I am attempting to play back a small video and use nearest neighbor
interpolation to acheive that lovely pixelated look.
Quite fitting, given the material ;) Should warn people before such
dangerous trips down memory lane :)
How does one then apply a nearest neighbor interpolation? Im
assuming I have to build a simple CIKernel to do this with fract and
samplerCoords or somesuch?
Your problem doesn't like in the filter, but in the stupid billboard:
mouse-over the image output from the filter, and you'll see that the
resolution is really low (36x45) -- the billboard _always_ does linear
interpolation to scale the image, regardless of how you set the CI
filter stuff.
What you'll want to do is this:
Find the image resizer, and upscale the movie output by some big value
(x8 or x16 is good, but feel free to experiment).
Then, change your filter to essentially be a mosaic function, like this:
kernel vec4 multiplyEffect(sampler image)
{
return sample(image,//samplerCoord(image));
vec2(
floor(samplerCoord(image).x/8.)*8.,
floor(samplerCoord(image).y/8.)*8.)
);
}
You can change the 8.'s to be whatever you decide to scale up by.
This'll give you some 1980's pixelated goodness :)
