Dot Matrix with Spacing

Post by mikestjean »

Hi frens

I am looking to achieve a dot-matrix look with ability to also adjust the spacing of the dots. The built-in Dot Screen fx is great but only allows size of the dots, while keeping them at an absolute spacing.

Any thoughts on how to recreate the Dot Screen effect in Wire, in a way that allows for adjusting the spacing of the dots as well?

I'm actually noticing that the density of the dots is effected by the luma / white of the image.

The intention is to create a low-res computer look:

So I have discovered the technique is called 'Stipple' , and one way to achieve this is to use the Mode -> Bitmap (Dither) feature in Photoshop. I haven't figured out how I might pull this off in real-time in Resolume yet. I fear it might be quite GPU intensive.

For anyone following along at home, JAB Visuals created the effect already for a delightfully affordable £10 on Gumroad.

That plug-in looks nice indeed.

Since 7.20 we allow reading back pixels to the cpu to be able to perform calculations based on pixel values.
This allows quite some nice tricks as you can see in the new Strokes effect.

I attached a patch which samples the colors and uses the luminance to scale the meshes being drawn. You can easily expand/change it to get a more low tech look. Adding some noise to the grid would work quite well.
