Building a Monoline Hershey Font Script in Cinema 4D
Typography meets scripting when you bring the Hershey simplex font dataset into Cinema 4D. This project demonstrates how to convert the classic monoline stroke definitions into Python splines, enabling you to render text procedurally inside your 3D scenes.
Why Hershey Simplex?
The Hershey fonts are a set of vector-based stroke fonts developed in the 1960s for early computer graphics. They’re lightweight, monoline, and perfect for procedural generation. Each glyph is defined by a series of coordinates and “pen up” markers, making them easy to translate into spline geometry.
From Dataset to Cinema 4D
The original dataset is stored as arrays of coordinates. For example, the capital S is defined as:
“`python
“S”: [(17,18),(15,20),(12,21),(8,21),(5,20),(3,18),(3,16),
(4,14),(5,13),(7,12),(13,10),(15,9),(16,8),(17,6),
(17,3),(15,1),(12,0),(8,0),(5,1),(3,3)]
Each (x,y) pair is a point, and (-1,-1) indicates a pen lift (new stroke segment). By iterating through these points, we can build Cinema 4D splines.
The Python Script
The script:
- Defines a dictionary of glyphs (
hershey). - Prompts the user for text input via a dialog.
- Iterates through each character, looks up its coordinates, and builds spline segments.
- Inserts the resulting splines into the Cinema 4D scene.
This allows you to type any string and see it rendered as monoline text.
Extending the Font
We expanded the dataset to include:
- Uppercase A–Z
- Lowercase a–z
- Digits 0–9
- Punctuation and symbols (
. , - ! ? : ; " ' ( ) [ ] { } / \ @ # $ % ^ & * = + < >) - Turkish glyphs (
Ç, Ş, Ğ, İ, I, Ö, Üand their lowercase forms)
This makes the script capable of handling full ASCII text plus Turkish-specific characters, ensuring linguistic inclusivity.
Next Steps
- Kerning and spacing: Use glyph width values instead of fixed spacing for more natural text flow.
- Styling: Add options for stroke width, color, or extrusion to turn splines into 3D text.
- Dynamic loading: Parse the Hershey dataset file directly, so you don’t need to manually paste coordinates.
Conclusion
This Cinema 4D Python script transforms the Hershey simplex dataset into a powerful procedural text tool. It’s lightweight, customizable, and now supports Turkish glyphs — making it both technically robust and culturally inclusive.
