WebIt is reasonable to assume that dot product operations, despite the complexity of them, will be fast operations (possibly single-cycle). Given that knowledge, the following code can be optimized: vec3 fvalue1 ; result1 = fvalue1 . x + fvalue1 . y + fvalue1 . z ; vec4 fvalue2 ; result2 = fvalue2 . x + fvalue2 . y + fvalue2 . z + fvalue2 . w ; WebGLSL has a few built-in variables, one of which we will see in the fragment shader example. These are special variables that are a part of the programmable pipeline that the API knows to look for and knows how to associate. ...
