Earns its place in the Blender Extensions library as a focused generator for Sierpinski fractals, adding 2D triangles and 3D pyramids directly to the Add > Mesh menu. The latest update extends the size range and corrects a distance factor bug.
Sierpinski Triangle is an add-on for Blender that generates Sierpinski triangles in 2D and Sierpinski pyramids in 3D. Beyond the standard fractal shapes, it can stack any mesh into a 3D Sierpinski pyramid, so the recursive form isn't limited to a single primitive. Once installed and enabled, the generator lives in the 3D Viewport under Add > Mesh > Sierpinski.
The current release, version 1.0.4, allows larger Sierpinski triangles and fixes a negative distance factor bug, so objects are flipped when the distance factor is negative. The add-on is compatible with Blender 4.2 LTS and newer, requires no special permissions, and is distributed under the GNU General Public License v3.0 or later.
Built by Jonny-B, the add-on is available through the Blender Extensions library, where it can be dragged and dropped into Blender or installed from disk. The source is maintained on GitHub, and a demo video is available. At around 4 KB, it's a compact tool focused on generating Sierpinski fractals.
Sierpinski Triangle is best for blender users who want to generate 2D Sierpinski triangles and 3D Sierpinski pyramids, including pyramids built by stacking a custom mesh.
Sierpinski Triangle is completely free to download and use.
Sierpinski Triangle is compatible with Blender 4.2 LTS and newer, so any current release in that range can run it. The add-on works in the 3D Viewport, where its generator appears under Add > Mesh > Sierpinski once enabled. Version 1.0.4 added support for larger Sierpinski triangles and fixed a bug where objects were flipped when the distance factor was negative. If you run an older Blender build, check the developer's page to confirm which releases are supported before installing.
Sierpinski Triangle can be installed by dragging and dropping the add-on file into a running Blender window, or by downloading it and using Install from Disk. Jonny-B also publishes the add-on through a remote repository you can add to Blender's extensions list. Once installed and enabled, open the 3D Viewport and choose Add > Mesh > Sierpinski to generate a Sierpinski triangle or pyramid. The download is around 4 KB, and the source is maintained on GitHub.
Sierpinski Triangle is listed as free here and is distributed under the GNU General Public License v3.0 or later. The add-on requires no special permissions in Blender. For current licensing terms or any changes, check the developer's page. Its source is maintained on GitHub under the same GPL-3.0 license, so you can review or modify the code within the terms of that license. Downloads on the Blender Extensions listing have passed well over a thousand.
Sierpinski Triangle can stack any mesh into a 3D Sierpinski pyramid, in addition to generating flat 2D Sierpinski triangles. You add it from the 3D Viewport through Add > Mesh > Sierpinski after enabling the add-on. Version 1.0.4 introduced support for larger Sierpinski triangles and corrected a negative distance factor bug that previously flipped objects. A demo video is available if you want to see the add-on first. For further detail, the developer's page and GitHub repository cover the current build.
