gl-fbo-matching
Compare two gl-fbo instances' contents for matching pixels. There are certainly smarter ways of doing this but this is the simplest :)
Usage
channels = matching(fbo1, fbo2, [threshold])
Returns an array of values: one for each channel (RGBA). A value of 1 means that
all of the pixels in fbo1
match those in fbo2
, and a value of 0 means that
none of them do.
Optionally, you can pass in a threshold
value to limit the comparison's
sensitivity – effectively, setting the maximum distance between two pixels'
values before considering that pixel matching. Defaults to 0.
Note that using this function will result in
gl.bindFramebuffer(gl.FRAMEBUFFER, null)
being called.
