and Markov chains.

A peek at cellular automata (2)

Last time, I talked about cellular automata, and more precisely Conway’s Game Of Life. To continue on this topic, I searched for small applications we can derive from the concept of cellular automaton and I eventually settled for one: a RPG-like map generation algorithm.
