Triangulator Pro – Free Illustrator Tool for Voronoi & Triangle Patterns
I’m thrilled to share Triangulator Pro with you – an improved version of my original Triangulator script for Adobe Illustrator. This handy tool makes it simple and fun to create Voronoi and triangulated patterns that turn your shapes into organic textures and geometric designs.
Voronoi Tool
The Voronoi Tool lets you transform any vector artwork into a vibrant mosaic of polygonal cells, creating an organic, natural look – like cracked stone, animal skin, or abstract geometry.
Key Features:
- Automatic Voronoi pattern generation
Simply select your object and generate a Voronoi pattern that intelligently fills the shape. The tool calculates edge – based polygons, but may occasionally miss points – which can be fixed by increasing cut accuracy (with a trade-off in speed). - Color randomizing
The tool retains and works with your existing color. Select a base color (e.g. yellow) and Voronoi Pro will generate variations around it, allowing you to stylize your shapes while keeping a cohesive look. Want your giraffe to be red instead of green? No problem – just tweak and regenerate. - Add detail with random Points
Need more texture? Add additional points within your shape to create a denser Voronoi mesh. This is perfect for simulating fur, stone textures, or detailed organic surfaces. - Top path control for custom shapes
Want more creative control? Use a top path feature add a custom vector shape – to define where Voronoi points are placed. This enables possibilities like drawing an eye, creating emphasis in certain areas, or generating patterns that follow specific contours.
In the video, a giraffe illustration is transformed using Voronoi Pro — creating a textured look resembling red gemstones or skin texture patterns.
Triangulator Tool
The Triangulator Tool offers a modern, upgraded way to convert any shape into a sleek, triangulated form – ideal for low-poly portraits, tech-style illustrations, and stylized digital art.
Key Features:
- Auto Triangulation
With one click, the tool generates a complete mesh of triangles that fill your vector shape. It analyzes either random or custom-defined point positions to ensure visual variety. - Top Path Support for Point Placement
Just like in the Voronoi tool, you can define a top path to manually control where triangulation points are placed. This gives you precision for stylized effects – such as placing more detail in key facial features or design areas. - Color Variation Settings
Start with a base color (e.g. pink), then apply automatic variations based on lightness, hue, or saturation. This brings a subtle, artistic gradient effect to your triangles — without needing manual recoloring. - Randomized Patterns
Prefer unpredictability? Let the script place random points inside the shape for a more abstract, generative look. It’s fast and effective for creating backgrounds or experimental designs.
Whether you’re working on illustrations, textures, or experimental graphics, Triangulator Pro makes it easy to bring complexity and natural beauty to your vector work. And the best part? It’s completely free!
