This tutorial introduces how to script an add-on for the pixel art editing program Aseprite. We do a series of “hello world” exercises to create dialog menus in the interface. We then look at two more in-depth tools: an object-oriented isometric grid and a conic gradient. Unlike prior tutorials…

This tutorial explores how to make a grid of regular convex hexagons in Blender with Python, then how to turn that script into an add-on. An example render made with the add-on looks like so:

Unity, Processing, Godot, Blender, Three.js — This tutorial explores how to generate a capsule through script in five 3D environments. Or rather, how to approximate a capsule with a mesh. We’ll look at two game engines, Godot and Unity; one modeling suite, Blender; one creative coding IDE, Processing; and one browser-based tool, Three.js. …

This tutorial introduces Blender’s BMesh as a way to create and edit meshes in Blender through Python. The benefit of BMesh is that we have access to higher level operations than we would working with vertices and face indices; however, we avoid overhead incurred with bpy.ops, …

This tutorial introduces how to make patterns with complex numbers in Blender. It builds off of tutorials on creative coding in Blender and scripting Cycles nodes. For that reason, it assumes some prior acquaintance with Blender’s Python API and Open Shading Language (OSL). In this tutorial, we’ll go over the…

This tutorial introduces how to edit curves in Blender with Python scripting. In the following, we’ll look at how to render a curve; convert a curve to a mesh; distribute objects along a curve; adjust movement with F-curves; move objects along a curve; create…

This tutorial introduces moving virtual cameras for 2D and 3D Processing sketches. First it looks at strategies for wrapping screen elements, like the background, when the camera is fixed. After introducing shaders and working with multiple renderers, it creates a 2D camera. It then creates the 3D equivalent, looking at…

This tutorial, a follow-up to Creative Coding in Blender, focuses on creating patterns on materials in Blender’s Cycles renderer. There are a few reasons why patterning can be challenging at first. Tutorials for OpenGL Shading Language (GLSL) abound, but the node-based visual programming in Blender has a slightly different toolset…

This tutorial explores how translation, rotation and scale — taken together under the umbrella term affine transformations — work in Processing (Java mode). An alternative to matrices, based on a quaternion, is then created to show how we can ease between ‘keyframes.’ To keep this tutorial from being any longer…
