Nodes > Math > Geometric > Normalize

Returns the input vector normalized so that its length equals 1.

To guard against NaNs, which behave differently across devices, we implement Normalize as:

vec3 Normalize(vec3 v) {
    float lengthSquared = dot(v, v);
    float l = (lengthSquared > 0.0) ? 1.0 / sqrt(lengthSquared ) : 0.0;
    return v * l;
}
