Here's what you get when you search for "normalize":

```glsl
## Normalize
Calculate the unit vector in the same direction as the input vector

### Declaration
float normalize(float x)  
vec2 normalize(vec2 x)  
vec3 normalize(vec3 x)  
vec4 normalize(vec4 x)

### Description
normalize() returns a vector with the same direction as its 
parameter, x, but with length 1.

### See Also
length(), distance(), dot()
```
