GLSL 4.0: Discarding Fragments to Create a Perforated Look

WebAug 9, 2011 · Each component is compared to 0.2 using the built-in function greaterThan, and the result is stored in the bool vector toDiscard. The greaterThan function compares the two vectors component-wise, and stores the Boolean results in the corresponding components of the return value. WebOne expression might be better than the other. For example: result = 0.5 * (1.0 + variable); result = 0.5 + 0.5 * variable; The first one may be converted into an add followed by a multiply. The second one is expressed in a way that more explicitly allows for a MAD operation.
