The forthcoming MathPaint beta now has a fairly complete noise-rendering feature set. There are several algorithmic noise-generation modes – Perlin, Billow, Ridged, and Voronoi – as well as MathPaint’s own random-shape drawing mode.
In addition to the feature, I’m starting to build the collection of templates that will ship with the app as starting points – here’s a screenshot of some Perlin noise applied as well as the templates window showing about a dozen noise templates that were added today:
While the templates are all grayscale, any color gradient can be applied to these noise patterns. In the case of the random shape patterns, instead of a gradient there’s a pen color and a background color. As with all graphics layers in MathPaint, the layer opacity can be changed to make the noise a semi-transparent overlay of other generated content (or as image export, for use in other graphics programs).
Here are a few output examples from the noise templates, with colors changed:
 |
| Cloudy Perlin noise |
 |
| Ridge-noise ‘sandstone’ |
 |
| Gold billow noise |
 |
| Grassy random segments (angle-constrained) |
 |
| Chunky Voronoi noise in muted colors |
