Does anyone know of a patch or even a tutorial that can help create hexagonal or other polygonal pixelation on a photo or video?

hexagon-pixelation

Not sure if it will work but you could try jit.gl.slab with the td.repos file. Search for the example file. Send a hexagonal image into its right inlet.

you could create a hexagon shape using jit.gl.mesh, and multiply it with jit.gl.multiple, based on whatever pixelation algorithm you're using. alternatively you could create the hexagon using a geometry shader. there's also some jitter recipes where quad vertices are calculated from a single point, that could be modified. check our recipe 36, 37, and 38.

I've been working with Max/MSP for many years, but almost nothing with Jitter, so I don't have a pixelation algorithm and wouldn't know what to do with one. I'm guessing it takes a shape into which a sample of the input image/video at the center point of the shape (hexagon) is taken/averaged. The larger the shape, the more input pixel value are averaged?

I took a look at at recipe 36-38, but I'm not sure where to start.

Also, isn't jit.gl.mesh and jit.gl.multiple 3D effects? I'm looking for a 2D pixelation result. Sorry if I misunderstood.

There is a great patch from Ben Bracken for that :

Wicked, thanks Matmat! That's really helpful. Now, I just need to find a way to use these for pixelation.
