WebCalculating the magnitude of a vector is only the beginning. The magnitude function opens the door to many possibilities, the first of which is normalization. Normalizing refers to the process of making something “standard” or, well, “normal.”. In the case of vectors, let’s assume for the moment that a standard vector has a length of 1. WebDec 1, 2010 · December 01, 2010 12:05 PM. I'm very confused with the length function in hlsl. From what i can understand it gives me the length of a vector so for example for: length (float2 (4.0, 3.0)) It should calculate the square root of 4^2 + 3^2 = 16 + 9 = 25 i.e. 5. I'm obtaining 4... what the helll ????
