3D-Voronoi with openScad is possible

thingiverse

OpenSCAD only provides a basic framework for creating 3D models, but it lacks a dedicated tool for generating 3D Voronoi cells directly within the software. I have been searching for such a tool, but my efforts were in vain until I decided to create one myself. After some trial and error, I discovered how to generate 3D Voronoi chunks using a small function that takes a set of Voronoi cores as input. This core function can be used to subtract or intersect the resulting 3D structure with any design. To illustrate the capabilities of this tool, I have applied it to various geometric primitives and shared the STL files, screenshots, and photos of the parts online. In principle, it is possible to use this tool on any object, regardless of its complexity. However, be aware that the calculation time increases exponentially with the number of Voronoi cores, so start with a small number of cores and gradually increase them until you achieve the desired result. The results are well worth the wait, as they provide a unique and visually striking effect by wrapping or passing through the object, depending on your design. You can find the published files here and let me know if you are interested in using my library. I developed it during my free time, combining my passion for OpenSCAD with my fascination for Voronoi patterns, which I find truly captivating. Some of my friends describe them as spacey and futuristic. Since discovering this method, my 3D printer has been working non-stop to produce these designs, thanks in large part to the interest generated by my creations. The cool thing about 3D Voronoi patterns is that rapid prototyping is the most practical way to build them, whereas injection molding for mass production would require expensive form-building with shifters, making each part a unique and valuable individual item. This makes it perfect for gifts or any design project where you want to create spacey, futuristic art. Not limited to candle holders alone! If you like my work, I'll send you the complete code along with further explanations for minimal obligations and keep you updated on any new developments. Perhaps you've already created some amazing designs that could benefit from a new Voronoi pattern? Maybe this tool can help you reduce material usage and weight in a creative way, saving resin or other materials while enhancing your design's appearance. The library, including the license and source code, is available for individual use at just 15 euros. To register and obtain the library, simply drop me an email, and we'll discuss further steps, payment, questions, service, and updates. Feel free to use the provided STL files for any purpose; I'll be uploading more examples soon. Best regards, and thank you for any feedback! Andreas Augsburg, Germany captayne@systragon.de PS: I'm still working on new features and examples for my library. It's also possible to Voronoi-ize existing STL files by importing them into the SCAD scene as a child module, using code like this: 3D_VoronoiizzerAKL( type="CYLINDER", dim=dim, n=120, thickness=2, walls=20, round = 3, seed = 9, showDots=false, renderit=true) import("cat.stl"); To those registered, I'll share updates on the code and examples via email in the future. More examples will follow soon. For those who prefer not to use my library, you can intersect a large Voronoi structure STL with your own designs to achieve a similar effect.
