Derivatives and Geometry Use screen-space derivatives to find triangle normals. Do the same via a geometry shader. Use generated barycentric coordinates to create a wireframe. Make the wires fixed-width and configurable. This tutorial covers how to add support for flat shading and showing the wireframe of a mesh. It uses advanced rendering techniques and assumes you're familiar with the material c

Biomes and Rivers Have rivers originate from high and wet cells. Create a simple temperature model. Use a biome matrix for cells, then tweak it. This is part 26 of a tutorial series about hexagon maps. The previous part added a partial water cycle to our map generation algorithm. This time we'll supplement it with rivers and temperature and assign more interesting biomes to cells. This tutorial is

This tutorial is an introduction to mesh deformation. We'll turn a mesh into bouncy mass and poke at it. This tutorial follows Cube Sphere. It is a continuation of the same kind of mesh manipulation and we'll use the cube sphere as our test model. It is suitable for Unity 5.0.1 and up. Applying some pressure. Scene Setup We start with a scene that has a single cube sphere object at its center. You

In this tutorial we'll create a simple grid of vertices and triangles. This tutorial assumes that you are familiar with the basics of Unity scripting. See Clock for these basics. Constructing a Fractal provides an introduction to coroutines. This tutorial has been made for Unity 5.0.1 and up. Beneath complex appearance lies simple geometry. Rendering Things If you want to visualize something in Un

This tutorial is deprecated. Fractals are intriguing and often beautiful. In this tutorial we'll write a small C# script that manifests some fractal-like behavior. You're assumed to know your way around Unity's editor and know the basics of creating C# scripts. If you've completed the Clock tutorial then you're good to go. This is an old tutorial and will be upgraded, but it's still fun to do. Men

In this tutorial we'll create a rounded cube with a single mesh. This tutorial follows Procedural Grid. It has been made for Unity 5.0.1 and up. Rounded cubes in various shapes. Compositing a Cube After tackling 2D grids, the next logical step is to procedurally generate 3D structures. Let's have a look at a cube. Conceptually, it consists of six 2D faces that are positioned and rotated such that

In this Unity C# tutorial you will create a custom visualization for arrays and lists in the editor. You will learn to create a custom editor use SerializedObject manipulate a SerializedProperty that represents an array or list use an enumeration for option flags use GUI buttons This tutorial comes after the Custom Data tutorial. This tutorial is for Unity version 4.3 and above. Unity's default wa

In this tutorial you will create your own texture, and make it interesting with pseudorandom noise. You'll learn to Create and fill a texture; Visualize a slice through world space; Use delegates; Use a hash array for 1D, 2D, and 3D hashing; Compute Value noise; Compute Perlin noise; Create fractal noise; Use a gradient. This tutorial builds on the foundation laid by previous tutorials. If you com

This tutorial will take you from creating a simple line all the way to editing your own Bézier splines. You'll learn to Create a custom editor; Draw in the scene view; Support editing via the scene view; Create Bézier curves and understand the math behind them; Draw curves and their direction of movement. Build Bézier splines by combining curves; Support free, aligned, and mirrored control points;

In this tutorial we'll create a very simple endless running game. You'll learn to generate a layered background; reuse objects; use simple physics; detect input to make the player jump; implement a power-up; write a small event manager; switch stuff on and off on demand; make a minimal GUI. This tutorial has been superseded by Runner 2. You're assumed to know your way around Unity's editor and kno

Star, an introduction to WYSIWYG editing Introduction In this tutorial you will create a simple star component and write your own custom editor for it. You will learn to dynamically generate a mesh support WYSIWYG editing support editing in the scene view This tutorial comes after the Custom List tutorial. This tutorial is for Unity version 4.3 and above. We start with the finished Custom List tut

Visualizing Math Create a prefab. Instantiate multiple cubes. Show a mathematical function. Create a surface shader and shader graph. Animate the graph. This is the second tutorial in a series about learning the basics of working with Unity. This time we'll use game objects to build a graph, so we can show mathematical formulas. We'll also make the function time-dependent, creating an animating gr
