**NAME**

s3d_vector_angle - calculate angle between two vectors

**SYNOPSIS**

#include<s3d.h>floats3d_vector_angle(constfloatvector1[],constfloatvector2[]);

**DESCRIPTION**

Calculates and returns the angle between vector1 and vector2. Please note that the resulting angle is between 0 and PI, therefore not covering the whole period! To convert in degrees just do result*180/M_PI. All vectors should have the format float[3]. More info on wikipedia. http://en.wikipedia.org/wiki/Vector_(spatial)
