Creating painterly art style in games and preparing assets for NPR (non-photorealistic rendering) requires more than just fancy shaders. In this post I will cover what I learned from my 3D painterly style studies made as scenes for Sketchfab. A while ago I turned a watercolor painting to a 3D…

An introduction to mathematically generate the sound waveforms and create any sound you wish with endless variations — This post will cover how to generate sounds procedurally — by constructing the waveforms mathematically, using sinus waves — in Unity 3D and C#. The end goal is to synthesize a procedural piano, which you can play using the keyboard. …

A short break down of the use of several VFX tricks in my latest scene. This includes setting up a stencil portal, dealing with render order issues, as well as mixing baked and procedural animation, stylized ghosts, volumetric fog with lighting, flames and texturing of the scene. As usual, you…

This is a beginner friendly introduction to color theorem for artists and programmers alike. I try to give a solid foundation to start understanding color by differentiating color as a light wave, activation of receptors in our eyes, perceptual model and color spaces and mixing. …

A break down of making a realtime interactive fog respecting arbitrary boundaries, using fluid simulation and compute shaders in Unity 3D. In the article I go over an easy method to generate a mask for arbitrary boundaries, and discuss two further methods to counter issues regarding terrain with overhangs and…

A simple intuitive breakdown of fluid simulation for programmers and technical artists. Instead of complicated mathematical expressions, I try my best to offer an easy geometrical understanding of fluid simulation. The implementation is done in Compute shaders using Unity 3D, however the ideas are technology independent. As usual, you can…

Content Aware Fill is a powerful tool. I would love the day Blender would have something like that integrate in. Until then, we can use a small trick with projection mapping, to bring the content aware fill functionality of Photoshop to Blender. Here is a short break down of this…

A short walk through of a little hack on how to convert a portrait painting or a drawing to a 3D model with little texturing or the usual hassles such as proper unwrap. For this I am using Blender, although you could use any software. As the base I am…

A detailed break down of creating an animated aura effect for a sword or an object using shaders in Unity3d. The technique however is as usable for Unreal or any other environment. The mesh used for the demo is from Arms Museum. As usual, you can find the code on…
