This Geometry Nodes setup generates procedural 3D Mandelbulb and Julia set fractals utilizing continuous volume grids and closure features. It includes two independent node systems for the main Mandelbulb formulation and the Julia formulation, which both share a core utility group to process the complex fractal math.

Users control the rendered region of the volume by manipulating the containing object's geometry in Edit Mode or by adjusting the position attribute transforms inside the node tree. The visual output can be modified by altering the exponent and multiplier values across the modifier and the shader, along with the order variable of the fractal structure.
