A compact add-on written entirely in Python, listed in the Blender extensions library. Its pipeline uses the White–Nylander formula and the Hubbard–Douady distance estimator before extracting the isosurface.
Mandelbulb Generator adds 3D Mandelbulb and Julia fractal generation to Blender. Geometry is generated from a Signed Distance Field evaluated with NumPy and converted into a mesh using the Surface Nets algorithm, an approach that produces smoother and more accurate surfaces than simple voxelization methods.
The add-on works from a Mandelbulb tab in the 3D View: click Add Mandelbulb, then adjust parameters, and the mesh is automatically regenerated whenever values are modified. Controls include SDF grid resolution, grid size, power in the White–Nylander formula, max iterations, escape radius, and a Julia mode where the constant c stays fixed while Julia C controls the shape. Distortion options add coordinate offset and a twist that applies a progressive rotation at each iteration, producing helical or spiraling structures. Surface Nets settings cover smooth normals and iso level.
All parameters can be animated with Blender keyframes, including power animation, transitions between Julia fractals, progressive iso-level variation, and dynamic twisting. The add-on regenerates Mandelbulb objects whenever the current frame changes. It is compatible with Blender 5.1 and newer.
Mandelbulb Generator is best for blender users creating and exploring Mandelbulb and Julia fractal geometry, including animated fractal forms.
Mandelbulb Generator is completely free to download and use.
Mandelbulb Generator is compatible with Blender 5.1 and newer. The add-on's documentation describes it as a Mandelbulb fractal generator for Blender 5.1, and version 1.0.2 is listed as compatible with Blender 5.1 and later. If you run an older release of Blender, it falls outside the stated compatibility range, so using Blender 5.1 or a newer version is the safest way to ensure the add-on functions as described.
Mandelbulb Generator requires Blender 5.1 or later and NumPy, which is included with Blender. No additional external dependencies are required. The Signed Distance Field is evaluated using vectorized NumPy operations, so having NumPy available is essential to how the add-on generates geometry. Because NumPy ships with Blender, a standard Blender 5.1+ installation should already meet the requirements without any extra setup or third-party libraries.
Mandelbulb Generator adds a Mandelbulb tab in the 3D View. Open that tab, click Add Mandelbulb, then adjust the parameters to achieve the result you want. The mesh is automatically regenerated whenever parameters are modified, so changes update as you work. Parameters include SDF grid resolution, grid size, power, max iterations, escape radius, distortion offset, twist, and Surface Nets settings. Enabling Julia mode switches the output to a 3D Julia fractal controlled by the Julia C value.
Mandelbulb Generator supports keyframe animation, and all parameters can be animated using Blender keyframes. Documented examples include power animation, transitions between different Julia fractals, progressive iso-level variation, and dynamic twisting effects. The add-on automatically regenerates Mandelbulb objects whenever the current frame changes, so animated parameter values are reflected in the geometry across the timeline. This makes it possible to build evolving fractal forms rather than only static single-frame meshes.
Mandelbulb Generator is listed as free here and is distributed under the GNU General Public License v3.0 or later. The extension does not require special permissions. For the current licensing terms, source code, and any updates, refer to the developer's page on GitHub. Because it is released under the GPL, the license governs how you may use, modify, and redistribute the add-on, so reviewing those terms directly is recommended before integrating it into a project.
