The vertex shader only accepts the texture coordinates as a vertex attribute and forwards the coordinates to the fragment shader. By default, it will also guarantee that the fragment will receive the properly interpolated coordinate based on its position in a triangle: layout (location = 0) in vec3...

(let [xf (comp (map inc) (filter even?))] (transduce xf + [1 2 3 4 5 6 7 8 9 10])) ;; => 30 This example creates a transducer assigned to the local xf and uses transduce to apply it to some data. The transducer add's one to each of it's inputs and only returns the ...

(def xf (filter keyword?)) Apply to a collection, returning a sequence: (sequence xf [:a 1 2 :b :c]) ;; => (:a :b :c) Apply to a collection, reducing the resulting collection with another function: (transduce xf str [:a 1 2 :b :c]) ;; => ":a:b:c" Apply to a collection, and...
