We’ll be implementing complex number operations in Python, OSL and Blender Cycles nodes until we get to pattern-making. For vector implementations where 2D vectors are not distinguished from 3D, care must taken that the z component be treated as zero. A complex number’s argument matches the vector’s heading the modulus, a vector’s length or magnitude. In Cartesian coordinates, the x component carries the real number the y component, the imaginary. The similarity between complex numbers and two-dimensional (2D) vectors means that vectors can be used to store and to visualize them. The phase is often symbolized by the Greek letter phi, φ. When i is raised to an even whole number -1 results, i is an imaginary number, the square root of -1. Backgroundįirst, a refresher on the math behind complex numbers. This tutorial was written for Blender 2.8 beta. Since the details of implementing complex number functions can take a while, readers are encouraged to skip the initial section of this tutorial where they are defined, look over what patterns can be made with these functions, then return if interested. Last, we’ll look briefly at how a fractal pattern can be mixed with other patterns (for shaders) and modifiers (for meshes generated by Python). how to create 2D patterns (the Mobius transformation, Mandelbrot set, Julia set, Pickover stalks and tricorn).how to define complex number operations with nodes, Python and OSL.For that reason, it assumes some prior acquaintance with Blender’s Python API and Open Shading Language (OSL). It builds off of tutorials on creative coding in Blender and scripting Cycles nodes. They register anonymous statistical data on for example how many times the video is displayed and what settings are used for playback.No sensitive data is collected unless you log in to your google account, in that case your choices are linked with your account, for example if you click “like” on a video.This tutorial introduces how to make patterns with complex numbers in Blender.
