i32 the Mandelbrot Set：Blender 几何节点插件

This is a basic Mandelbrot set using only 32-bit integers.

When I began developing this setup in early 2025, bit shifts were emulated using Divide and Modulo operations – inherently slower methods. Thanks to the introduction of the Bit Math Node in Blender 4.5 LTS and its developers, full-fledged bit shifts are now available. This significantly simplified solving specific computational tasks.

The setup is suitable both for educational purposes, such as visually understanding some principles of the IEEE 754 floating-point standard, and for creating images or videos, since the Mandelbrot set itself is beautiful and contains a vast number of magnificent patterns.

A number consists of a Mantissa (Integer), an Exponent (Integer), and a Sign (Boolean).

The i32 dAddSub node handles Add and Subtract. The i32 dMulPow2 node handles Multiply and Power2 (multiplying a number by itself).

The other nodes are auxiliary (overflow control, sign control, and others).

Three display modes: Mesh, Points, and Pixels (cube instances instead of points).

Be sure to watch the Tutorial Video – and thank you for your interest in my setup!

WARNING: Resolution and Iterations severely impact performance. Always increase values gradually in small steps, never abruptly, and strictly according to your system's capabilities. Ignoring this can cause crashes or excessive hangs.

The setup was created with future potential in mind to fully unlock the power of Integers. Thanks to Node To Python by Brendan Parmer, it became an Add-on for Blender.
