The Book of Shaders: dot

WebGLSL has very flexible notation for referring to the components of a vector. One way to access them is with array notation. For example, if v is a four-component vector, then its components can be accessed as v [0], v [1], v [2], and v [3]. But they can also be accessed using the dot notation as v.x, v.y, v.z, and v.w. WebWe see two built-in GLSL functions here: dot returns the dot product of the given vectors, and min returns the minimum value passed to it. dist will end up being a value from 0.0 to 1.0 and distFactor will be the inverse.
