Hi everybody. This is the second part of the tutorial, which explains the basics of a technology called ray marching for rendering a 3D scene using a shader. In the first part, we modeled a simple scene with a sphere, a cylinder, and a cube, and this time we will demonstrate how to properly light such a scene and calculate shadows.

Hi everybody! Let's try something a little different today - an introduction to creating complete 3D scenes using shaders. Yes, I know - this technology, called ray marching, has been described many times in other tutorials, and it's hard to come up with something entirely new. Still, I think it wouldn't hurt to add such a video to our collection because I plan to expand on this topic in a new series, and it would be good to have a reference for the absolute basics.

Hi everyone! Let's use the Godot shading language to recreate an effect that falls into the category of a large number of small objects following a trajectory. It consists of simple elements, in this case, ellipses, that orbit along certain curves and together create interesting-looking patterns. So, let's get started.

Hi everyone! In this video, we will take a look at a technique that allows us to create very interesting pseudo-random patterns using functions we know from previous tutorials, such as plasma, plexus, or lightning. This time, we will use a method called domain warping or domain distortion, and the result will be this infinitely changing fog that we can see in the background right now.

Hey everybody! Do you remember the simulation of an old CRT monitor I created about a year ago? We had programmed various issues and imperfections characteristic of these devices, such as white noise, rounded corners, ghosting, and so on. This time, we’ll simulate a more modern device: an LCD with its typical pixel grid and less vibrant colors. Unlike CRT, such a shader is elementary, as we’ll see right away.

Hi everybody! Do you remember the 3D tunnel created using a texture mapped onto the inside of a cylinder? I think the result looked quite decent, especially when the camera was set in motion, giving us the impression of flying through an endless tube that disappears into distant darkness. This time, let's try something similar, but without textures and with a triangular shape.

Hi everyone! I think that a simulation of a raindrop trickling down a window is a very nice effect, and if there are more of them, they can be both highly useful and visually striking in games. So, let’s explore how this shader works from a programming perspective.

Hello everyone! This is the first video I'm recording in 2025, so I hope it turns out well. This time, I’d like to show how we can use a shader to create a digital clock, which we will then control using a script. So, let’s get started.

Hey everybody! And welcome to the last tutorial of this year. Of course, this is definitely not the absolutely final tutorial, as I will continue with a new batch of learning materials in January. So, how are we ending the year 2024? We will be implementing blobby objects, also known as metaballs. Yes, exactly what you see on the screen right now. So, let's get started.

Hi everyone! Let's add a simple effect simulating a TV signal disturbance to our collection. It actually resembles typical artifacts when playing recordings from a low-quality VHS tape, but it's up to each programmer to find a suitable use for it. And because it's a very simple algorithm with just a few lines of code, this video will be relatively short as well. So let's create it.

Hey everyone! The end of 2024 is slowly approaching, so I thought it would be good to add at least one more post-processing effect before diving into something more complex next year. This time, it’s again about layering, with each layer shifted differently using a noise texture and rotation. With a bit of imagination, the result can resemble a painting where the colors have blurred and blended together slightly. Let’s take a look at how this algorithm works.

Hey everyone! Let’s create a simple shader that will shake our screen or an element on the screen as if an earthquake has occurred. This could be quite useful in various platformers, right? And, in fact, it’s very easy to implement. Let’s get coding.
