Before this plugin became widely known in the Rhino community, users often had to rely on external software like Adobe Illustrator or spend hours manually clicking through curve points to trace organic patterns and logos.
This comprehensive guide covers everything you need to know about vectorization plugins and workflows in Rhino. 1. Native Rhino Vectorization Tools (No Plugin Required)
Converting raster images into clean, editable vector geometry is a core workflow for architects, industrial designers, and digital fabricators. While Rhino is an incredibly powerful tool for 3D modeling and precision drafting, its native image tracing capabilities can sometimes require manual workarounds.
Converts curve segments into exact lines and true arcs where possible. vectorize plugin rhino 2021
If you require advanced control over thresholding, corner smoothing, and path optimization, utilizing an external vector engine remains highly efficient.
(formerly known as RhinoGold) is a comprehensive jewelry design plugin that includes a dedicated Raster to Vector command. This command converts an image into a group of curves, which is particularly handy for translating 2D logos or ornamental motifs into 3D models for jewelry and small object design.
Bring your image into the Rhino workspace. You can use the standard Picture command to place the image as a surface plane in your viewport. This allows you to scale it to the exact real-world dimensions before vectorizing. 3. Run the Vectorize Command Before this plugin became widely known in the
There were various scripts available on the Rhino Forums and Food4Rhino that aimed to automate the tracing of high-contrast images. These scripts typically took a black-and-white "mask" image and generated outline curves.
Here is the standard methodology for generating clean vector curves from an image asset. Step 1: Pre-Process Your Image
: Load the raster image you wish to vectorize into Rhino 2021. If you require advanced control over thresholding, corner
Take a flat raster image (like a JPG or PNG) and generate smooth, editable NURBS curves directly in the workspace.
You are building a generative script, need to process multiple images sequentially, or want to map image data directly into 3D surface textures.
If you plan to extrude these shapes into 3D solids (using ExtrudeCrv ) or use them for laser cutting, the curves must be fully closed loops. Use the SelOpenCrv command to highlight any problematic paths, and use Join , Match , or CloseCrv to seal the gaps. Simplify Lines and Arcs
To get clean, smooth curves that are ready for lofting, extruding, or manufacturing, keep these tips in mind:
Run the SelDup command and delete duplicates to prevent a laser cutter from burning the same path twice.
