 * Linear interpolation between two vec3.
 * Can be used, for example, to interpolate between two RGB colors.
 * @param a - First vec3
 * @param b - Second vec3
 * @param t - Time "t".
 *   - Vector A is returned for values smaller than or equel to 0.
 *   - Vector B is returned for values greater than or equal to 1.
 *   - An interpolation between vectors A and B is returned otherwise.
