50% threshold colour filter?

[Kevin Camp]

i don’t know of an effect that will create a mosaic with triangles…

the easiest/most direct way i can think of, is to create a layer with the triangle pattern that you want (if it is a repeatable pattern, you could create one triangle and use motion tile or repetile to fill the pattern out. then use that as a track matte for a layer with mosaic on it and overlay that on the same layer with mosaic on it….

obviously you’ll need to change the mosaic a bit from one layer to another, or it will just look like a rectangular mosaic pattern. for the b/w effect, try tint and adjust the contrast with levels.

the best way would be to create each triangle as a layer, add the fill effect and link the fill effect and the layer’s anchor point to a sampleImage() expression that that is sampling the image at that point, then you’ll need to duplicate the triangle layer out to create a grid (you won’t be able to use motion tile/repetile, but expressions can help there too.

i won’t have time to work out those expressions today, but if you post, and/or search, in the expressions forum you should be able to get some good help… try searching for sampleImage to learn about that expression and also search for ‘layers grid’ for expressions that can help order your triangles more easily…

Could you fake it with CC Pixel Polly, using polygons instead of textured polygons?
